    GitOps replaces manual cluster changes with audited, version-controlled delivery. The result is less drift, clearer ownership, and faster recovery when something goes wrong.

    Why GitOps works in real teams

    Most delivery pain comes from hidden state. GitOps makes the repository the source of truth, so promotions, rollbacks, and audits become predictable.

    Reference architecture

    A common setup uses a shared infrastructure repo for cluster-wide tooling and an application repo per service. FluxCD watches these repositories and reconciles the desired state automatically.

    Bootstrap flow

    Start by bootstrapping FluxCD into the cluster, then apply separation between platform and application configs. Keep secrets in a dedicated workflow so deployment configs stay readable.

    Example bootstrap command: `flux bootstrap github --owner=org --repository=platform --path=clusters/prod`

    Promotion and rollback

    Use versioned manifests and immutable tags to promote safely. Rollbacks are a git revert with a clear history instead of a scramble of manual changes.

    Operational guardrails

    Add policy checks, drift detection, and alerting so you catch failures quickly. GitOps gives you the control plane; observability closes the loop.
