What is the image for?

The intended purpose of this image is for it to be used as a Jenkins agent. By using the installed features the user is able to create Jenkins pipelines that can trigger Maven commands that can build and install Java projects. An example of using this image as a Jenkins agent via Kubernetes can be seen below.

First, an example of configuring the pod template in yaml to create the agent.

jenkins:
  clouds:
    - kubernetes:
        name: "kubernetes"
        templates:
          - name: "image-builder-maven"
            label: "image-builder-maven"
            nodeUsageMode: NORMAL
            containers:
              - name: "image-maven"
                image: "ghcr.io/liatrio/image-builder-maven:${builder_images_version}"

And then specifying the agent in the Jenkinsfile for an example step.

stage('Build') {
  agent {
    label "image-builder-maven"
  }
  steps {
    container('image-maven') {
      sh "mvn --version"
      sh "mvn package"
    }
  }
}
