While some of these standards may seem arbitrary, they somehow seem +to result in a solid, consistent codebase. + +It is possible that the code base does not currently comply with these +guidelines. We are not looking for a massive PR that fixes this, since that +goes against the spirit of the guidelines. All new contributions should make a +best effort to clean up and make the code base better than they left it. +Obviously, apply your best judgement. Remember, the goal here is to make the +code base easier for humans to navigate and understand. Always keep that in +mind when nudging others to comply. + +The rules: + +1. All code should be formatted with `gofmt -s`. +2. All code should pass the default levels of + [`golint`](https://github.com/golang/lint). +3. All code should follow the guidelines covered in [Effective + Go](http://golang.org/doc/effective_go.html) and [Go Code Review + Comments](https://github.com/golang/go/wiki/CodeReviewComments). +4. Comment the code. Tell us the why, the history and the context. +5. Document _all_ declarations and methods, even private ones. Declare + expectations, caveats and anything else that may be important. If a type + gets exported, having the comments already there will ensure it's ready. +6. Variable name length should be proportional to its context and no longer. + `noCommaALongVariableNameLikeThisIsNotMoreClearWhenASimpleCommentWouldDo`. + In practice, short methods will have short variable names and globals will + have longer names. +7. No underscores in package names. If you need a compound name, step back, + and re-examine why you need a compound name. If you still think you need a + compound name, lose the underscore. +8. No utils or helpers packages. If a function is not general enough to + warrant its own package, it has not been written generally enough to be a + part of a util package. Just leave it unexported and well-documented. +9. All tests should run with `go test` and outside tooling should not be + required. No, we don't need another unit testing framework. Assertion + packages are acceptable if they provide _real_ incremental value. +10. Even though we call these "rules" above, they are actually just + guidelines. Since you've read all the rules, you now know that. + +If you are having trouble getting into the mood of idiomatic Go, we recommend +reading through [Effective Go](http://golang.org/doc/effective_go.html).

Upcoming +features and bugfixes for a component will be added to the relevant milestone. If a feature or +bugfix is not part of a milestone, it is currently unscheduled for +implementation. + +* [Registry](#registry) +* [Distribution Package](#distribution-package) + +*** + +### Registry + +The new Docker registry is the main portion of the distribution repository. +Registry 2.0 is the first release of the next-generation registry. This was +primarily focused on implementing the [new registry +API](https://github.com/docker/distribution/blob/master/docs/spec/api.md), +with a focus on security and performance. + +Following from the Distribution project goals above, we have a set of goals +for registry v2 that we would like to follow in the design. New features +should be compared against these goals. + +#### Data Storage and Distribution First + +The registry's first goal is to provide a reliable, consistent storage +location for Docker images. The registry should only provide the minimal +amount of indexing required to fetch image data and no more. + +This means we should be selective in new features and API additions, including +those that may require expensive, ever growing indexes. Requests should be +servable in "constant time". + +#### Content Addressability + +All data objects used in the registry API should be content addressable. +Content identifiers should be secure and verifiable. This provides a secure, +reliable base from which to build more advanced content distribution systems. + +#### Content Agnostic + +In the past, changes to the image format would require large changes in Docker +and the Registry. By decoupling the distribution and image format, we can +allow the formats to progress without having to coordinate between the two. +This means that we should be focused on decoupling Docker from the registry +just as much as decoupling the registry from Docker. Such an approach will +allow us to unlock new distribution models that haven't been possible before. + +We can take this further by saying that the new registry should be content +agnostic. The registry provides a model of names, tags, manifests and content +addresses and that model can be used to work with content. + +#### Simplicity + +The new registry should be closer to a microservice component than its +predecessor. This means it should have a narrower API and a low number of +service dependencies. It should be easy to deploy. + +This means that other solutions should be explored before changing the API or +adding extra dependencies. If functionality is required, can it be added as an +extension or companion service. + +#### Extensibility + +The registry should provide extension points to add functionality. By keeping +the scope narrow, but providing the ability to add functionality. + +Features like search, indexing, synchronization and registry explorers fall +into this category. No such feature should be added unless we've found it +impossible to do through an extension. + +#### Active Feature Discussions + +The following are feature discussions that are currently active. + +If you don't see your favorite, unimplemented feature, feel free to contact us +via IRC or the mailing list and we can talk about adding it. The goal here is +to make sure that new features go through a rigid design process before +landing in the registry. + +##### Proxying to other Registries + +A _pull-through caching_ mode exists for the registry, but is restricted from +within the docker client to only mirror the official Docker Hub. This functionality +can be expanded when image provenance has been specified and implemented in the +distribution project. + +##### Metadata storage + +Metadata for the registry is currently stored with the manifest and layer data on +the storage backend. While this is a big win for simplicity and reliably maintaining +state, it comes with the cost of consistency and high latency. The mutable registry +metadata operations should be abstracted behind an API which will allow ACID compliant +storage systems to handle metadata. + +##### Peer to Peer transfer + +Discussion has started here: https://docs.google.com/document/d/1rYDpSpJiQWmCQy8Cuiaa3NH-Co33oK_SC9HeXYo87QA/edit + +##### Indexing, Search and Discovery + +The original registry provided some implementation of search for use with +private registries. Support has been elided from V2 since we'd like to both +decouple search functionality from the registry. The makes the registry +simpler to deploy, especially in use cases where search is not needed, and +let's us decouple the image format from the registry. + +There are explorations into using the catalog API and notification system to +build external indexes. The current line of thought is that we will define a +common search API to index and query docker images. Such a system could be run +as a companion to a registry or set of registries to power discovery. + +The main issue with search and discovery is that there are so many ways to +accomplish it. There are two aspects to this project. The first is deciding on +how it will be done, including an API definition that can work with changing +data formats. The second is the process of integrating with `docker search`. +We expect that someone attempts to address the problem with the existing tools +and propose it as a standard search API or uses it to inform a standardization +process. Once this has been explored, we integrate with the docker client. + +Please see the following for more detail: + +- https://github.com/docker/distribution/issues/206 + +##### Deletes + +> __NOTE:__ Deletes are a much asked for feature. Before requesting this +feature or participating in discussion, we ask that you read this section in +full and understand the problems behind deletes. + +While, at first glance, implementing deleting seems simple, there are a number +mitigating factors that make many solutions not ideal or even pathological in +the context of a registry. The following paragraph discuss the background and +approaches that could be applied to arrive at a solution. + +The goal of deletes in any system is to remove unused or unneeded data. Only +data requested for deletion should be removed and no other data. Removing +unintended data is worse than _not_ removing data that was requested for +removal but ideally, both are supported. Generally, according to this rule, we +err on holding data longer than needed, ensuring that it is only removed when +we can be certain that it can be removed. With the current behavior, we opt to +hold onto the data forever, ensuring that data cannot be incorrectly removed. + +To understand the problems with implementing deletes, one must understand the +data model. All registry data is stored in a filesystem layout, implemented on +a "storage driver", effectively a _virtual file system_ (VFS). The storage +system must assume that this VFS layer will be eventually consistent and has +poor read- after-write consistency, since this is the lower common denominator +among the storage drivers. This is mitigated by writing values in reverse- +dependent order, but makes wider transactional operations unsafe. + +Layered on the VFS model is a content-addressable _directed, acyclic graph_ +(DAG) made up of blobs. Manifests reference layers. Tags reference manifests. +Since the same data can be referenced by multiple manifests, we only store +data once, even if it is in different repositories. Thus, we have a set of +blobs, referenced by tags and manifests. If we want to delete a blob we need +to be certain that it is no longer referenced by another manifest or tag. When +we delete a manifest, we also can try to delete the referenced blobs. Deciding +whether or not a blob has an active reference is the crux of the problem. + +Conceptually, deleting a manifest and its resources is quite simple. Just find +all the manifests, enumerate the referenced blobs and delete the blobs not in +that set. An astute observer will recognize this as a garbage collection +problem. As with garbage collection in programming languages, this is very +simple when one always has a consistent view. When one adds parallelism and an +inconsistent view of data, it becomes very challenging. + +A simple example can demonstrate this. Let's say we are deleting a manifest +_A_ in one process. We scan the manifest and decide that all the blobs are +ready for deletion. Concurrently, we have another process accepting a new +manifest _B_ referencing one or more blobs from the manifest _A_. Manifest _B_ +is accepted and all the blobs are considered present, so the operation +proceeds. The original process then deletes the referenced blobs, assuming +they were unreferenced. The manifest _B_, which we thought had all of its data +present, can no longer be served by the registry, since the dependent data has +been deleted. + +Deleting data from the registry safely requires some way to coordinate this +operation. The following approaches are being considered: + +- _Reference Counting_ - Maintain a count of references to each blob. This is + challenging for a number of reasons: 1. maintaining a consistent consensus + of reference counts across a set of Registries and 2. Building the initial + list of reference counts for an existing registry. These challenges can be + met with a consensus protocol like Paxos or Raft in the first case and a + necessary but simple scan in the second.. +- _Lock the World GC_ - Halt all writes to the data store. Walk the data store + and find all blob references. Delete all unreferenced blobs. This approach + is very simple but requires disabling writes for a period of time while the + service reads all data. This is slow and expensive but very accurate and + effective. +- _Generational GC_ - Do something similar to above but instead of blocking + writes, writes are sent to another storage backend while reads are broadcast + to the new and old backends. GC is then performed on the read-only portion. + Because writes land in the new backend, the data in the read-only section + can be safely deleted. The main drawbacks of this approach are complexity + and coordination. +- _Centralized Oracle_ - Using a centralized, transactional database, we can + know exactly which data is referenced at any given time. This avoids + coordination problem by managing this data in a single location. We trade + off metadata scalability for simplicity and performance. This is a very good + option for most registry deployments. This would create a bottleneck for + registry metadata. However, metadata is generally not the main bottleneck + when serving images. + +Please let us know if other solutions exist that we have yet to enumerate. +Note that for any approach, implementation is a massive consideration. For +example, a mark-sweep based solution may seem simple but the amount of work in +coordination offset the extra work it might take to build a _Centralized +Oracle_. We'll accept proposals for any solution but please coordinate with us +before dropping code. + +At this time, we have traded off simplicity and ease of deployment for disk +space. Simplicity and ease of deployment tend to reduce developer involvement, +which is currently the most expensive resource in software engineering. Taking +on any solution for deletes will greatly effect these factors, trading off +very cheap disk space for a complex deployment and operational story. + +Please see the following issues for more detail: + +- https://github.com/docker/distribution/issues/422 +- https://github.com/docker/distribution/issues/461 +- https://github.com/docker/distribution/issues/462 + +### Distribution Package + +At its core, the Distribution Project is a set of Go packages that make up +Distribution Components. At this time, most of these packages make up the +Registry implementation. + +The package itself is considered unstable. If you're using it, please take care to vendor the dependent version. + +For feature additions, please see the Registry section.

You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License.

There are a variety of tar serialization formats [2], and a key +concern here is ensuring a repeatable checksum given a set of inputs from a +generic tar archive. Types of transportation include distribution to and from a +registry endpoint, saving and loading through commands or Docker daemon APIs, +transferring the build context from client to Docker daemon, and committing the +filesystem of a container to become an image. + +As tar archives are used for transit, but not preserved in many situations, the +focus of the algorithm is to ensure the integrity of the preserved filesystem, +while maintaining a deterministic accountability. This includes neither +constraining the ordering or manipulation of the files during the creation or +unpacking of the archive, nor include additional metadata state about the file +system attributes. + +## Intended Audience + +This document is outlining the methods used for consistent checksum calculation +for filesystems transported via tar archives. + +Auditing these methodologies is an open and iterative process. This document +should accommodate the review of source code. Ultimately, this document should +be the starting point of further refinements to the algorithm and its future +versions. + +## Concept + +The checksum mechanism must ensure the integrity and assurance of the +filesystem payload. + +## Checksum Algorithm Profile + +A checksum mechanism must define the following operations and attributes: + +* Associated hashing cipher - used to checksum each file payload and attribute + information. +* Checksum list - each file of the filesystem archive has its checksum + calculated from the payload and attributes of the file. The final checksum is + calculated from this list, with specific ordering. +* Version - as the algorithm adapts to requirements, there are behaviors of the + algorithm to manage by versioning. +* Archive being calculated - the tar archive having its checksum calculated + +## Elements of TarSum checksum + +The calculated sum output is a text string. The elements included in the output +of the calculated sum comprise the information needed for validation of the sum +(TarSum version and hashing cipher used) and the expected checksum in hexadecimal +form. + +There are two delimiters used: +* '+' separates TarSum version from hashing cipher +* ':' separates calculation mechanics from expected hash + +Example: + +``` + "tarsum.v1+sha256:220a60ecd4a3c32c282622a625a54db9ba0ff55b5ba9c29c7064a2bc358b6a3e" + | | \ | + | | \ | + |_version_|_cipher__|__ | + | \ | + |_calculation_mechanics_|______________________expected_sum_______________________| +``` + +## Versioning + +Versioning was introduced [0] to accommodate differences in calculation needed, +and ability to maintain reverse compatibility. + +The general algorithm will be describe further in the 'Calculation'. + +### Version0 + +This is the initial version of TarSum. + +Its element in the TarSum checksum string is `tarsum`. + +### Version1 + +Its element in the TarSum checksum is `tarsum.v1`. + +The notable changes in this version: +* Exclusion of file `mtime` from the file information headers, in each file + checksum calculation +* Inclusion of extended attributes (`xattrs`. Also seen as `SCHILY.xattr.` prefixed Pax + tar file info headers) keys and values in each file checksum calculation + +### VersionDev + +*Do not use unless validating refinements to the checksum algorithm* + +Its element in the TarSum checksum is `tarsum.dev`. + +This is a floating place holder for a next version and grounds for testing +changes. The methods used for calculation are subject to change without notice, +and this version is for testing and not for production use. + +## Ciphers + +The official default and standard hashing cipher used in the calculation mechanic +is `sha256`. This refers to SHA256 hash algorithm as defined in FIPS 180-4. + +Though the TarSum algorithm itself is not exclusively bound to the single +hashing cipher `sha256`, support for alternate hashing ciphers was later added +[1]. Use cases for alternate cipher could include future-proofing TarSum +checksum format and using faster cipher hashes for tar filesystem checksums. + +## Calculation + +### Requirement + +As mentioned earlier, the calculation is such that it takes into consideration +the lifecycle of the tar archive. In that the tar archive is not an immutable, +permanent artifact. Otherwise options like relying on a known hashing cipher +checksum of the archive itself would be reliable enough. The tar archive of the +filesystem is used as a transportation medium for Docker images, and the +archive is discarded once its contents are extracted. Therefore, for consistent +validation items such as order of files in the tar archive and time stamps are +subject to change once an image is received. + +### Process + +The method is typically iterative due to reading tar info headers from the +archive stream, though this is not a strict requirement. + +#### Files + +Each file in the tar archive have their contents (headers and body) checksummed +individually using the designated associated hashing cipher. The ordered +headers of the file are written to the checksum calculation first, and then the +payload of the file body. + +The resulting checksum of the file is appended to the list of file sums. The +sum is encoded as a string of the hexadecimal digest. Additionally, the file +name and position in the archive is kept as reference for special ordering. + +#### Headers + +The following headers are read, in this +order ( and the corresponding representation of its value): +* 'name' - string +* 'mode' - string of the base10 integer +* 'uid' - string of the integer +* 'gid' - string of the integer +* 'size' - string of the integer +* 'mtime' (_Version0 only_) - string of integer of the seconds since 1970-01-01 00:00:00 UTC +* 'typeflag' - string of the char +* 'linkname' - string +* 'uname' - string +* 'gname' - string +* 'devmajor' - string of the integer +* 'devminor' - string of the integer + +For >= Version1, the extended attribute headers ("SCHILY.xattr." prefixed pax +headers) included after the above list. These xattrs key/values are first +sorted by the keys. + +#### Header Format + +The ordered headers are written to the hash in the format of + + "{.key}{.value}" + +with no newline. + +#### Body + +After the order headers of the file have been added to the checksum for the +file, the body of the file is written to the hash. + +#### List of file sums + +The list of file sums is sorted by the string of the hexadecimal digest. + +If there are two files in the tar with matching paths, the order of occurrence +for that path is reflected for the sums of the corresponding file header and +body. + +#### Final Checksum + +Begin with a fresh or initial state of the associated hash cipher. If there is +additional payload to include in the TarSum calculation for the archive, it is +written first. Then each checksum from the ordered list of file sums is written +to the hash. + +The resulting digest is formatted per the Elements of TarSum checksum, +including the TarSum version, the associated hash cipher and the hexadecimal +encoded checksum digest. + +## Security Considerations + +The initial version of TarSum has undergone one update that could invalidate +handcrafted tar archives. The tar archive format supports appending of files +with same names as prior files in the archive. The latter file will clobber the +prior file of the same path. Due to this the algorithm now accounts for files +with matching paths, and orders the list of file sums accordingly [3]. + +## Footnotes + +* [0] Versioning https://github.com/docker/docker/commit/747f89cd327db9d50251b17797c4d825162226d0 +* [1] Alternate ciphers https://github.com/docker/docker/commit/4e9925d780665149b8bc940d5ba242ada1973c4e +* [2] Tar http://en.wikipedia.org/wiki/Tar_%28computing%29 +* [3] Name collision https://github.com/docker/docker/commit/c5e6362c53cbbc09ddbabd5a7323e04438b57d31 + +## Acknowledgments + +Joffrey F (shin-) and Guillaume J.

Namespace and Subsystem + +This package provides you with a namespace type that allows you to specify the same namespace and subsystem for your metrics. + +```go +ns := metrics.NewNamespace("engine", "daemon", metrics.Labels{ + "version": dockerversion.Version, + "commit": dockerversion.GitCommit, +}) +``` + +In the example above we are creating metrics for the Docker engine's daemon package. +`engine` would be the namespace in this example where `daemon` is the subsystem or package where we are collecting the metrics. + +A namespace also allows you to attach constant labels to the metrics such as the git commit and version that it is collecting. + +2. Declaring your Metrics + +Try to keep all your metric declarations in one file. +This makes it easy for others to see what constant labels are defined on the namespace and what labels are defined on the metrics when they are created. + +3. Use labels instead of multiple metrics + +Labels allow you to define one metric such as the time it takes to perform a certain action on an object. +If we wanted to collect timings on various container actions such as create, start, and delete then we can define one metric called `container_actions` and use labels to specify the type of action. + + +```go +containerActions = ns.NewLabeledTimer("container_actions", "The number of milliseconds it takes to process each container action", "action") +``` + +The last parameter is the label name or key. +When adding a data point to the metric you will use the `WithValues` function to specify the `action` that you are collecting for. + +```go +containerActions.WithValues("create").UpdateSince(start) +``` + +4. Always use a unit + +The metric name should describe what you are measuring but you also need to provide the unit that it is being measured with. +For a timer, the standard unit is seconds and a counter's standard unit is a total. +For gauges you must provide the unit. +This package provides a standard set of units for use within the Docker projects. + +```go +Nanoseconds Unit = "nanoseconds" +Seconds Unit = "seconds" +Bytes Unit = "bytes" +Total Unit = "total" +``` + +If you need to use a unit but it is not defined in the package please open a PR to add it but first try to see if one of the already created units will work for your metric, i.e. seconds or nanoseconds vs adding milliseconds. + +## Docs + +Package documentation can be found [here](https://godoc.org/github.com/docker/go-metrics). + +## HTTP Metrics + +To instrument a http handler, you can wrap the code like this: + +```go +namespace := metrics.NewNamespace("docker_distribution", "http", metrics.Labels{"handler": "your_http_handler_name"}) +httpMetrics := namespace.NewDefaultHttpMetrics() +metrics.Register(namespace) +instrumentedHandler = metrics.InstrumentHandler(httpMetrics, unInstrumentedHandler) +``` +Note: The `handler` label must be provided when a new namespace is created. + +## Additional Metrics + +Additional metrics are also defined here that are not available in the prometheus client. +If you need a custom metrics and it is generic enough to be used by multiple projects, define it here. + + +## Copyright and license + +Copyright © 2016 Docker, Inc.

Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: + +* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`. +* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers. +* URL hosts, paths and query values can have variables with an optional regular expression. +* Registered URLs can be built, or "reversed", which helps maintaining references to resources. +* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes.

This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters. + +Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: + +```go +r := mux.NewRouter() +r.HandleFunc("/products/{key}", ProductHandler) +r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler) +r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler) +``` + +The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`: + +```go +func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) { + vars := mux.Vars(r) + w.WriteHeader(http.StatusOK) + fmt.Fprintf(w, "Category: %v\n", vars["category"]) +} +``` + +And this is all you need to know about the basic usage. More advanced options are explained below. + +### Matching Routes + +Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: + +```go +r := mux.NewRouter() +// Only matches if domain is "www.example.com". +r.Host("www.example.com") +// Matches a dynamic subdomain. +r.Host("{subdomain:[a-z]+}.domain.com") +``` + +There are several other matchers that can be added. To match path prefixes: + +```go +r.PathPrefix("/products/") +``` + +...or HTTP methods: + +```go +r.Methods("GET", "POST") +``` + +...or URL schemes: + +```go +r.Schemes("https") +``` + +...or header values: + +```go +r.Headers("X-Requested-With", "XMLHttpRequest") +``` + +...or query values: + +```go +r.Queries("key", "value") +``` + +...or to use a custom matcher function: + +```go +r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool { + return r.ProtoMajor == 0 +}) +``` + +...and finally, it is possible to combine several matchers in a single route: + +```go +r.HandleFunc("/products", ProductsHandler). + Host("www.example.com"). + Methods("GET"). + Schemes("http") +``` + +Routes are tested in the order they were added to the router. If two routes match, the first one wins: + +```go +r := mux.NewRouter() +r.HandleFunc("/specific", specificHandler) +r.PathPrefix("/").Handler(catchAllHandler) +``` + +Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". + +For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it: + +```go +r := mux.NewRouter() +s := r.Host("www.example.com").Subrouter() +``` + +Then register routes in the subrouter: + +```go +s.HandleFunc("/products/", ProductsHandler) +s.HandleFunc("/products/{key}", ProductHandler) +s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler) +``` + +The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. + +Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. + +There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: + +```go +r := mux.NewRouter() +s := r.PathPrefix("/products").Subrouter() +// "/products/" +s.HandleFunc("/", ProductsHandler) +// "/products/{key}/" +s.HandleFunc("/{key}/", ProductHandler) +// "/products/{key}/details" +s.HandleFunc("/{key}/details", ProductDetailsHandler) +``` + + +### Static Files + +Note that the path provided to `PathPrefix()` represents a "wildcard": calling +`PathPrefix("/static/").Handler(...)` means that the handler will be passed any +request that matches "/static/\*". This makes it easy to serve static files with mux: + +```go +func main() { + var dir string + + flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir") + flag.Parse() + r := mux.NewRouter() + + // This will serve files under http://localhost:8000/static/ + r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir)))) + + srv := &http.Server{ + Handler: r, + Addr: "127.0.0.1:8000", + // Good practice: enforce timeouts for servers you create! + WriteTimeout: 15 * time.Second, + ReadTimeout: 15 * time.Second, + } + + log.Fatal(srv.ListenAndServe()) +} +``` + +### Registered URLs + +Now let's see how to build registered URLs. + +Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example: + +```go +r := mux.NewRouter() +r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler). + Name("article") +``` + +To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: + +```go +url, err := r.Get("article").URL("category", "technology", "id", "42") +``` + +...and the result will be a `url.URL` with the following path: + +``` +"/articles/technology/42" +``` + +This also works for host and query value variables: + +```go +r := mux.NewRouter() +r.Host("{subdomain}.domain.com"). + Path("/articles/{category}/{id:[0-9]+}"). + Queries("filter", "{filter}"). + HandlerFunc(ArticleHandler). + Name("article") + +// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla" +url, err := r.Get("article").URL("subdomain", "news", + "category", "technology", + "id", "42", + "filter", "gorilla") +``` + +All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. + +Regex support also exists for matching Headers within a route. For example, we could do: + +```go +r.HeadersRegexp("Content-Type", "application/(text|json)") +``` + +...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` + +There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do: + +```go +// "http://news.domain.com/" +host, err := r.Get("article").URLHost("subdomain", "news") + +// "/articles/technology/42" +path, err := r.Get("article").URLPath("category", "technology", "id", "42") +``` + +And if you use subrouters, host and path defined separately can be built as well: + +```go +r := mux.NewRouter() +s := r.Host("{subdomain}.domain.com").Subrouter() +s.Path("/articles/{category}/{id:[0-9]+}"). + HandlerFunc(ArticleHandler). + Name("article") + +// "http://news.domain.com/articles/technology/42" +url, err := r.Get("article").URL("subdomain", "news", + "category", "technology", + "id", "42") +``` + +### Walking Routes + +The `Walk` function on `mux.Router` can be used to visit all of the routes that are registered on a router.

Here's how to do that alongside `mux`: + +```go +package main + +import ( + "context" + "flag" + "log" + "net/http" + "os" + "os/signal" + "time" + + "github.com/gorilla/mux" +) + +func main() { + var wait time.Duration + flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m") + flag.Parse() + + r := mux.NewRouter() + // Add your routes as needed + + srv := &http.Server{ + Addr: "0.0.0.0:8080", + // Good practice to set timeouts to avoid Slowloris attacks. + WriteTimeout: time.Second * 15, + ReadTimeout: time.Second * 15, + IdleTimeout: time.Second * 60, + Handler: r, // Pass our instance of gorilla/mux in. + } + + // Run our server in a goroutine so that it doesn't block. + go func() { + if err := srv.ListenAndServe(); err != nil { + log.Println(err) + } + }() + + c := make(chan os.Signal, 1) + // We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C) + // SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught. + signal.Notify(c, os.Interrupt) + + // Block until we receive our signal. + <-c + + // Create a deadline to wait for. + ctx, cancel := context.WithTimeout(context.Background(), wait) + defer cancel() + // Doesn't block if no connections, but will otherwise wait + // until the timeout deadline. + srv.Shutdown(ctx) + // Optionally, you could run srv.Shutdown in a goroutine and block on + // <-ctx.Done() if your application should wait for other services + // to finalize based on context cancellation. + log.Println("shutting down") + os.Exit(0) +} +``` + +### Middleware + +Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters. +Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking. + +Mux middlewares are defined using the de facto standard type: + +```go +type MiddlewareFunc func(http.Handler) http.Handler +``` + +Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers. + +A very basic middleware which logs the URI of the request being handled could be written as: + +```go +func loggingMiddleware(next http.Handler) http.Handler { + return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { + // Do stuff here + log.Println(r.RequestURI) + // Call the next handler, which can be another middleware in the chain, or the final handler. + next.ServeHTTP(w, r) + }) +} +``` + +Middlewares can be added to a router using `Router.Use()`: + +```go +r := mux.NewRouter() +r.HandleFunc("/", handler) +r.Use(loggingMiddleware) +``` + +A more complex authentication middleware, which maps session token to users, could be written as: + +```go +// Define our struct +type authenticationMiddleware struct { + tokenUsers map[string]string +} + +// Initialize it somewhere +func (amw *authenticationMiddleware) Populate() { + amw.tokenUsers["00000000"] = "user0" + amw.tokenUsers["aaaaaaaa"] = "userA" + amw.tokenUsers["05f717e5"] = "randomUser" + amw.tokenUsers["deadbeef"] = "user0" +} + +// Middleware function, which will be called for each request +func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler { + return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { + token := r.Header.Get("X-Session-Token") + + if user, found := amw.tokenUsers[token]; found { + // We found the token in our map + log.Printf("Authenticated user %s\n", user) + // Pass down the request to the next middleware (or final handler) + next.ServeHTTP(w, r) + } else { + // Write an error and stop the handler chain + http.Error(w, "Forbidden", http.StatusForbidden) + } + }) +} +``` + +```go +r := mux.NewRouter() +r.HandleFunc("/", handler) + +amw := authenticationMiddleware{} +amw.Populate() + +r.Use(amw.Middleware) +``` + +Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it. + +### Testing Handlers + +Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_. + +First, our simple HTTP handler: + +```go +// endpoints.go +package main + +func HealthCheckHandler(w http.ResponseWriter, r *http.Request) { + // A very simple health check. + w.WriteHeader(http.StatusOK) + w.Header().Set("Content-Type", "application/json") + + // In the future we could report back on the status of our DB, or our cache + // (e.g. Redis) by performing a simple PING, and include them in the response. + io.WriteString(w, `{"alive": true}`) +} + +func main() { + r := mux.NewRouter() + r.HandleFunc("/health", HealthCheckHandler) + + log.Fatal(http.ListenAndServe("localhost:8080", r)) +} +``` + +Our test code: + +```go +// endpoints_test.go +package main + +import ( + "net/http" + "net/http/httptest" + "testing" +) + +func TestHealthCheckHandler(t *testing.T) { + // Create a request to pass to our handler. We don't have any query parameters for now, so we'll + // pass 'nil' as the third parameter. + req, err := http.NewRequest("GET", "/health", nil) + if err != nil { + t.Fatal(err) + } + + // We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response. + rr := httptest.NewRecorder() + handler := http.HandlerFunc(HealthCheckHandler) + + // Our handlers satisfy http.Handler, so we can call their ServeHTTP method + // directly and pass in our Request and ResponseRecorder. + handler.ServeHTTP(rr, req) + + // Check the status code is what we expect. + if status := rr.Code; status != http.StatusOK { + t.Errorf("handler returned wrong status code: got %v want %v", + status, http.StatusOK) + } + + // Check the response body is what we expect. + expected := `{"alive": true}` + if rr.Body.String() != expected { + t.Errorf("handler returned unexpected body: got %v want %v", + rr.Body.String(), expected) + } +} +``` + +In the case that our routes have [variables](#examples), we can pass those in the request. We could write +[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple +possible route variables as needed. + +```go +// endpoints.go +func main() { + r := mux.NewRouter() + // A route with a route variable: + r.HandleFunc("/metrics/{type}", MetricsHandler) + + log.Fatal(http.ListenAndServe("localhost:8080", r)) +} +``` + +Our test file, with a table-driven test of `routeVariables`: + +```go +// endpoints_test.go +func TestMetricsHandler(t *testing.T) { + tt := []struct{ + routeVariable string + shouldPass bool + }{ + {"goroutines", true}, + {"heap", true}, + {"counters", true}, + {"queries", true}, + {"adhadaeqm3k", false}, + } + + for _, tc := range tt { + path := fmt.Sprintf("/metrics/%s", tc.routeVariable) + req, err := http.NewRequest("GET", path, nil) + if err != nil { + t.Fatal(err) + } + + rr := httptest.NewRecorder() + + // Need to create a router that we can pass the request through so that the vars will be added to the context + router := mux.NewRouter() + router.HandleFunc("/metrics/{type}", MetricsHandler) + router.ServeHTTP(rr, req) + + // In this case, our MetricsHandler returns a non-200 response + // for a route variable it doesn't know about. + if rr.Code == http.StatusOK && !tc.shouldPass { + t.Errorf("handler should have failed on routeVariable %s: got %v want %v", + tc.routeVariable, rr.Code, http.StatusOK) + } + } +} +``` + +## Full Example + +Here's a complete, runnable example of a small `mux` based server: + +```go +package main + +import ( + "net/http" + "log" + "github.com/gorilla/mux" +) + +func YourHandler(w http.ResponseWriter, r *http.Request) { + w.Write([]byte("Gorilla!\n")) +} + +func main() { + r := mux.NewRouter() + // Routes consist of a path and a handler function. + r.HandleFunc("/", YourHandler) + + // Bind to a port and pass our router in + log.Fatal(http.ListenAndServe(":8000", r)) +} +``` + +## License + +BSD licensed.

All rights reserved. +// Use of this source code is governed by a BSD-style +// license that can be found in the LICENSE file. + +/* +Package mux implements a request router and dispatcher. + +The name mux stands for "HTTP request multiplexer". Like the standard +http.ServeMux, mux.Router matches incoming requests against a list of +registered routes and calls a handler for the route that matches the URL +or other conditions. The main features are: + + * Requests can be matched based on URL host, path, path prefix, schemes, + header and query values, HTTP methods or using custom matchers. + * URL hosts, paths and query values can have variables with an optional + regular expression. + * Registered URLs can be built, or "reversed", which helps maintaining + references to resources. + * Routes can be used as subrouters: nested routes are only tested if the + parent route matches. This is useful to define groups of routes that + share common conditions like a host, a path prefix or other repeated + attributes. As a bonus, this optimizes request matching. + * It implements the http.Handler interface so it is compatible with the + standard http.ServeMux. + +Let's start registering a couple of URL paths and handlers: + + func main() { + r := mux.NewRouter() + r.HandleFunc("/", HomeHandler) + r.HandleFunc("/products", ProductsHandler) + r.HandleFunc("/articles", ArticlesHandler) + http.Handle("/", r) + } + +Here we register three routes mapping URL paths to handlers. This is +equivalent to how http.HandleFunc() works: if an incoming request URL matches +one of the paths, the corresponding handler is called passing +(http.ResponseWriter, *http.Request) as parameters. + +Paths can have variables. They are defined using the format {name} or +{name:pattern}. If a regular expression pattern is not defined, the matched +variable will be anything until the next slash. For example: + + r := mux.NewRouter() + r.HandleFunc("/products/{key}", ProductHandler) + r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler) + r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler) + +Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: + + r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler) + +The names are used to create a map of route variables which can be retrieved +calling mux.Vars(): + + vars := mux.Vars(request) + category := vars["category"] + +Note that if any capturing groups are present, mux will panic() during parsing. To prevent +this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to +"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably +when capturing groups were present. + +And this is all you need to know about the basic usage. More advanced options +are explained below. + +Routes can also be restricted to a domain or subdomain. Just define a host +pattern to be matched. They can also have variables: + + r := mux.NewRouter() + // Only matches if domain is "www.example.com". + r.Host("www.example.com") + // Matches a dynamic subdomain. + r.Host("{subdomain:[a-z]+}.domain.com") + +There are several other matchers that can be added. To match path prefixes: + + r.PathPrefix("/products/") + +...or HTTP methods: + + r.Methods("GET", "POST") + +...or URL schemes: + + r.Schemes("https") + +...or header values: + + r.Headers("X-Requested-With", "XMLHttpRequest") + +...or query values: + + r.Queries("key", "value") + +...or to use a custom matcher function: + + r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool { + return r.ProtoMajor == 0 + }) + +...and finally, it is possible to combine several matchers in a single route: + + r.HandleFunc("/products", ProductsHandler). + Host("www.example.com"). + Methods("GET"). + Schemes("http") + +Setting the same matching conditions again and again can be boring, so we have +a way to group several routes that share the same requirements. +We call it "subrouting". + +For example, let's say we have several URLs that should only match when the +host is "www.example.com". Create a route for that host and get a "subrouter" +from it: + + r := mux.NewRouter() + s := r.Host("www.example.com").Subrouter() + +Then register routes in the subrouter: + + s.HandleFunc("/products/", ProductsHandler) + s.HandleFunc("/products/{key}", ProductHandler) + s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler) + +The three URL paths we registered above will only be tested if the domain is +"www.example.com", because the subrouter is tested first. This is not +only convenient, but also optimizes request matching. You can create +subrouters combining any attribute matchers accepted by a route. + +Subrouters can be used to create domain or path "namespaces": you define +subrouters in a central place and then parts of the app can register its +paths relatively to a given subrouter. + +There's one more thing about subroutes. When a subrouter has a path prefix, +the inner routes use it as base for their paths: + + r := mux.NewRouter() + s := r.PathPrefix("/products").Subrouter() + // "/products/" + s.HandleFunc("/", ProductsHandler) + // "/products/{key}/" + s.HandleFunc("/{key}/", ProductHandler) + // "/products/{key}/details" + s.HandleFunc("/{key}/details", ProductDetailsHandler) + +Note that the path provided to PathPrefix() represents a "wildcard": calling +PathPrefix("/static/").Handler(...) means that the handler will be passed any +request that matches "/static/*". This makes it easy to serve static files with mux: + + func main() { + var dir string + + flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir") + flag.Parse() + r := mux.NewRouter() + + // This will serve files under http://localhost:8000/static/ + r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir)))) + + srv := &http.Server{ + Handler: r, + Addr: "127.0.0.1:8000", + // Good practice: enforce timeouts for servers you create! + WriteTimeout: 15 * time.Second, + ReadTimeout: 15 * time.Second, + } + + log.Fatal(srv.ListenAndServe()) + } + +Now let's see how to build registered URLs. + +Routes can be named. All routes that define a name can have their URLs built, +or "reversed". We define a name calling Name() on a route. For example: + + r := mux.NewRouter() + r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler). + Name("article") + +To build a URL, get the route and call the URL() method, passing a sequence of +key/value pairs for the route variables. For the previous route, we would do: + + url, err := r.Get("article").URL("category", "technology", "id", "42") + +...and the result will be a url.URL with the following path: + + "/articles/technology/42" + +This also works for host and query value variables: + + r := mux.NewRouter() + r.Host("{subdomain}.domain.com"). + Path("/articles/{category}/{id:[0-9]+}"). + Queries("filter", "{filter}"). + HandlerFunc(ArticleHandler). + Name("article") + + // url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla" + url, err := r.Get("article").URL("subdomain", "news", + "category", "technology", + "id", "42", + "filter", "gorilla") + +All variables defined in the route are required, and their values must +conform to the corresponding patterns. These requirements guarantee that a +generated URL will always match a registered route -- the only exception is +for explicitly defined "build-only" routes which never match. + +Regex support also exists for matching Headers within a route. For example, we could do: + + r.HeadersRegexp("Content-Type", "application/(text|json)") + +...and the route will match both requests with a Content-Type of `application/json` as well as +`application/text` + +There's also a way to build only the URL host or path for a route: +use the methods URLHost() or URLPath() instead. For the previous route, +we would do: + + // "http://news.domain.com/" + host, err := r.Get("article").URLHost("subdomain", "news") + + // "/articles/technology/42" + path, err := r.Get("article").URLPath("category", "technology", "id", "42") + +And if you use subrouters, host and path defined separately can be built +as well: + + r := mux.NewRouter() + s := r.Host("{subdomain}.domain.com").Subrouter() + s.Path("/articles/{category}/{id:[0-9]+}"). + HandlerFunc(ArticleHandler). + Name("article") + + // "http://news.domain.com/articles/technology/42" + url, err := r.Get("article").URL("subdomain", "news", + "category", "technology", + "id", "42") + +Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters.

configuration populated you can create a container: + +```go +container, err := factory.Create("container-id", config) +if err != nil { + logrus.Fatal(err) + return +} +``` + +To spawn bash as the initial process inside the container and have the +processes pid returned in order to wait, signal, or kill the process: + +```go +process := &libcontainer.Process{ + Args: []string{"/bin/bash"}, + Env: []string{"PATH=/bin"}, + User: "daemon", + Stdin: os.Stdin, + Stdout: os.Stdout, + Stderr: os.Stderr, +} + +err := container.Run(process) +if err != nil { + container.Destroy() + logrus.Fatal(err) + return +} + +// wait for the process to finish. +_, err := process.Wait() +if err != nil { + logrus.Fatal(err) +} + +// destroy the container. +container.Destroy() +``` + +Additional ways to interact with a running container are: + +```go +// return all the pids for all processes running inside the container. +processes, err := container.Processes() + +// get detailed cpu, memory, io, and network statistics for the container and +// it's processes. +stats, err := container.Stats() + +// pause all processes inside the container. +container.Pause() + +// resume all

integrates [CRIU](http://criu.org/) for checkpointing and restoring containers. +This let's you save the state of a process running inside a container to disk, and then restore +that state into a new process, on the same machine or on another machine. + +`criu` version 1.5.2 or higher is required to use checkpoint and restore. +If you don't already have `criu` installed, you can build it from source, following the +[online instructions](http://criu.org/Installation). `criu` is also installed in the docker image +generated when building libcontainer with docker. + + +## Copyright and

This sync is +done via a pipe ( specified in the runtime section below ) that the container's +init process will block waiting for the parent to finish setup. + +### IntelRdt + +Intel platforms with new Xeon CPU support Intel Resource Director Technology +(RDT). Cache Allocation Technology (CAT) is a sub-feature of RDT, which +currently supports L3 cache resource allocation. + +This feature provides a way for the software to restrict cache allocation to a +defined 'subset' of L3 cache which may be overlapping with other 'subsets'. +The different subsets are identified by class of service (CLOS) and each CLOS +has a capacity bitmask (CBM). + +It can be used to handle L3 cache resource allocation for containers if +hardware and kernel support Intel RDT/CAT. + +In Linux 4.10 kernel or newer, the interface is defined and exposed via +"resource control" filesystem, which is a "cgroup-like" interface. + +Comparing with cgroups, it has similar process management lifecycle and +interfaces in a container. But unlike cgroups' hierarchy, it has single level +filesystem layout. + +Intel RDT "resource control" filesystem hierarchy: +``` +mount -t resctrl resctrl /sys/fs/resctrl +tree /sys/fs/resctrl +/sys/fs/resctrl/ +|-- info +| |-- L3 +| |-- cbm_mask +| |-- min_cbm_bits +| |-- num_closids +|-- cpus +|-- schemata +|-- tasks +|-- + |-- cpus + |-- schemata + |-- tasks + +``` + +For runc, we can make use of `tasks` and `schemata` configuration for L3 cache +resource constraints. + +The file `tasks` has a list of tasks that belongs to this group (e.g., +" group). Tasks can be added to a group by writing the task ID +to the "tasks" file (which will automatically remove them from the previous +group to which they belonged). New tasks created by fork(2) and clone(2) are +added to the same group as their parent. If a pid is not in any sub group, it +is in root group. + +The file `schemata` has allocation masks/values for L3 cache on each socket, +which contains L3 cache id and capacity bitmask (CBM). +``` + Format: "L3:=;=;..." +``` +For example, on a two-socket machine, L3's schema line could be `L3:0=ff;1=c0` +Which means L3 cache id 0's CBM is 0xff, and L3 cache id 1's CBM is 0xc0. + +The valid L3 cache CBM is a *contiguous bits set* and number of bits that can +be set is less than the max bit. The max bits in the CBM is varied among +supported Intel Xeon platforms. In Intel RDT "resource control" filesystem +layout, the CBM in a group should be a subset of the CBM in root. Kernel will +check if it is valid when writing. e.g., 0xfffff in root indicates the max bits +of CBM is 20 bits, which mapping to entire L3 cache capacity. Some valid CBM +values to set in a group: 0xf, 0xf0, 0x3ff, 0x1f00 and etc. + +For more information about Intel RDT/CAT kernel interface: +https://www.kernel.org/doc/Documentation/x86/intel_rdt_ui.txt + +An example for runc: +``` +Consider a two-socket machine with two L3 caches where the default CBM is +0xfffff and the max CBM length is 20 bits. With this configuration, tasks +inside the container only have access to the "upper" 80% of L3 cache id 0 and +the "lower" 50% L3 cache id 1: + +"linux": { + "intelRdt": { + "l3CacheSchema": "L3:0=ffff0;1=3ff" + } +} +``` + +### Security + +The standard set of Linux capabilities that are set in a container +provide a good default for security and flexibility for the applications. + + +| Capability | Enabled | +| -------------------- | ------- | +| CAP_NET_RAW | 1 | +| CAP_NET_BIND_SERVICE | 1 | +| CAP_AUDIT_READ | 1 | +| CAP_AUDIT_WRITE | 1 | +| CAP_DAC_OVERRIDE | 1 | +| CAP_SETFCAP | 1 | +| CAP_SETPCAP | 1 | +| CAP_SETGID | 1 | +| CAP_SETUID | 1 | +| CAP_MKNOD | 1 | +| CAP_CHOWN | 1 | +| CAP_FOWNER | 1 | +| CAP_FSETID | 1 | +| CAP_KILL | 1 | +| CAP_SYS_CHROOT | 1 | +| CAP_NET_BROADCAST | 0 | +| CAP_SYS_MODULE | 0 | +| CAP_SYS_RAWIO | 0 | +| CAP_SYS_PACCT | 0 | +| CAP_SYS_ADMIN | 0 | +| CAP_SYS_NICE | 0 | +| CAP_SYS_RESOURCE | 0 | +| CAP_SYS_TIME | 0 | +| CAP_SYS_TTY_CONFIG | 0 | +| CAP_AUDIT_CONTROL | 0 | +| CAP_MAC_OVERRIDE | 0 | +| CAP_MAC_ADMIN | 0 | +| CAP_NET_ADMIN | 0 | +| CAP_SYSLOG | 0 | +| CAP_DAC_READ_SEARCH | 0 | +| CAP_LINUX_IMMUTABLE | 0 | +| CAP_IPC_LOCK | 0 | +| CAP_IPC_OWNER | 0 | +| CAP_SYS_PTRACE | 0 | +| CAP_SYS_BOOT | 0 | +| CAP_LEASE | 0 | +| CAP_WAKE_ALARM | 0 | +| CAP_BLOCK_SUSPEND | 0 | + + +Additional security layers like [apparmor](https://wiki.ubuntu.com/AppArmor) +and [selinux](http://selinuxproject.org/page/Main_Page) can be used with +the containers.

This is accomplished by creating +a pipe that is passed to the container's init. When the init process first spawns +it will block on its side of the pipe until the parent closes its side. This +allows the parent to have time to set the new process inside a cgroup hierarchy +and/or write any uid/gid mappings required for user namespaces. +The pipe is passed to the init process via FD 3. + +The application consuming libcontainer should be compiled statically. libcontainer +does not define any init process and the arguments provided are used to `exec` the +process inside the application. There should be no long running init within the +container spec. + +If a pseudo tty is provided to a container it will open and `dup2` the console +as the container's STDIN, STDOUT, STDERR as well as mounting the console +as `/dev/console`. + +An extra set of mounts are provided to a container and setup for use. A container's +rootfs can contain some non portable files inside that can cause side effects during +execution of a process. These files are usually created and populated with the container +specific information via the runtime. + +**Extra runtime files:** +* /etc/hosts +* /etc/resolv.conf +* /etc/hostname +* /etc/localtime + + +#### Defaults + +There are a few defaults that can be overridden by users, but in their omission +these apply to processes within a container. + +| Type | Value | +| ------------------- | ------------------------------ | +| Parent Death Signal | SIGKILL | +| UID | 0 | +| GID | 0 | +| GROUPS | 0, NULL | +| CWD | "/" | +| $HOME | Current user's home dir or "/" | +| Readonly rootfs | false | +| Pseudo TTY | false | + + +## Actions + +After a container is created there is a standard set of actions that can +be done to the container.

Any binaries to be +executed must be accessible within the container's rootfs. + +The started process will run inside the container's rootfs. Any changes +made by the process to the container's filesystem will persist after the +process finished executing. + +The started process will join all the container's existing namespaces. When the +container is paused, the process will also be paused and will resume when +the container is unpaused. The started process will only run when the container's +primary process (PID 1) is running, and will not be restarted when the container +is restarted. + +#### Planned additions + +The started process will have its own cgroups nested inside the container's +cgroups. This is used for process tracking and optionally resource allocation +handling for the new process. Freezer cgroup is required, the rest of the cgroups +are optional. The process executor must place its pid inside the correct +cgroups before starting the process. This is done so that no child processes or +threads can escape the cgroups. + +When the process is stopped, the process executor will try (in a best-effort way) +to stop all its children and remove the sub-cgroups. diff --git a/vendor/github.com/opencontainers/runc/libcontainer/apparmor/apparmor.go b/vendor/github.com/opencontainers/runc/libcontainer/apparmor/apparmor.go new file mode 100644

This provides us the ability to `setns` on +existing namespaces and avoid the issues that the Go runtime has with multiple +threads. This constructor will be called if this package is registered, +imported, in your go application. + +The `nsenter` package will `import "C"` and it uses [cgo](https://golang.org/cmd/cgo/) +package. In cgo, if the import of "C" is immediately preceded by a comment, that comment, +called the preamble, is used as a header when compiling the C parts of the package. +So every time we import package `nsenter`, the C code function `nsexec()` would be +called. And package `nsenter` is now only imported in `main_unix.go`, so every time +before we call `cmd.Start` on linux, that C code would run. + +Because `nsexec()` must be run before the Go runtime in order to use the +Linux kernel namespace, you must `import` this library into a package if +you plan to use `libcontainer` directly. Otherwise Go will not execute +the `nsexec()` constructor, which means that the re-exec will not cause +the namespaces to be joined. You can import it like this: + +```go +import _ "github.com/opencontainers/runc/libcontainer/nsenter" +``` + +`nsexec()` will first get the file descriptor number for the init pipe +from the environment variable `_LIBCONTAINER_INITPIPE` (which was opened +by the parent and kept open across the fork-exec of the `nsexec()` init +process). The init pipe is used to read bootstrap data (namespace paths, +clone flags, uid and gid mappings, and the console path) from the parent +process. `nsexec()` will then call `setns(2)` to join the namespaces +provided in the bootstrap data (if available), `clone(2)` a child process +with the provided clone flags, update the user and group ID mappings, do +some further miscellaneous setup steps, and then send the PID of the +child process to the parent of the `nsexec()` "caller".

Netlink +is the interface a user-space program in linux uses to communicate with +the kernel. It can be used to add and remove interfaces, set ip addresses +and routes, and configure ipsec. Netlink communication requires elevated +privileges, so in most cases this code needs to be run as root. Since +low-level netlink messages are inscrutable at best, the library attempts +to provide an api that is loosely modeled on the CLI provied by iproute2. +Actions like `ip link add` will be accomplished via a similarly named +function like AddLink(). This library began its life as a fork of the +netlink functionality in +[docker/libcontainer](https://github.com/docker/libcontainer) but was +heavily rewritten to improve testability, performance, and to add new +functionality like ipsec xfrm handling. + +## Local Build and Test ## + +You can use go get command: + + go get github.com/vishvananda/netlink + +Testing dependencies: + + go get github.com/vishvananda/netns + +Testing (requires root): + + sudo -E go test github.com/vishvananda/netlink + +## Examples ## + +Add a new bridge and add eth1 into it: + +```go +package main + +import ( + "net" + "github.com/vishvananda/netlink" +) + +func main() { + la := netlink.NewLinkAttrs() + la.Name = "foo" + mybridge := &netlink.Bridge{la}} + _ := netlink.LinkAdd(mybridge) + eth1, _ := netlink.LinkByName("eth1") + netlink.LinkSetMaster(eth1, mybridge) +} + +``` +Note `NewLinkAttrs` constructor, it sets default values in structure. For now +it sets only `TxQLen` to `-1`, so kernel will set default by itself. If you're +using simple initialization(`LinkAttrs{Name: "foo"}`) `TxQLen` will be set to +`0` unless you specify it like `LinkAttrs{Name: "foo", TxQLen: 1000}`. + +Add a new ip address to loopback: + +```go +package main + +import ( + "net" + "github.com/vishvananda/netlink" +) + +func main() { + lo, _ := netlink.LinkByName("lo") + addr, _ := netlink.ParseAddr("169.254.169.254/32") + netlink.AddrAdd(lo, addr) +} + +``` + +## Future Work ## + +Many pieces of netlink are not yet fully supported in the high-level +interface. Aspects of virtually all of the high-level objects don't exist. +Many of the underlying primitives are there, so its a matter of putting +the right fields into the high-level objects and making sure that they +are serialized and deserialized correctly in the Add and List methods. + +There are also a few pieces of low level netlink functionality that still +need to be implemented. Routing rules are not in place and some of the +more advanced link types. Hopefully there is decent structure and testing +in place to make these fairly straightforward to add. diff --git a/vendor/github.com/vishvananda/netlink/addr.go b/vendor/github.com/vishvananda/netlink/addr.go new file mode 100644 index 000000000000..9bbaf508e0c9 --- /dev/null +++ b/vendor/github.com/vishvananda/netlink/addr.go @@ -0,0 +1,43 @@ +package netlink + +import ( + "fmt" + "net" + "strings" +) + +// Addr represents an IP address from netlink.
