GitOps, Jenkins X & the Future of CI/CD

DevOps is the new legacy. We need to rethink CI/CD with Kubernetes and cloud-native development in mind. Enter GitOps, a new paradigm and set of best practices. Jenkins X aims to implement GitOps in practice, using Git as a source of truth and with built-in automation.

Tracy Miranda discusses GitOps, Jenkins X, and what the future of CI/CD for Kubernetes should look like. You’ll understand why traditional DevOps is not suitable in a Kubernetes and cloud-native world, explore GitOps principles and discover how they facilitate high-velocity app development, and learn how to use GitOps in practice to focus on your app development while using Kubernetes and open source cloud-native tools Jenkins X, Helm and Draft.

1. GitOps, Jenkins X & the Future of CI/CD Tracy Miranda, Director of Open Source Community | CloudBees tmiranda@cloudbees.com | @tracymiranda
2. So, DevOps… @tracymiranda
3. DevOps is the new legacy @tracymiranda
4. Cloud Native Technologies ▪On demand self-service ▪Broad network access ▪Resource pooling ▪Rapid elasticity ▪Measured service
5. DevOps Cloud GitOps Cloud Native
6. What would CI/CD look like if we had unlimited, scalable resources?
7. DORA State of DevOps Reports @tracymiranda
8. The Science of Lean Software and DevOps “software delivery is an exercise in continuous improvement, and our research shows that year over year the best keep getting better, and those who fail to improve fall further and further behind.” - Nicole Forsgren
9. Building and scaling high performance technology organisations @tracymiranda
10. GitOps @tracymiranda Operation by pull request Git as the single place where we operate All changes are observable
11. The GitOps Effect: Delivering Quality at Speed 2 150+ deployments per week Via @fractallambda ref: https://twitter.com/tracymiranda/status/1045693846464729094

14. Best Practices for CI/CD for cloud native apps 1. Figure out the best practices of how to CD cloud native apps • Not just build and test, but review, promote, changelog, collaborate, etc. 2. Integrate best of breed software in this ecosystem to achieve it 3. Kubernetes as foundation & means to an end 4. Multicloud: Democratize it by building a high level, pleasant CLI 5. GitOps: deployments should be recorded and tracked in Git

23. “Friends don’t let friends install Kubernetes” - James Strachan, Jenkins X
24. You can have fun tinkering
25. Or you can just get productive
26. MultiCloud Support jx create cluster minikube
27. MultiCloud Create Cluster Install kubectl, Helm, Jenkins X, etc • az, gcloud, kops, eksctl, oci Install cloud provider CLI • RBAC,default storage class, enable docker registries, etc Create Kubernetes cluster • Create default namespace • Setup the ingress controller • Configure git source repository • Create admin secrets Configure

34. Wrap-up
35. Wrap Up ▪ Cloud native & Kubernetes are a major industry shift ▪ GitOps has essential techniques and practices to help you go faster without costing you stability. ▪ Jenkins X focuses on best practices for CI/CD for Kubernetes ▪ CI/CD is evolving forward quickly: serverless, progressive delivery ▪ We’re all on this journey, let’s drive things forward together
