- 6. 6 ● GitOps is an app dev and operations methodology ● GitOps is a methodology, not a specific tool or technology. ● GitOps applies to everything and brings business value. What is GitOps? … and why do I want it?
- 7. 7 GitOps leverages: ● an entire system that is described declaratively ● code that is version controlled and ● software agents that reconcile and ensure correctness (along with alerts, etc). 4 Principles of GitOps

- 11. CI/CD Pipelines…. Let’s talk about them CI/CD: - unit tests - container build - container publish - update deployment configuration - deploy your app to the cluster - reconciliation of cluster? 2023
- 12. GitOps have decoupled the CI/CD pipelines CI: - unit tests - container build - container publish - update deployment configuration CD: - deploy your app to the cluster - reconciliation of cluster? yes! 2023
- 13. GitOps have decoupled the CI/CD pipelines CI (PUSH): - unit tests - container build - container publish - update deployment configuration CD (PULL): - deploy your app to the cluster - reconciliation of cluster? yes! 2023
- 14. When and where do we run our tests? - On application build - On application deployment - Compute intensive tests? - On cluster reconciliation? 2023
- 15. Because of Testing, CI is still coupled to CD - CI needs access to the cluster - CI somehow needs to know the state of the cluster - am I testing the new version of the app? - is the cluster fully reconciled? 2023
- 16. Even more questions - Re-running tests? (retrigger the entire pipeline?) - Saving tests artifacts? (Cypress videos) - Whose responsibility is this? 2023
