Using Anthos Config Management with a GitHub repository is the best approach to automatically apply policy parameters to GKE clusters. Anthos Config Management provides a way to manage Kubernetes applications and configurations using a GitOps methodology. By integrating with a GitHub repository, you can store your configurations as code, allowing for version control, automated deployment, and policy enforcement across multiple GKE clusters.

When you commit changes to the GitHub repository, Anthos Config Management monitors the repository for updates and automatically applies those changes to the GKE clusters. This ensures that the configuration in your clusters is always in sync with what is specified in your Git repository. This capability allows organizations to manage infrastructure as code, providing better visibility, reproducibility, and compliance with organizational policies.

Other options may involve various integration mechanisms, but they do not provide the same level of streamlined and consistent policy application mechanism that Anthos Config Management offers when paired with GitHub.
