Jenkins on Kubernetes

Meetup at Gurgaon Kubernetes Meetup

1. Jenkins On Kubernetes
2. We all want to be High Performing Teams !
3. Development teams need to figure out : • How to do microservices well ? • How to do Kubernetes well ? • How to do cloud well ? • How to automate CI / CD ? • A LOT OF STUFF !
4. Introducing Jenkins X
5. Jenkins X • Built on Jenkins foundations, recharges it — doesn’t replace it. • Rethinks how developers should interact with CI/CD in the cloud through automation, tooling and DevOps best practices. • Understands clouds and Kubernetes natively. You no longer need to play around with Kubernetes setup in Jenkinsfile • Build for modern cloud with modern development practices
6. How does Jenkins X help ? • Automates the setup : tools + environment ◦ Jenkins, nexus, helm, skaffold • Automates CI/CD for your applications on Kubernetes ◦ Docker Images ◦ Helm charts ◦ Pipelines
7. • Use GitOps to manage promotion between environments ◦ Test -> Staging -> Production ◦ Configuration stored in Git • Lots of Feedback ◦ E.g commenting on issue as they hit staging + Production
8. What does Jenkins X give me? • Development Tools Environment ◦ Jenkins master ◦ Elastic pool of Kubernetes build pods • Staging Environment • Production Environment • CI/CD configured out of the box
9. How can we use Jenkins X? • With existing cluster: ◦ jx boot • With a Jenkins X managed kubernetes cluster: ◦ jx create cluster gke --skip-login • You can use any Kubernetes provider such as AWS EKS, OpenShift, or your own handmade cluster.
10. Using Jenkins X for Projects • Import existing projects using ◦ jx import ◦ Creates a Dockerfile, Jenkinsfile, Helm charts and configures build packs for deployment • Create new projects with ◦ jx create quickstart
11. • This will setup a new project with Jenkins X configured. Changes will automatically go into the staging environment • Once you are happy, promote the build to production ◦ jx promote • Comment on PRs, merging will finalize the deployment! • Profit!
12. Advanced Strategies • GitOps • Canary deployments • Staged rollouts • Blue Green deployments
13. Comparing Traditional CI/CD to Jenkins X Jenkins • Holistic, makes no assumption on what's running • Familiar • Straightforward Jenkins X • Opinionated. Brings a host of baggage • Paradigm shift. Needs you to rethink what you do with your project; configure build-packs etc
