Test a build

To run docker commands inside a jenkins agent you will need a custom jenkins agent with docker-in-docker working. Take a look and build the docker file in ./dockerfiles/jenkins-agent Push it to a registry and use it instead of above configured * Docker Image: jenkins/jnlp-slave If you do not use the custom image, the below pipeline will not work because default * Docker Image: jenkins/jnlp-slave public image does not have docker ability.

• Add a Jenkins Pipeline

node('jenkins-slave') {
    
     stage('unit-tests') {
        sh(script: """
            docker run --rm alpine /bin/sh -c "echo hello world"
        """)
    }
}
