GitOps Adoption Readiness Checklist
A readiness checklist for adopting GitOps that gates on fully declarative state, a chosen controller and repo topology, Git-safe secrets, tested revert-based rollback, and drift-correcting reconciliation.
When to Use This Checklist
Use this before adopting GitOps, the practice of driving infrastructure and application delivery from declarative state stored in Git and reconciled by a controller such as Argo CD or Flux. GitOps brings auditability, easy rollback, and drift correction, but only if the prerequisites are met. This checklist confirms readiness before you flip the switch.
It fits teams running Kubernetes who want to move from imperative deployment scripts to declarative, Git-driven delivery.
How to Use This Checklist
The foundational requirement is declarative state: if any part of your environment is configured by hand or imperative scripts, GitOps cannot manage it. Get everything into manifests, Helm, or Kustomize first. Then choose a controller and repository topology, and define how changes promote from dev to staging to production through Git.
Secrets are the classic GitOps stumbling block, so settle on a Git-safe secrets strategy early. Enable drift detection and self-healing, prove rollback via Git revert, and pilot one application before rolling GitOps out widely.
What Good Looks Like
A GitOps-ready team expresses all desired state declaratively, with config repos separate from source and protected by branch reviews. A controller reconciles state continuously, detects drift, and self-heals. Promotion flows through Git, secrets are handled with a Git-safe mechanism, and rollback by Git revert has been tested. RBAC governs who can change which environment, and a pilot application has proven the workflow before broad adoption.
Common Pitfalls
The foundational pitfall is adopting GitOps while still applying changes imperatively on the side, which causes constant drift and undermines the model. Putting plaintext secrets in Git is a serious security failure; a Git-safe strategy is mandatory. Skipping branch protection lets unreviewed changes reach production. Disabling self-healing forfeits a core GitOps benefit. And rolling out to every team before a pilot multiplies early mistakes.
