Question

在 Jenkinsfile 中，我尝试下载 docker 镜像并在此 docker 镜像中使用所有 git pull 和前端构建内容。

我的 jenkinsfile 到此为止：

pipeline {
    agent any

    stages {   
       stage('Install Docker-CE') {
            steps {
                sh '''curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
                sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
                sudo apt-get update
                sudo apt-get install -y docker-ce'''
            }
        }
        stage('Start Docker') {
            steps {
                sh 'sudo service docker start'
                sh 'sudo service docker status'
            }
        }
        stage('Verify Docker') {
            steps {
                sh 'sudo docker run hello-world'
            }
        }

        stage('Build Back End') {
              steps {
                  git ([url : 'https://github....git', branch : 'develop', credentialsId : 'xxx' ]) 
              }
        }
}

docker 已安装并正在运行，因为在我运行 sudo service docker status 的“启动 Docker”步骤中，它显示：Docker 正在运行

但是在下一步中尝试执行“hello world”时，它显示 docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

我还尝试使用以下命令运行 docker 守护进程：sudo dockerd 但它没有帮助，这是输出的一部分：

好的，问题是我在 sudo 中使用了 sudo docker run hello-world。没有 sudo 它可以工作...

在 Jenkins 管道中使用 docker 失败
