Puppet Module for Sonatype Nexus 3 aims to offer native configuration of Nexus instances in Puppet. The module uses Nexus REST interface to manage configuration.
Nexus 3 does not have the XML configuration files in the sonatype-work/nexus/conf
directory as the previous versions.
It uses a binary local database to save its configurations.
The only current supported way to automate configurations is to use the REST API, uploading and executing groovy code.
At this point not all options covered by the admin configuration web page are covered by this module, but the module is designed to be easily extensible and pull requests are welcome.
It was based on the Atlassian nexus_puppet module for Nexus 2,
Puppet Module for Sonatype Nexus 3 allows configuration like this:
#manifest/.../config.pp
nexus3_repository { 'public':
label => 'Public Repository',
provider_type => 'maven2',
type => 'hosted',
policy => 'release',
}
The module doesn't have any dependencies on other Puppet modules. It is using Ruby libraries that are contained in the default Ruby 2.1+ installation, like:
- json
- erb
Starting on version 3.21.2 of Nexus, the scripting API is disabled by default, check this reference on how to enable it before be able to use this module.
First of all you need to create a configuration file $confdir/nexus3_rest.conf
(whereas $confdir
defaults to
/etc/puppet
):
#!yaml
---
# credentials of a user with administrative power
admin_username: admin
admin_password: secret
# the base url of the Nexus service to be managed
nexus_base_url: http://localhost:8081/
# the path for the script API
# nexus_script_api_path: /service/rest/v1/script # default value
# Certain operations may result in data loss. The following parameter(s) control if Puppet should perform those
# changes or not. Set the parameter to `false` to prevent Puppet from enforcing the change and cause the Puppet run to
# fail instead.
can_delete_repositories: false
# timeout in seconds for opening the connection to the Nexus service
# connection_open_timeout: 10
# timeout in seconds for reading the answer from the Nexus service
# connection_timeout: 10
# Number of retries before giving up on the health check and consider the service not running.
# health_check_retries: 50
# Timeout in seconds to wait between single health checks.
# health_check_timeout: 3
The configuration file will provide the module with the required information about where Nexus is listening and which credentials to use to enforce the configuration. Obviously it is recommended to manage the file within Puppet and limit the visibility to the root.
Any change is enforced through Nexus REST API. Hence, the Nexus service has to be running before any modification can
be made. In general, any ordering between the service { 'nexus': }
resource and resources provided by this module
should be made explicit in the Puppet manifest itself. This module doesn't express any autorequire dependency ('soft
dependency') on the service resource itself - this is up to the user of the Puppet module. However, any resource provided by this module
will wait a certain amount of time in order to give Nexus the chance to properly start up. The default timeout is 150
seconds and can be configured via the configuration file.
All resources are implemented as providers. This means that if you have a running Nexus instance you can simply inspect the current state with:
puppet resource <resource-name>
for example:
puppet resource nexus3_repository
and copy/paste the result into your manifest file.
To allow change the admin user password the module provides the nexus3_admin_password
resource.
It will take care of check if the password needs to be changed and do the proper requests using the old and the new passwords.
#!puppet
nexus3_admin_password { 'admin_password':
old_password => 'admin123',
password => '123admin',
}
As of Nexus version 3.17.0 the initial admin password is randomly generated and stored in the admin.password file on the server.
Changelog - Repository Manager 3.17.0
To automatically use that file to set the new password use the admin_password_file
parameter to point to it.
#!puppet
nexus3_admin_password { 'admin_password':
admin_password_file => '/opt/sonatype-work/nexus3/admin.password',
password => '123admin',
}
The global configuration has been decomposed into different resources. The following examples show how to use them.
To change the Email settings the module provides the nexus3_smtp_settings
resource.
#!puppet
nexus3_smtp_settings { 'global':
enabled => true,
host => 'mail.example.com',
port => 25,
username => 'jdoe',
password => 'keepitsecret',
from_address => 'nexus@example.com',
}
To change the Realms settings the module provides the nexus3_realm_settings
resource.
It allows to change the order of the realms used to authenticate the users.
#!puppet
nexus3_realm_settings { 'global':
names => ['NexusAuthenticatingRealm', 'NexusAuthorizingRealm', 'LdapRealm'],
}
To change the Anonymous user settings the module provides the nexus3_anonymous_settings
resource.
It allows to change the username and realm used when a non identified user tries to use the Nexus web site.
#!puppet
nexus3_anonymous_settings { 'global':
enabled => true,
realm => 'NexusAuthorizingRealm',
username => 'anonymous',
}
To change the HTTP(S) proxy settings the module provides the nexus3_http_settings
resource.
It allows to change the parameters used by nexus when doing an HTTP(S) request to an external server.
#!puppet

connection_user_agent => 'nexus3_useragent',
connection_timeout => 90,
connection_maximum_retries => 2,

]
}
The Nexus Routing Rule settings can be configured using the nexus3_routing_rule
resource:
#!puppet
nexus3_routing_rule { 'images':
description => 'Block all images',
ensure => 'present',
mode => 'BLOCK',
matchers => ['/.*.jpg', '/.*.svg', '/.*.gif'],
}
The Nexus Task settings can be configured using the nexus3_task
resource:
There are different kinds of tasks, each one requires a set of configurations.
The example will show only the common fields. The specific one can be determined looking the Task class code,
or manually configuring the Nexus 3 one first time and then running the puppet resource nexus3_task
command.
#!puppet
nexus3_task { 'Empty Trash':
enabled => true, # true (default) or false
type => 'script', # required, valid values: `blobstore.compact`, `blobstore.rebuildComponentDB`,
# `create.browse.nodes`, `db.backup`, `rebuild.asset.uploadMetadata`,
# `repository.docker.gc`, `repository.docker.upload-purge`,
# `repository.maven.publish-dotindex`, `repository.maven.purge-unused-snapshots`,
# `repository.maven.rebuild-metadata`, `repository.maven.remove-snapshots`,
# `repository.maven.unpublish-dotindex`, `repository.npm.reindex`,
# `repository.purge-unused`, `repository.rebuild-index`,
# `repository.storage-facet-cleanup`, `repository.yum.rebuild.metadata`,
# `script`, `security.purge-api-keys`, `tasklog.cleanup`
#
alert_email => 'ops@example.com', # optional; use `absent` (default) to disable the email notification
frequency => 'daily', # one of `manual` (default), `once`, `daily`, `weekly`, `monthly` or `advanced`
start_date => '2014-05-31',
start_time => '20:00',
cron_expression => '0 */10 * * * ?',
recurring_day => ['sunday', 'tuesday'],
# specific task fields
}
Notes:
- Date and times are base on the timezone that is used on the server running Nexus. As Puppet should normally run on same server this shouldn't cause any trouble. However, when using the web ui on a computer with a different timezone, the values shown there are relative to that timezone and can appear different.
- Be very careful with one-off tasks (
reoccurrence => 'once'
); due to the way Nexus works, it will reject any updates of the one-off task once the scheduled date has passed. This will cause you Puppet run to fail. You have been warned.
Due to the complexity of the resource it is strongly recommended to configure the task via the user interface and use
puppet resource
to generate the corresponding Puppet manifest.
Setting reoccurrence
to one of the following values requires to specify additional properties:
manual
- no further property requiredonce
-start_date
andstart_time
hourly
-start_date
andstart_time
daily
-start_date
andstart_time
weekly
-start_date
,start_time
andrecurring_day
(recurring_day
should be a day of the week, e.g.monday
,tuesday
, ...,sunday
)monthly
-start_date
,start_time
andrecurring_day
(recurring_day
should be a day of the month, e.g. 1, 2, .... 29, 30, 31 orlast
)advanced
-cron_expression
It is expected that start_date
matches YYYY-MM-DD
and start_time
match HH:MM
(including
leading zeros). The recurring_day
accepts multiple values as a list (e.g. [1, 2, 'last'])
.
Furthermore, you should keep your manifest clean and not specify properties that are not required (e.g. specify
cron_expression
for a manual
task).
The module has been tested to work with the following Puppet and Ruby versions:
- Ruby 2.1.9p490
and
- Puppet 4.5.1
Furthermore, the module has been tested with the following Nexus versions:
- Nexus OSS 3.1.0-04+ running on Ubuntu 16.04
- Nexus OSS 3.19.1-01 running on Ubuntu 18.04 (for the cleanup policy stuff)
Due to the limitation of the Nexus REST api it is not possible to retrieve the current value of a password. Hence, Puppet can only manage the existence of the password but won't notice when passwords change. Either way, passwords will be updated when attributes of the same resource change as well.
- Raise an issue
- Fork it
- Create your feature branch (
git checkout -b my-new-feature
) - Commit your changes (
git commit -am 'Add some feature'
) - Push to the branch (
git push origin my-new-feature
) - Create new pull request targeting master
The tests run now against a real Nexus3 Server.
It can be an ordinary server instance, but dummy objects will be created on it on every run, or can be executed against a server instance inside docker.
To build the Docker image run: ./docker/build.sh [NEXUS_VERSION, for instance, 3.40.1]
To execute the container in CI mode run: ./docker/run.sh true [NEXUS_VERSION, for instance, 3.40.1]
To execute the container in interactive mode run: ./docker/run.sh false [NEXUS_VERSION, for instance, 3.40.1] [container_name, for instance, nexus3-tests]
. Then enter on bash and run bundle exec rspec
.
