      Description

      Hello,

       

      When pulling an image using docker.withRegistry() and docker.image(), the path prefix in the registry is omitted.

      def remote = 'registry-1-docker-io-remote'
      def registry = "https://<myserver>/${remote}/"
      def image = 'couchbase/server:5.5.6'
      
      node {
          stage("login on ${registry} and pull ${image}") {
              docker.withRegistry(registry, 'IZ_USER'){
                  mavenImage = docker.image(image)
                  mavenImage.pull()
              }
          }
      }
      
      [Pipeline] withDockerRegistry
      $ docker login -u swb2-izu-jvt-poc -p ******** https://<myserver>/registry-1-docker-io-remote
      Login Succeeded
      [Pipeline] {
      [Pipeline] isUnix
      [Pipeline] sh
      + docker pull <myserver>/couchbase/server:5.5.6
      Error response from daemon: unknown: Not Found
      

      As you can see, the path part was omitted when pulling the image. It performed docker pull <myserver>/couchbase/server:5.5.6 instead of docker pull <myserver>/registry-1-docker-io-remote/couchbase/server:5.5.6

       

      I tried with and without the final /, and with a declarative pipeline too. The result was the same.

      pipeline {
        agent none
        stages {
          stage('login and pull') {
            agent {
              docker {
                image 'maven:3.6-jdk-8-slim'
                registryUrl 'https://<myserver>/registry-1-docker-io-remote'
                registryCredentialsId 'IZ_USER'
              }
            }
            steps {
              echo 'Hello, Maven'
              sh 'mvn --version'
            }
          }
        }
      }
      
      $ docker login -u swb2-izu-jvt-poc -p ******** https://<myserver>/registry-1-docker-io-remote
      Login Succeeded
      [Pipeline] {
      [Pipeline] isUnix
      [Pipeline] sh
      + docker inspect -f . maven:3.6-jdk-8-slim
      
      Error: No such object: maven:3.6-jdk-8-slim
      [Pipeline] isUnix
      [Pipeline] sh
      + docker inspect -f . <myserver>/maven:3.6-jdk-8-slim
      
      Error: No such object: <myserver>/maven:3.6-jdk-8-slim
      [Pipeline] isUnix
      [Pipeline] sh
      + docker pull <myserver>/maven:3.6-jdk-8-slim
      Error response from daemon: unknown: Not Found
      

       

      Pulling with sh and the Docker CLI works

      def remote = 'registry-1-docker-io-remote'
      def registry = "<myserver>/${remote}"
      def image = 'couchbase/server:5.5.6'
      
      node {
          withCredentials([usernamePassword(credentialsId: 'IZ_USER', usernameVariable: 'IZ_USERNAME', passwordVariable: 'IZ_PASSWORD')]) {
              stage("cleanup local image ${image}") {
                  try {
                      sh "docker rmi -f ${image}"
                  } catch(e) {
                      echo "Caught: ${e}"
                  } finally {
                      echo 'System should be clean'
                  }
              }
              stage("login on ${remote}") {
                  sh "docker login -u ${IZ_USERNAME} -p ${IZ_PASSWORD} ${registry}"
              }
              stage("pull ${image}"){
                  sh "docker pull ${registry}/${image}"
              }
          }
      }
