The document discusses the integration of Jenkins with OpenShift for Continuous Integration/Continuous Deployment (CI/CD) workflows. It highlights the benefits of using containers and OpenShift features, such as application blueprints and source-to-image (s2i) capabilities, to streamline the CI/CD process. The presentation also includes a demo and emphasizes the importance of creating a customized, easy-to-manage CI/CD pipeline.
CI/CD with Openshift and Jenkins
- 1. CI/CD with OpenShift and Jenkins by Ari LiVigni, Michal Fojtik, and Aaron Weitekamp
- 2. Agenda ● Introduction and Goals ● Jenkins Master/Slave Setup and Tools ● CI/CD Workflow and Pipeline ● Demo ● Q&A
- 3. Why Containers? ● Speed ● Agility (Cattle vs Pets) ● Microservices are real ● Ephemeral nature enforces persistent data volume ● Portability / reproducibility
- 4. Why OpenShift? ● Run containers in cluster, DNS routing ● Application blueprints (templatize microservices) ● Integrated components and services: Builds, Docker Registry, Jenkins and more... ● Source-to-Image (S2I)
- 5. ● Generalize a container-based CI/CD pipeline 1. Test every code change automatically 2. Build image and promote manually 3. Deploy to Stage 4. Deploy to Production ● Prevent promotion of broken builds Goals
- 6. Jenkins on OpenShift ● Master / Slave ● S2I allows customization of Jenkins image ● Template to turn any builder image into a Jenkins slave ○ Slaves reach out to Jenkins and download JNLP Java agent ○ Slave provides same environment as application runtime ○ Slaves run as Pods and are started on-demand
- 7. Jenkins Job Builder ● Jenkins jobs defined locally as YAML templates, uploaded as XML to any Jenkins Master ● Templating reduces redundancy in Jenkins jobs ● Maintain YAML, not XML ● Promotes source control management
- 9. Enough talk Show me the demo!
- 10. Conclusion ● Creating a custom CI/CD pipeline should be easy ● Openshift Roadmap, release v3.3 ○ Example https://github.com/arilivigni/openshift-ci-pipeline ○ Openshift Jenkins Plugin ● Add Delivery Pipeline plugin to show visualization ● Add more features to JJB for Promoted Build plugin
