Jenkins Amazon ECR: no basic auth credentials

Question

I'm not able to push ocker images to Amazon ECR with Jenkins Pipeline: I always get no basic auth credentials :-(

Here is my setup:

• Jenkins 2.46.2
• Amazon ECR plugin 1.4
• I've added AWS credentials aws-jenkins to Jenkins (tested locally and successfully pushed to AWS ECR)
• I've printed /root/.dockercfg to debug auth in my Jenkinsfile

Jenkinsfile:

stage("Docker") {
  dir(path) {
    docker.build("my-image:latest")
  }
  docker.withRegistry("https://<my-aws-id>.dkr.ecr.eu-central-1.amazonaws.com", "ecr:eu-central-1:aws-jenkins") {
    sh "cat /root/.dockercfg" // debug
    docker.image("my-image:latest").push()
  }
}

Logs:

Any ideas?

Even that it seems logical that docker.withRegistry will perform a login to ECR at start and logout when done, it is not performed. Therefor you must install awscli and add ECR login command before you perform the push.

sh("eval \$(aws ecr get-login --no-include-email | sed 's|https://||')")
