What is GitOps?

GitOps is an approach to managing infrastructure and applications where all configuration is stored in a Git repository, and changes are automatically applied to the target environment through automated processes.

The main idea of GitOps:

• Git serves as the single source of truth for the system's state.
• Any changes go through Git (e.g., pull request), ensuring auditability and version control.
• Automated agents (operators) monitor the environment's state and synchronize it with the configuration from Git.

Example: when the configuration of Kubernetes manifests in Git is changed, the operator automatically applies these changes to the cluster.

This increases reliability, transparency, and deployment speed, as well as simplifies rollback of changes.
