使用Docker Pipeline插件时,在Jenkins中停止和删除docker容器的正确方法是什么？

Question

我有一个Jenkins管道,它构建和运行Docker机器,而不是作为代理,但使用脚本块以及Docker Pipeline Plugin方法docker.build()和Image.run().这工作正常,但如果构建失败,docker容器将继续运行!我目前Container.stop()在一个post{ always{} }街区,但它似乎没有工作.我不希望ssh进入我的Jenkins服务器以在每次构建后删除容器,我不能保留它,因为它具有特定和必要的名称.无论构建失败,我如何停止和移动容器？

我的管道:

pipeline {
    agent none
    stages {
        stage('Checkout') {
            agent any
            steps {
                checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '<some credentials>', url: '<a git repo>']]])
            }
        }
        stage('Spin Up Receiver') {
            agent any
            steps {
                script { 
                    def receiver = docker.build("receiver",  "--rm centos7_receiver")
                    def receiver_container = receiver.run("-d -v ${PWD}/realtime_files/station_name/201707/f/20170710_191:/DSK1/SSN/LOG0_f/17001 --network='rsync_test' --name='test_receiver'")
                }
            }
        }
        stage('Run Tests') {
            agent { dockerfile { args '-v /etc/passwd:/etc/passwd --network="rsync_test"' } }
            steps {
                sh "python ./rsyncUnitTests.py"
            }
        }
    }
    post {
        always {
            script { 
                receiver_container.stop()
            }
        }
        failure {
            sendEmail('foo@bar.com')
        }
        changed {
            sendEmail('foo@bar.com')
        }
    }
}

这是一个有效的解决方案。您只需为主管道外的容器定义一个变量。然后你可以在管道的任何地方使用它来启动或停止容器。特别是，您可以在post{ always{ } }.

def receiver_container
pipeline {
    agent any
    stages {
        stage('Checkout') {
            agent any
            steps {
                checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '<some credentials>', url: '<a git repo>']]])
            }
        }
        stage('Spin Up Receiver') {
            agent any
            steps {
                script { 
                    def receiver = docker.build("receiver",  "--rm receiver_docker")
                    receiver_container = receiver.run("-d -u 0:0 -v /var/lib/jenkins/workspace/RsyncRealtime/jenkins_rt:/DSK1/SSN/LOG5_F/17191 --network='rsync_test' --name='test_receiver'")
                }
            }
        }
        stage('Run Unit Tests') {
            agent { 
                dockerfile { 
                    args '-u 0:0 -v /etc/passwd:/etc/passwd --network="rsync_test"'
                } 
            }
            steps {
                sh "sshpass -p 'test' ssh anonymous@test_receiver ls -l /DSK1/SSN/LOG5_F/17191"
                sh "python ./rsyncUnitTests.py"
            }
        }
    }
    post {
        always {
            script { 
                receiver_container.stop()
            }
        }
        failure {
            sendEmail('foo@bar.com')
        }
        changed {
            sendEmail('foo@bar.com')
        }
    }
}
