What is GitOps?

GitOps is a way of managing infrastructure and application deployments using Git as the single source of truth.

Instead of manually deploying applications or making changes to infrastructure through the cloud console or CLI, you define everything in Git repositories. Then, an automated system continuously ensures that what is running in the environment matches what is in Git.

You define the desired state (e.g., Kubernetes manifests, Terraform configurations) in a Git repository.

A GitOps tool (like ArgoCD or Flux) monitors the Git repository for changes.

When a change is detected, the tool automatically applies the new configuration to the infrastructure.

If something is manually changed outside of Git, the tool detects the drift and corrects it.

✅ Automation – No need for manual deployments.

✅ Version Control – All changes are tracked in Git.

✅ Consistency – Ensures that production matches what is defined in Git.

✅ Rollback – Easily revert to a previous version if something breaks.

🔹 ArgoCD – Used for Kubernetes deployments.

🔹 FluxCD – Another Kubernetes GitOps tool.

🔹 Terraform + GitOps – Infrastructure as Code with automation.

GitOps is gaining more focus these days in Micro Services Environments.
