The Goal
Pipeline view at Persgroep Online Services
The Goal
Automate Everything
● Everything in version control○ Including infrastructure○ Build server and configuration○ Deployment scripts
We are going to...
● Automate creation of Jenkins Jobs● Automate creation of deployment package
(Docker container)● Automate deployment of Docker container● Automate creation of full Delivery Pipeline in
Jenkins
Using
● Jenkins ● Jenkins Job Builder● Docker● Bash;-)
docker run$ docker run -d -v /home/vagrant/.m2:/root/.m2
-v /var/run/docker.sock:/var/run/docker.sock -p 8080:8080 --name jenkins wouterla/docker-jenkins
● ports: -p <host-port>:<container-port>● volumes: -v <host-dir>:<container-dir>● -d: background● --name: to find it by● Image: <repository>/<name>:<tag>
https://docs.docker.com/reference/commandline/cli/
Docker stop
docker stop <name>docker stop <container-id>docker rm <name>
docker ps
Work
Start Jenkins container on port 8081
then
Stop, and switch back to 8080
Running Jenkins Job Builder
docker run wouterla/docker-jenkins-job-builder
Needs access to jenkins!
docker run --link jenkins:jenkins wouterla/docker-jenkins-job-builder
● link: <container-name>:<alias>
Our pipeline
Jenkins Job Builder
● Jobs● Projects● Job Templates● Variables
Variable types and scope
● project -> template● defaults● YAML references● macros● within and across files
Project / template
YAML references
Macros
Work
Add a new step to the pipeline that runs the maven ‘install’ goal
Docker build
● -t <repository>/<name>:<tag>● . (or -f)
But today:
$> ./build_docker_jenkins_job_builder.sh
Dockerfile
Work
Complete the Dockerfile for demo app, and build it locally
Hint: You can run the app with:java -jar jetty-runner.jar <war-file>
Dockerfile
Docker push/pull
● login● push <tag>● pull <tag>
Work
Add step to pipeline that builds the docker image for our demo app
Work
● Add ‘test’ phase to pipeline● Add step that deploys demo app on port
8081
Work
Add ‘production’ phase and environment running on port 8082
Work
Add second pipeline, building ‘workshop’ branch
Work
Add ‘smoketest’ step to test and production phase
