Jenkins test pipeline docker build + push

[Walter Heestermans]

Hi,

I'm new in Jenkins and trying to run a pipeline to get source from github, build docker image, test docker image and push image to local docker repository.

node {

    def app

    stage('Clone repository') {
        checkout scm
    }

    stage('Build image') {
        app = docker.build("test/hellonode")
    }

    stage('Test image') {
        app.inside {
            sh 'node --version'
        }
    }

    stage('Push image') {
        docker.withRegistry('http://test.xyz-europe.com', 'test-dtr') {
     /* app.push("${env.BUILD_NUMBER}") */
     app.push("latest")
        }
    }

}

Repository 'test/hellonode' is created inside the local docker repository.

The credentials 'test-dtr' are created inside Jenkins: Jenkins --> Credentials --> System --> Global credentials (unrestricted)

All stages goes fine, except the push. The push is initiated, but seems that the credentials are not taken, I don't see any docker login neither?

denied: requested access to the resource is denied

The reason seems to be that the login is not done or taken. same issues when I do the above push via command line and not executing a 'docker login test.xyz-europe.com' first

What do I misconfigured? can somebody advise me here?

Regards
