I first built an always-on k3s lab, then discovered that a successful rollback could leave its saved YAML behind. After designing a safer GitOps path, I implemented it and tested three real behaviors: drift correction, a correctly deployed bad release, and durable recovery through a Git revert.
My Kubernetes rollback restored Version 2, but it did not update the YAML that still declared Version 3. I corrected the file manually, then designed a delivery process in which Git recorded the chosen version and the cluster followed it automatically.
I wanted a persistent Kubernetes environment without an always-on managed-cluster bill or compromising the Docker workloads already running on my Debian home server. I chose k3s, defined explicit resource boundaries, disabled components that conflicted with the host, and validated the design through deployment, networking, rollout, rollback, and desired-state checks.
