Docker Registry Artifact plugin

The docker registry artifact plugin provides a way to push and pull docker images on GoCD

Building the code base

To build the jar, run ./gradlew clean test assemble

Getting started

Requirements

  • GoCD Server 18.7+
  • Docker registry
  • Docker daemon

Installation

Build the plugin with ./gradlew clean test assemble

Copy the file build/libs/docker-registry-artifact-plugin-VERSION.jar to the GoCD server under ${GO_SERVER_DIR}/plugins/external and restart the server. The GO_SERVER_DIR is usually /var/lib/go-server on Linux and C:\Program Files\Go Server on Windows.

Configuration

There are three levels of configuration needed in order for publishing and fetching a docker image as an artifact.

Configure the Artifact Store

  1. Login to GoCD server as admin and navigate to Admin > Artifact Stores

  2. Click on Add to add the store details for the plugin.

    • Specify the store id
    • Choose the docker registry artifact plugin
    • Specify the Docker Registry Url
    • Specify username and password

Publish artifact config

  1. Navigate to the Artifacts tab under Stage > Job

  2. Choose artifact type External

    • Specify the artifact id.
    • Specify the store id of an existing artifact store
  3. Configure the build specific artifact details.

    • Optionally specify the Image and Tag. Usually, the Tag can be an environment variable that changes for every build. For example, the GO_PIPELINE_LABEL can be used to publish a versioned docker image.
    • Optionally specify the BuildFile. Specify a json file name. The format of the file should be {"image": "name", "tag": "tag pattern"}. The BuildFile option can be used if the Tag option cannot be specified for the tag pattern you want to use. The generation of this json file must be handled within the GoCD job.

Fetch artifact config

To pull an image from an upstream pipeline or stage, the following information is required:

  1. Specify a Pipeline Dependency material if you have an upstream pipeline you want to pull the docker image.
  2. Navigate to Tasks tab under Stage > Job
  3. Add a Fetch Artifact task
    • Choose artifact origin type External
    • Specify the pipeline, stage and job name.
    • Specify the artifact id of the external artifact that belongs to the upstream job
