GitOps has taken the DevOps world by storm since Weaveworks introduced the concept back in 2017. The idea is simple: use Git as the single source of truth to declaratively store and manage every component for a successful application deployment. This can include infrastructure-as-code (e.g., Terraform, etc.), policy documents (e.g., Open Policy Agent, Kyverno), configuration files, and more. Changes to these components are captured by Git commits and trigger deployments via CI/CD tools to reflect the desired state in Git.
