08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned very positive feedback and later became a recurring show. Eventually, this work led us to the Cloud Native Computing Foundation’s GitOps Working Group (and later the OpenGitOps project). By then, GitOps and versioned in Git, and by taking advantage of declarative configurations in Kubernetes. Cloud-Native DevOps So if GitOps isn’t anything new, why are we hearing so much about it now? Much like how
