From Jenkins Freestyle jobs to Pipeline, with JobDSL. Seed jobs¶
- Meetup event: From Freestyle jobs to Pipeline, with JobDSL
- Manually managing Jenkins jobs is painful. Jenkins Pipeline exists, but how do you get started and why should you bother in the first place? Journey with Nicolaj, as he talks about the pains of managing a manually configured job in Jenkins; converts a Freestyle Job to JobDSL, instantly; introduces mechanisms for adding the jobs to Jenkins, as code; and ultimately converts the job to a Jenkins Pipeline!
- Just like last time, in the talk “Configuration as Code of Jenkins (for Kubernetes),” you’ll see plenty of live demos and get to take home all the code and examples afterwards. Use it as the starting point for taking advantage of the Configuration as Code (CasC) that everyone is talking about, and hopefully it will save you a lot of headache in the future!
- Agenda:
- Manual Freestyle jobs, and why they hurt us
- Introduction to JobDSL and adding JobDSL-jobs to Jenkins
- From Freestyle Jobs to JobDSL, the beginning of our CasC adventure
- From JobDSL to Pipeline, all the fun of CasC; with even more resilience!
- Nicolaj Græsholt is a Continuous Delivery and DevOps Consultant and Trainer from Eficode Praqma. He helps organizations with all things CI/CD, Artifact Management, Git, Docker and Kubernetes, and he’s a Certified Kubernetes Administrator of CNCF.

Jenkins Scripts¶
- cleanup.Jenkinsfile: Jenkinsfile with Declarative Pipeline Multiline sh that cleanups old builds. All the Stages are now visually monitored. It is triggered every saturday night and ends with jenkins restart. These Multi-line bash commands make easier to read Jenkins Projects.
- daily_restart.Jenkinsfile: A script that automatically triggers a daily restart of Jenkins due to performance issues (Jenkins is a Java application). Jenkins with Declarative Pipeline multiline sh that restarts Jenkins every night except on Saturday nights (when cleanup.Jenkinsfile is triggered).
- confluence6-docker-build.Jenkinsfile: Declarative Jenkinsfile for building and uploading a docker image to Openshift-DEV, Dockerhub and Openshift-PROD (Stages are disabled via Conditional Build Steps). Tip: A Docker Plugin for Jenkins can easily replace this Jenkinsfile.
