Puppet Module for Sonatype Nexus

Puppet Module For Nexus

Our friends at Atlassian have created an open-sourced Puppet module to help manage the configuration of Sonatype Nexus instances. Here’s the news directly from Peter Leschev, Senior Development Team Lead:

Developer, Peter LeschevThe Build Engineering team at Atlassian has been running Sonatype Nexus instances for a few years now. We use Nexus for storing our public and private artifacts on https://maven.atlassian.com/ (which receives 2.6 million requests/day), publishing to maven central and the various proxies that we have spread out across the world to support our build grid, and our global development teams.

Sonatype’s support has been absolutely fantastic when we’ve hit hairy scaling issues. We’re also big users of Puppet where we manage our infrastructure as code. We originally managed our Sonatype Nexus instances by getting Puppet to manage the various xml files in the ‘sonatype-work/nexus/conf’ directory. This option had a few problems:

  • The need to restart Nexus to make sure new XML configuration files are processed
  • Ephemeral changes (staging repositories, for example) are lost after a Puppet run
  • When Nexus changes XML configuration files, Puppet will overwrite them and restart Nexus
  • Using XML for configuration is so passé

Having Nexus & Puppet fight over control of the configuration files isn’t a fun experience. The other alternative is to use Puppet Augeas, which allows more intelligent management of XML content, but this approach still shares several disadvantages and has its own:

  • The need to restart Nexus to make sure new XML configuration files are processed
  • Have to manage and maintain XML configuration templates and files
  • Introduce additional complexity to Puppet manifests

Thankfully, Nexus comes with a REST API, and we’ve taken advantage of it in writing a Puppet module that aims to address all of the above disadvantages. We’ve now open sourced this Puppet module so you can use it to manage your own Nexus instances in a Puppet managed environment.

    Great to see that this module now has over 21,000 downloads (as of March 2015). Nice work and a great contribution to the Puppet and Nexus communities.
