What is the proper way to stop and remove a docker container in Jenkins when using Docker Pipeline Plugin? -


i have jenkins pipeline builds , runs docker machine, not agent, using scripting block along docker pipeline plugin methods docker.build() , image.run(). works fine if build fails, docker container left running! have container.stop() in post{ always{} } block doesn't seem work. don't want ssh jenkins server delete container after every build , can't leave because has specific , necessary name. how stop , rm container regardless of failure of build?

my pipeline:

pipeline {     agent none     stages {         stage('checkout') {             agent             steps {                 checkout([$class: 'gitscm', branches: [[name: '*/master']], dogeneratesubmoduleconfigurations: false, extensions: [], submodulecfg: [], userremoteconfigs: [[credentialsid: '<some credentials>', url: '<a git repo>']]])             }         }         stage('spin receiver') {             agent             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 {         {             script {                  receiver_container.stop()             }         }         failure {             sendemail('foo@bar.com')         }         changed {             sendemail('foo@bar.com')         }     } }

here working solution. have define variable container outside main pipeline. can use anywhere in pipeline start or stop container. in particular, can remove container in post{ always{ } }.

def receiver_container pipeline {     agent     stages {         stage('checkout') {             agent             steps {                 checkout([$class: 'gitscm', branches: [[name: '*/master']], dogeneratesubmoduleconfigurations: false, extensions: [], submodulecfg: [], userremoteconfigs: [[credentialsid: '<some credentials>', url: '<a git repo>']]])             }         }         stage('spin receiver') {             agent             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 {         {             script {                  receiver_container.stop()             }         }         failure {             sendemail('foo@bar.com')         }         changed {             sendemail('foo@bar.com')         }     } }
