Adding tags to docker image from jenkins

Question

I have a jenkins instance (which actually runs inside docker) for my Continous Integration.

The jenkins server builds docker images on an external docker host, tests

Answer 1

As shown in this blog post you can add two tags with the push command like so:

stage('Push image') {
    docker.withRegistry('https://registry.hub.docker.com', 'docker-hub-credentials') {
        app.push("${env.BUILD_NUMBER}")
        app.push("latest")
    }
}

PS Mind you Jenkins folks if you're reading this a 3rd party blog post does NOT count as documentation. This could have been resolved MUCH quicker had this been properly documented.
