jenkins pipline 多行shell命令

在Jenkins Pipeline中，可以使用多行字符串语法来编写多行Shell命令。下面是一个示例：

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                sh '''
                    echo "Building..."
                    mvn clean install
                '''
            }
        }
    }
}

在上面的示例中，我们使用三个单引号来定义一个多行字符串，然后在步骤中使用sh命令来执行该字符串中的Shell命令。注意，每个命令都必须单独一行，并且命令与命令之间需要使用换行符分隔。

我明白了，你想问的是关于 Jenkins Pipeline 是什么吗？

Jenkins Pipeline 是一种基于 Groovy 的持续交付（CD）流水线工具，可以将软件交付流程建模为代码，从测试到部署，将整个过程自动化。

它与传统的基于界面的工具相比，具有更高的可重用性和可扩展性，可以轻松适应不同的环境和需求。同时，Jenkins Pipeline 还提供了良好的日志记录和错误处理机制，方便用户进行故障排查和调试。

jenkins pipline docker

Jenkins Pipeline is a tool that allows you to define and automate your CI/CD workflows as code. Docker is a platform that allows you to build, run, and manage containerized applications.

When using Jenkins Pipeline with Docker, you can define your build, test, and deployment steps within the pipeline code and use Docker containers to execute those steps. This allows for greater portability and consistency across different environments.

To use Docker within a Jenkins Pipeline, you will need to have the Docker plugin installed on your Jenkins instance. You can then define your pipeline stages to include steps such as building a Docker image, running tests within a Docker container, and deploying your application to a Docker registry.

Here is an example pipeline code that uses Docker:

pipeline {
  agent {
    docker {
      image 'node:12-alpine'
    }
  }
  stages {
    stage('Build') {
      steps {
        sh 'npm install'
        sh 'npm run build'
      }
    }
    stage('Test') {
      steps {
        sh 'npm run test'
      }
    }
    stage('Deploy') {
      steps {
        withCredentials([usernamePassword(credentialsId: 'dockerhub', usernameVariable: 'DOCKER_USERNAME', passwordVariable: 'DOCKER_PASSWORD')]) {
          sh 'docker login -u $DOCKER_USERNAME -p $DOCKER_PASSWORD'
        }
        sh 'docker build -t myapp:latest .'
        sh 'docker push myapp:latest'
      }
    }
  }
}

This pipeline uses the `node:12-alpine` Docker image as the build agent, installs dependencies, runs tests, and finally deploys the application to a Docker registry using credentials stored in Jenkins.
