GitOps is more than just running an agent inside a Kubernetes cluster to pull changes from a repository. It represents a paradigm shift where your version control system becomes the single, absolute source of truth for the desired state of your entire production infrastructure.
Establish Declarative Manifests First
You cannot adopt GitOps if your infrastructure relies on manual server configurations or imperative command-line scripts. Every resource, from Kubernetes ingress rules to cloud database configurations, must be declared as code and committed to a central repository before automation can begin.
Define Your Reconciliation Loop
The heart of GitOps is the active reconciliation agent that constantly compares the actual state of your cluster with the target state defined in Git. When configuration drift occurs due to manual intervention, the agent must automatically revert those changes to prevent security vulnerabilities and configuration drift.
Secure Your Deployment Pipeline
By shifting to a pull-based deployment model, you no longer need to store sensitive administrative credentials in your external CI/CD tool. The cluster pulls updates from the repository internally, which significantly reduces the attack surface and simplifies your overall network security architecture.
