Docker plugin fails to authenticate

XMLWordPrintable

      I am currently run a Jenkins server in Kubernetes. When I want to authenticate with docker the login won't work, neither dockerhub nor my own quay server.

      Here is a sample Jenkinsfile that doesn't work.

      // Uses Declarative syntax to run commands inside a container.
pipeline {
    triggers {
        pollSCM("*/5 * * * *")
    }
    agent {
        kubernetes {
            yaml '''
apiVersion: v1
kind: Pod
spec:
  volumes:
    - name: docker-sock
      hostPath:
        path: /var/run/docker.sock
  containers:
  - name: docker
    image: docker:latest
    command:
    - cat
    tty: true
    volumeMounts:
    - mountPath: /var/run/docker.sock
      name: docker-sock
'''
            defaultContainer 'golang'
        }
    }
    stages {
        stage('Push') {
            steps {
                container('docker') {
                    sh "docker build -t quay.imanuel.dev/jenny-jinya/shopware-tools:$BUILD_NUMBER ."
                    withDockerRegistry(credentialsId: 'quay.imanuel.dev', url: 'https://quay.imanuel.dev') {
                        sh "docker push quay.imanuel.dev/jenny-jinya/shopware-tools:$BUILD_NUMBER"
                    }
                }
            }
        }
    }
}

      After changing it to this, the login and push work as expected

      // Uses Declarative syntax to run commands inside a container.
pipeline {
    triggers {
        pollSCM("*/5 * * * *")
    }
    agent {
        kubernetes {
            yaml '''
apiVersion: v1
kind: Pod
spec:
  volumes:
    - name: docker-sock
      hostPath:
        path: /var/run/docker.sock
  containers:
  - name: docker
    image: docker:latest
    command:
    - cat
    tty: true
    volumeMounts:
    - mountPath: /var/run/docker.sock
      name: docker-sock
'''
            defaultContainer 'golang'
        }
    }
    stages {
        stage('Push') {
            steps {
                container('docker') {
                    sh "docker build -t quay.imanuel.dev/jenny-jinya/shopware-tools:$BUILD_NUMBER ."
                    withCredentials([usernamePassword(credentialsId: 'quay.imanuel.dev', passwordVariable: 'DOCKER_PASS', usernameVariable: 'DOCKER_USER')]) {
                        sh "echo ${DOCKER_PASS} | docker login -u ${DOCKER_USER} --password-stdin quay.imanuel.dev"
                    }
                    sh "docker push quay.imanuel.dev/jenny-jinya/shopware-tools:$BUILD_NUMBER"
                }
            }
        }
    }
}

      The versions are as follows:

      Jenkins: Jenkins 2.365
      docker-workflow: 521.v1a_a_dd2073b_2e
