What is GitOps?

GitOps is an operations model where the desired state of servers, Kubernetes resources, and application configuration is stored in a Git repository, then continuously reconciled with the live environment. The goal is to reduce manual production changes and make every change auditable.

When a team wants to release a new service version, it updates a manifest and opens a pull request instead of running commands directly against the cluster. After approval and merge, a tool such as Argo CD or Flux synchronizes the cluster with the Git state.

How Does It Work?

In a GitOps workflow, the Git repository is treated as the source of truth. CI builds and tests the artifact; the deployment controller applies manifests, Helm charts, or Kustomize output to the target environment. If the live environment drifts from Git, the controller can report or revert the difference.

Access control is a major part of the model. Instead of granting broad production access to individuals, changes flow through Git history, pull request review, and audit logs.

Business Use

GitOps is useful for Kubernetes platforms, multi-environment deployments, and regulated systems where teams need a clear answer to who changed what and when. It supports staging-production separation, rollback, and disaster recovery because the environment can be reconstructed from versioned configuration.

GitOps does not replace CI/CD by itself; it provides the controlled deployment side of the pipeline. For very small projects it can add process overhead, but with multiple teams and environments it creates a much clearer operations model.
