Slides from my workshop "Continuous Delivery with Docker and Jenkins Job Builder" as given at the XP2015 conference. See http://www.lagerweij.com/2015/06/01/xp2015-workshop-continuous-delivery-using-docker-and-jenkins-job-builder-2 for more details.

1. Continuous Delivery
with
Docker &
Jenkins Job Builder
Wouter Lagerweij
@wouterla

2. Prepare!
See the Readme.html in the main directory:
● copy contents of usb stick to harddrive
● open workshop-docker-jenkins dir
● type ‘vagrant up’
● type ‘vagrant ssh’
● type ‘docker ps’

4. The Goal
Pipeline view at Persgroep Online Services

5. The Goal

6. Automate Everything
● Everything in version control
○ Including infrastructure
○ Build server and configuration
○ Deployment scripts

7. 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

8. Using
● Jenkins
● Jenkins Job Builder
● Docker
● Bash;-)

9. 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/

10. Docker stop
docker stop <name>
docker stop <container-id>
docker rm <name>
docker ps

11. Work
Start Jenkins container on port 8081
then
Stop, and switch back to 8080

12. 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>

13. Our pipeline

14. Jenkins Job Builder
● Jobs
● Projects
● Job Templates
● Variables

19. Variable types and scope
● project -> template
● defaults
● YAML references
● macros
● within and across files

20. Project / template

21. YAML references

22. Macros

23. Work
Add a new step to the pipeline that runs the
maven ‘install’ goal

24. Docker build
● -t <repository>/<name>:<tag>
● . (or -f)
But today:
$> ./build_docker_jenkins_job_builder.sh

25. Dockerfile

27. 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>

28. Dockerfile

29. Docker push/pull
● login
● push <tag>
● pull <tag>

30. Work
Add step to pipeline that builds the docker
image for our demo app

32. Work
● Add ‘test’ phase to pipeline
● Add step that deploys demo app on port
8081

34. Work
Add ‘production’ phase and environment
running on port 8082

35. Work
Add second pipeline, building ‘workshop’
branch

36. Work
Add ‘smoketest’ step to test and production
phase
