Jenkins声明性管道docker:命令未找到 [英] Jenkins Declarative pipeline docker: command not found

问题描述

我已经在计算机上本地安装了Jenkins.我从我的github存储库中提取了一些源代码，该存储库的根目录中有一个Docker文件.我想构建和放置docker image并将其推送到docker hub，但是构建失败并显示以下消息...

I have installed Jenkins locally on my machine. I pulling some source code from my github repository which has a Docker file in the root directory. I want to build and docker image and push it to docker hub but my build fails with the following message...

docker build -f myapp-web:latest . \n
/Users/Shared/Jenkins/Home/workspace/MyApp@tmp/durable-ee9851e9/script.sh: line 1: docker: command not found 

pipeline {

    agent any

    tools {
        maven 'maven_3.6.1'
        jdk 'jdk8'
    }

    stages {
        stage('Build') {
            steps {
                withMaven(maven: 'maven_3.6.1', mavenSettingsConfig: '5d7a8237-6d6a-4189-a907-518900dc7755') {
                    sh "mvn clean install "
                }
            }
        }
        stage('Build Image') {
            steps {
                script {
                    sh 'docker build -f myapp-web:latest .'
                }
            }
        }
        stage('Deploy Image') {
            steps {
                withDockerRegistry([credentialsId: "docker-hub", url: ""]) {
                    sh 'docker push myapp-web:latest'
                }
            }
        }
    }
}

Docker已在我的本地计算机上安装并运行，并且使用以下插件配置了Jenkins Docker管道 Docker插件

Docker is install and running on my local machine and Jenkins is configured with the following plugin Docker pipeline Docker plugin

任何想法都值得赞赏

推荐答案

如果通过管道获取docker: command not found，尽管它已安装在运行管道的同一节点上，则需要确保管道正在读取正确的$PATH环境，其中应该存在docker二进制文件.

If you are getting docker: command not found through the pipeline although its already installed on the same node where the pipeline is running, you need to ensure that the pipeline is reading the correct $PATH environment where the docker binary should be exist.

您提到的第二个问题

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock

您需要将管道中正在使用的用户添加到docker组，以便它可以使用以下命令运行docker命令:

you need to add the user that is being used within the pipeline to the docker group so it can run docker commands using:

usermod -aG docker $USER
