jenkins - 在多个阶段之间重用 Jenkins 中的代理(docker 容器)

Question

我有一个具有多个阶段的管道，我想在“n”个阶段之间重用一个 docker 容器，而不是所有阶段:

pipeline {
   agent none

   stages {
       stage('Install deps') {
            agent {
                docker { image 'node:10-alpine' }
            }

            steps {
                sh 'npm install'
            }
        }

       stage('Build, test, lint, etc') {
            agent {
                docker { image 'node:10-alpine' }
            }

            parallel {
                stage('Build') {
                    agent {
                        docker { image 'node:10-alpine' }
                    }

                    // This fails because it runs in a new container, and the node_modules created during the first installation are gone at this point
                    // How do I reuse the same container created in the install dep step?
                    steps {
                        sh 'npm run build'
                    }
                }

                stage('Test') {
                    agent {
                        docker { image 'node:10-alpine' }
                    }

                    steps {
                        sh 'npm run test'
                    }
                }
            }
        }


        // Later on, there is a deployment stage which MUST deploy using a specific node,
        // which is why "agent: none" is used in the first place

   }
}

您可以使用 scripted pipelines ，您可以在其中放置多个 stage走进 docker步骤，例如

node {
  checkout scm
  docker.image('node:10-alpine').inside {
    stage('Build') {
       sh 'npm run build'
     }
     stage('Test') {
       sh 'npm run test'
     }
  }
}
