v0.31.0

Release 0.31.0

What's New

  • Rate limited for model changes

Rate Limiter for Model Changes

To prevent the controller from being overwhelmed by a flood of changes, a rate limiter
can be enabled in the configuration file. A maximum number of queued changes can also
be configured. The rate limited is disabled by default for now. If not specified the
default number of queued changes is 100.

When the rate limit is hit, an error will be returned. If the request came in from
the REST API, the response will use HTTP status code 429 (too many requests).

The OpenAPI specs have been updated, so if you're using a generated client to make
REST calls, it's recommened that you regenerate your client.

commandRateLimiter:
    enabled:   true
    maxQueued: 100

If the rate limiter is enabled, the following metrics will be produced:

  • command.limiter.queued_count - guage of the current number of queued operations
  • command.limiter.work_timer - timer for operations. Includes the following:
    • A histogram of how long operations take to complete
    • A meter showing that rate at which operations are executed
    • A count of how many operations have been executed

What's New

  • ziti edge quickstart
  • Edge SDK terminator improvements
  • host.v1 and host.v2 connectTimeout/connectTimeoutSeconds
  • edge/fabric merge

ziti edge quickstart

  • ziti edge quickstart](#1298). You can now download
    the ziti CLI and have a functioning network with just one command. The network it creates is
    ephemeral and is intended to be torn down when the process exits. It is intended for quick
    evaluation and testing of an overlay network. It supports the following flags:

        --already-initialized     Specifies the PKI does not need to be created and the db does not need to be initialized. Recommended to be combined with --home. If --home is not specified the environment will be destroyed on shutdown! default: false
    --ctrl-address string     Sets the advertised address for the control plane and API
    --ctrl-port int16         Sets the port to use for the control plane and API
-h, --help                    help for quickstart
    --home string             Sets the directory the environment should be installed into. Defaults to a temporary directory. If specified, the environment will not be removed on exit.
-p, --password string         Password to use for authenticating to the Ziti Edge Controller. default: admin
    --router-address string   Sets the advertised address for the integrated router
    --router-port int16       Sets the port to use for the integrated router
-u, --username string         Username to use when creating the Ziti Edge Controller. default: admin

    Example Usage:

    ziti edge quickstart \
  --ctrl-address potato \
  --ctrl-port 12345 \
  --router-address avacado \
  --router-port 23456 \
  --home $HOME/.ziti/pet-ziti \
  --already-initialized \
  --username someOtherUsername \
  --password someOtherPassword

Edge SDK Terminator Improvements

There was a race condition in edge sdk terminator handling, where if sdk noticed a broken connection
before the router did, it would reconnect and rebind while the router still though it had the old
connection and old binding. Because we were using the session token to key terminator state in the
router, the new terminator information would overwrite the old terminator information in the router.
However, in the controller, the information wouldn't get overridden, since we use a UUID to key
things in the controller. When the router noticed the old connection was gone it would try to clean
things up, but since the state had been overwritten, it couldn't and the controller would be left
with an orphaned terminator.

The router now uses a UUID as well so there shouldn't be any more orphaned terminators.

host.v1/host.v2 change

The host.v2 config type was mostly a collection of host.v1 instances. However, there was a one small
difference. The host.v1 type had connectTimeoutSeconds in listenOptions, where host.v2
had connectTimeout, defined as a duration.

To bring them into alignment, both attributes are now supported in both config types.
However, connectTimeout will take precedence if both are present. connectTimeout is not yet
supported by all tunnelers. The following still need to be updated:

  • ziti-edge-tunnel
  • Desktop Edge for Windows
  • Desktop Edge for Mac
  • Mobile Edge for Android
  • Mobile Edge for IOS

Once it is supported, we will deprecate connectTimeoutSeconds with a lengthy deprecation period.
At the end of the deprecation period we will migrate any remaining connectTimeoutSeconds values
to connectTimeout.

Edge and Fabric Merges

The code from the fabric and edge repositories has been merged into the ziti repository. Once issues have been migrated, those two projects will be archived.

v0.30.2

Release 0.30.2

What's New

  • Identity type consolidation
  • HTTP Connect Proxy support for control channel and links

Identity Type Consolidation

Prior to this release there were four identity types:

  • User
  • Service
  • Device
  • Router

Of these four types, only Router has any functional purpose. Given that, the other three have been merged into
a single Default identity type. Since Router identities can only be created by the system, it's no longer
necesary to specify the identity type when creating identities.

The identity type may still be provided, but a deprecation warning will be emitted.

Backwards Compatibility

Existing non-Router identities will be migrated to the Default identity type. If an identity type other
than Default is provided when creating an identity, it will be coerced to the Default type. Existing
code may have issues with the new identity type being returned.

HTTP Connect Proxy support

Routers may now specify a proxy configuation which will be used when establishing connections to controllers
and data links to other routers. At this point only HTTP Connect Proxies with no authentication required are
supported.

Example router config:

proxy:
  type: http
  address: localhost:3128

Release 0.30.0

What's New

  • Link management is now delegated to routers
  • Controller and routers can operate with a single listening port

Link Management Updates

Previously, the controller would do its best to determine where links needed to be established.
It would send messages to the routers, telling them which addresses to dial on other routes.
The routers would in turn let the controller know if link establishment was successful or
if the router already had a link to the given endpoint.

With this release, the controller will only let routers know which routers exist, whether they
are currently connected to the controller, and what link listeners they are advertising. The
routers will now decide which links to make and let the controllers know as links are created
and broken.

Link Groups

Both dialers and listeners can now specify a set of groups. If no groups are specified, the
dialer or listener will be placed in the default group. Dialers will only attempt to dial
listeners who have at least one group in common with them.

Failed Links

Previously when a link failed, the controller would show it in the link list as failed for a time
before removing it. Now failed links are removed immediately. There are existing link events for
link creation and link failure which can be used for forensics.

Duplicate Links

There is a new link status Duplicate used when a router receives a link request and determines
that it's a duplicate of an existing link. This happens when two routers both have listeners
and dialers. They will often dial each other at the same time, resulting in a duplicate link.

Compatibility

If you use a 0.30+ controller with older routers, the controller will still do link calculation
and send dial messages, as long as the enableLegacyLinkMgmt setting is set to true.

If you use a pre 0.30.0 controller with newer routers, the new routers will still accept the
dial messages.

New Configuration

Controller

The controller has three new options:

network:
    routerMessaging:
        queueSize: 100
        maxWorkers: 100
    enableLegacyLinkMgmt: true

When a router connects or disconnects from the controller, we send two sets of updates.

  1. If a router has connected we send it the the state of the other routers
  2. We send all the other routers the updated state of the connecting/disconnecting router

These messages are sent using a worker pool. The size of the queue feeding the worker pool is controlled with
routerMessaging.queueSize. The max size of the worker pool is controlled used the routerMessaging.maxWorkers
option.

  • queueSize
    • Min value: 0
    • Max value: 1,000,000
    • Default: 100
  • maxWorkers
    • Min value: 1
    • Max value: 10,000
    • Default: 100

If you have routers older than 0.30.0, the controller will calculate which links to dial. This can be disabled
by setting enableLegacyLinkMgmt to false. This setting currently defaults to true, but will default to false
in a future release. In a subsequent release this functionality will be removed all together.

Router

The router has new configuration options for link dialing.

link:
   dialers:
       - binding: transport
         groups: 
             - public
             - vpc1234
         healthyDialBackoff:
             retryBackoffFactor: 1.5
             minRetryInterval: 5s
             maxRetryInterval: 5m
         unhealthyDialBackoff:
             retryBackoffFactor: 10
             minRetryInterval: 1m
             maxRetryInterval: 1h
    listeners:
        - binding: transport
          groups: vpc1234

Groups

See above for a description of link groups work.

Default value: default

Dial Back-off

Dialers can be configured with custom back-off behavior. Each dialer has a back-off policy for dialing
healthy routers (those that are connected to a controller) and a separate policy for unhealthy routers.

The back-off policies have the following attributes:

  • minRetryInterval - duration specifying the minimum time between dial attempts
  • maxRetryInterval - duration specifying the maximum time between dial attempts
  • retryBackoffFactor - factor by which to increase the retry interval between failed dial attempts
    • Min value: 1
    • Max value: 100
    • Default: 1.5 for healthy, 100 for unhealthy

Single Port/ALPN Changes

Ziti Controller and Routers can operate with a single open port. In order to implement this feature we use
ALPN (Application Layer Protocol Negotiation)
TLS extension. It allows TLS client to request and TLS server to select appropriate application protocol handler during
TLS handshake.

Protocol Details

The following protocol identifiers are defined:

id purpose
ziti-ctrl Control plane connections
ziti-link Fabric link connections
ziti-edge Client SDK connection to Edge Routers

Standard HTTP protocol identifiers (h2, http/1.1) are used for Controller REST API and Websocket listeners.

Backward Compatibility

This feature is designed to be backward compatible with SDK clients: older client will still be able to connect without
requesting ziti-edge protocol.

Breaking

Older routers won't be able to establish control channel or fabric links with updated network.
However, newer Edge Routers should be able to join older network in some circumstances -- only outbound links from new Routers would work.

v0.29.0

Release 0.29.0

What's New

Deprecated Binary Removal

This release removes the following deprecated binaries from the release archives.

  • ziti-controller - replaced by ziti controller
  • ziti-router - replaced by ziti router
  • ziti-tunnel - replaced by ziti tunnel

The release archives now only contain the ziti executable. This executable is now at the root of the archive instead of nested under a ziti directory.

Ziti CLI Demo Consolidation

The ziti CLI functions under ziti learn, namely ziti learn demo and ziti learn tutorial have been consolidated under ziti demo.

Continued Quickstart Changes

The quickstart continues to evolve. A breaking change has occurred as numerous environment variables used to customize the quickstart
have changed again. A summary of changes is below

  • All ZITI_EDGE_ROUTER_ variables have been changed to just ZITI_ROUTER_.
    • ZITI_EDGE_ROUTER_NAME -> ZITI_ROUTER_NAME
    • ZITI_EDGE_ROUTER_PORT -> ZITI_ROUTER_PORT
    • ZITI_EDGE_ROUTER_ADVERTISED_HOST -> ZITI_ROUTER_ADVERTISED_HOST
    • ZITI_EDGE_ROUTER_IP_OVERRIDE -> ZITI_ROUTER_IP_OVERRIDE
    • ZITI_EDGE_ROUTER_ENROLLMENT_DURATION -> ZITI_ROUTER_ENROLLMENT_DURATION
    • ZITI_EDGE_ROUTER_ADVERTISED_HOST -> ZITI_ROUTER_ADVERTISED_HOST
    • ZITI_EDGE_ROUTER_LISTENER_BIND_PORT -> ZITI_ROUTER_LISTENER_BIND_PORT
  • Additional variables have been added to support "alternative addresses" and "alternative PKI", for example
    to support using Let's Encrypt certificates easily in the quickstarts.
  • New variables were introduced to allow automatic generation of the alt_server_certs section. Both variables
    must be supplied for the variables to impact the configurations.
    • ZITI_PKI_ALT_SERVER_CERT - "Alternative server certificate. Must be specified with ZITI_PKI_ALT_SERVER_KEY"
    • ZITI_PKI_ALT_SERVER_KEY - "Key to use with the alternative server certificate. Must be specified with ZITI_PKI_ALT_SERVER_CERT"
  • New variables were introduced to allow one to override and customize the CSR section of routers which is used during enrollment.
    • ZITI_ROUTER_CSR_C - "The country (C) to use for router CSRs"
    • ZITI_ROUTER_CSR_ST - "The state/province (ST) to use for router CSRs"
    • ZITI_ROUTER_CSR_L - "The locality (L) to use for router CSRs"
    • ZITI_ROUTER_CSR_O - "The organization (O) to use for router CSRs"
    • ZITI_ROUTER_CSR_OU - "The organization unit to use for router CSRs"
    • ZITI_ROUTER_CSR_SANS_DNS - "The DNS name used in the CSR request"
  • New variable ZITI_CTRL_EDGE_BIND_ADDRESS allows controlling the IP the edge API uses
