Using a custom registry instead of default dockerhub registry

Question

I am using the docker plugin in jenkins for jenkins-docker integration, i am using a scripted pipeline in my project. I don't want to use the dockerhub which is the default registry that comes with the docker plugin.How do i configure to use a custom registry instead?

Answer 1

By default the "Docker pipeline" integrates assumes the default Docker Registry of Docker Hub.

In order to use a custom Docker Registry, users of Scripted Pipeline can wrap steps with the withRegistry() method, passing in the custom Registry URL, for example:
 

node {
    checkout scm

    docker.withRegistry('https://registry.example.com') {

        docker.image('my-custom-image').inside {
            sh 'make test'
        }
    }
}

For a Docker Registry which requires authentication, add a "Username/Password" Credentials item from the Jenkins home page and use the Credentials ID as a second argument to withRegistry():
 

node {
    checkout scm

    docker.withRegistry('https://registry.example.com', 'credentials-id') {

        def customImage = docker.build("my-image:${env.BUILD_ID}")

        /* Push the container to the custom Registry */
        customImage.push()
    }
}
