Does Jenkins Pipeline Plug-in support Docker Compo

问题:

I'm looking for a way to run Docker-enabled build consisting of multiple containers in Jenkins 2.0.

Are there any plans for native support of Docker Compose in Pipeline, or through CloudBees docker plugins for pipeline.

Or can/must this be addressed by explicit calls sh docker-compose...? Maybe even use them inside try... finally to further control services lifecycle.

EDIT: The first answer was to suggest a way to build docker containers in jenkins. This is not what is needed here. I (EngineerDollery) want to bring up my target platform in jenkins using compose so that I can deploy my app to it and run end-to-end tests.

回答1:

After searching in Jenkins bug tracking, JENKINS-35025 suggests docker-compose.yml is taken into account when running a job in a docker container, using a maven build.

See also Creating CI pipeline with Jenkins, which assumes docker-compose is installed on your Jenkins server.

Note: a year later (August 2017), docker-compose is still not supported in the Docker Pipeline plugin

July 2018, Ivan Aracki notes in the comments:

Manually installing docker-cli and docker-compose with the same version as host's is the solution for now...

Here are the files to run a jenkins container that runs docker inside:

docker run \
  -p 8080:8080 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  --name jenkins \
  getintodevops/jenkins-withdocker:lts

I am facing a similar problem, I found this https://reinout.vanrees.org/weblog/2017/10/03/docker-compose-in-jenkins.html but I do not know what is related to.

My problem is test while developing, and also automate the test in Jenkins, and I am using docker-compose to bring up some php scripts AND a mysql server, to run isolated tests (phpunit as of now).

I could think I can achieve this by

1. creating a network in docker host (with docker network create)
2. create and run a mysql docker attached to that network (with docker run mysql --network=netname --name=mysqlmachine
3. run scripts by jenkins specifying --network and refering to mysqlmachine as host.

But this would means I need to setup db data, cleanup db data, and also leave always on the mysqlmachine even when not needed, consuming some ram resource. I can solve last problem with docker start mysqlmachine and docker stop mysqlmachine command in my Jenkinsfile defining the pipeline.

But, again, executing a shell into the docker where jenkins is running I can not find docker command

For me is a viable solution untill I can not find something better

UPDATE: I will try the https://wiki.jenkins.io/display/JENKINS/Docker+Slaves+Plugin solution, it has almost what I need

UPDATE 08.02: as suggest by Alexander Zeitler, using

agent {
        docker {
            image 'pdmlab/jenkins-node-docker-agent:6.11.1'
            args '-v /var/run/docker.sock:/var/run/docker.sock'
        }
    }

in Jenkins file allow the use of docker-compose command: docker inside a docker, that is mostly docker near a docker as detailed here: Docker in Docker - volumes not working: Full of files in 1st level container, empty in 2nd tier

But I preferred to use another approach, that does not require to run jenkins in a special way.

The pipeline say:

stage('Test') {
    steps {
        sh './build_docker.sh jenkinstests'
    }
}

and build_docker.sh does:

 jenkinstests)
 docker volume create idealodbconn
 docker run -v idealodbconn:/data --name helper busybox true
 docker cp ./dbconn/db249.json helper:/data
 docker rm helper

 docker-compose -f services/docker-compose-jenkins.yml up \
 --abort-on-container-exit \
 --exit-code-from idealoifapi

 docker-compose -f services/docker-compose-jenkins.yml rm -f
 docker volume rm idealodbconn
 ;;

Also here --abort-on-container-exit say to exit once one container defined into docker-compose-jenkins.yml exits, and --exit-code-from idealoifapi says to take exit code from idealoifapi image.

That is all. Missing part, maybe, is the docker-compose-jenkins.yml use of volume, it is external: true:

volumes:
    idealodbconn:
        external: true
