Nexus Repository Helm Format

Huzzah! Helm is now part of Nexus Repository Manager. Version 3.21 includes the Helm plugin by default. The plugin source code is now in nexus-public in nexus-repository-helm.

Filing issues: Upgrade to the latest version of Nexus Repository Manager 3, to get the latest fixes and improvements, before filing any issues or feature requests at https://issues.sonatype.org/.

Upgrading: If you are using a version prior to 3.21 and upgrade to a newer version you will not be able to install the community plugin. No other changes are required and your existing data will remain intact.

Developing

Requirements

• Apache Maven 3.3.3+
• Java 8
• Network access to https://repository.sonatype.org/content/groups/sonatype-public-grid

Also, there is a good amount of information available at Bundle Development

Building

To build the project and generate the bundle use Maven

mvn clean package

If everything checks out, the bundle for Helm should be available in the target folder.

In the examples below, substitute <helm_version> with the current version of the helm format plugin.

Build with Docker

docker build -t nexus-repository-helm:<helm_version> .

Run as a Docker container

docker run -d -p 8081:8081 --name nexus nexus-repository-helm:<helm_version>

For further information like how to persist volumes check out the GitHub repo for our official image.

After allowing some time to spin up, the application will be available from your browser at http://localhost:8081.

To read the generated admin password for your first login to the web UI, you can use the command below against the running docker container:

  docker exec -it nexus cat /nexus-data/admin.password && echo

Once logged into the application UI as admin using the generated password, you may also want to turn on "Enable anonymous access" when prompted by the setup wizard.

Installing The Plugin

In Nexus Repository Manager 3.21+ Helm format is already included. So there is no need to install it. But if you want to reinstall the plugin with your improvements then following instructions will be useful.
Note: Using an unofficial version of the plugin is not supported by the Sonatype Support team.

Permanent Reinstall

• Copy the new bundle into <nexus_dir>/system/org/sonatype/nexus/plugins/nexus-repository-helm/<helm_version>/nexus-repository-helm-<helm_version>.jar

• Edit <nexus_dir>/system/org/sonatype/nexus/assemblies/nexus-cma-feature/3.x.y/nexus-cma-feature-3.x.y-features.xml changing helm to your build version (examples, the actual lines surrounding may vary):

        <feature version="3.a.b">nexus-repository-p2</feature>
        <feature version="<helm_version>">nexus-repository-helm</feature>
        <feature version="3.x.y.xy">nexus-repository-raw</feature>
    </feature>
  

  And

   <feature name="nexus-repository-helm" description="org.sonatype.nexus.plugins:nexus-repository-helm" version="<helm_version>">
       <details>org.sonatype.nexus.plugins:nexus-repository-helm</details>
       <bundle>mvn:org.sonatype.nexus.plugins/nexus-repository-helm/<helm_version></bundle>
   </feature>
  

This will cause the plugin to be loaded and started with each startup of Nexus Repository Manager.

NOTE: The file location changed in version 3.21. For older versions, edit these files:

• If you are using OSS edition, make these mods in: <nexus_dir>/system/com/sonatype/nexus/assemblies/nexus-oss-feature/3.x.y/nexus-oss-feature-3.x.y-features.xml
• If you are using PRO edition, make these mods in: <nexus_dir>/system/com/sonatype/nexus/assemblies/nexus-pro-feature/3.x.y/nexus-pro-feature-3.x.y-features.xml

Additionally, prior to 3.21 the lines did not exist so they'd need to be added instead of edited.

The Fine Print

Starting from version 3.21+ the Helm plugin is supported by Sonatype, but still is a contribution of ours to the open source community (read: you!)

Phew, that was easier than I thought. Last but not least of all:

Have fun creating and using this plugin and the Nexus platform, we are glad to have you here!
