Jenkins無法使用docker構建

我正在嘗試使用 Jenkins 和 Docker 構建我的 Maven 專案。

我準備在我的存盤庫中跟蹤 Jenkinsfile。

pipeline {
    agent none
    stages {
        stage('3-jdk-8') {
            agent {
                docker {
                    registryUrl 'https://registry.hub.docker.com'
                    registryCredentialsId 'docker-hub'
                    image 'maven:3-jdk-8'
                    args '-v $HOME/.m2:/root/.m2'
                    reuseNode true
                }
            }
            steps {
                sh 'mvnw -B clean build'
            }
        }
        stage('3-jdk-11') {
            agent {
                docker {
                    registryUrl 'https://registry.hub.docker.com'
                    registryCredentialsId 'docker-hub'
                    image 'maven:3-jdk-11'
                    args '-v $HOME/.m2:/root/.m2'
                    reuseNode true
                }
            }
            steps {
                sh 'mvnw -B clean build'
            }
        }
    }
}

當我觸發該專案時，我得到了這個。

uj5u.com熱心網友回復：

Jenkins（Docker 守護程式）找不到影像。或者換句話說找不到注冊表。

  docker pull registry.hub.docker.com/maven:3-jdk-8
Error response from daemon: unauthorized: authentication required

您只需要docker.io像這樣修改配置中的注冊表 URL。

 stage('3-jdk-8') {
            agent {
                docker {
                    registryUrl 'https://docker.io'
                    registryCredentialsId 'docker-hub'
                    image 'maven:3-jdk-8'
                    args '-v $HOME/.m2:/root/.m2'
                    reuseNode true
                }
            }

或者您可以省略registryUrland，registryCredentialsId因為 maven 映像位于公共注冊表（Docker Hub）中。默認情況下，詹金斯會嘗試從那里拉出來。

 stage('3-jdk-8') {
            agent {
                docker {
                    image 'maven:3-jdk-8'
                    args '-v $HOME/.m2:/root/.m2'
                    reuseNode true
                }
            }
