▶️ Conventional Vs Kubernetes CI/CD Pipelines

Kubernetes brings distinct paradigms that impact everything from artifact handling to deployment strategies.

📌 Many DevOps Engineers don’t fully understand how DevOps and GitOps CI/CD pipelines differ.

♾️ In a DevOps CI/CD pipeline, everything runs in one flow from code commit, tests, build, image creation, to direct deployment into the Kubernetes cluster.

It is fast and centralized but tightly couples deployment with the CI process, leaving little room for separation or control.

♾️ In GitOps pipeline, CI handles tests and builds, but deployment happens through Git commits. A controller syncs changes from the repo to the cluster.
