Best practices to keep secrets out of GitLab repositories

This post reinforces best practices for preventing secrets from being exposed in GitLab repositories. It highlights the importance of limiting public visibility of projects, securing CI secrets using external secret managers (GCP Secret Manager, AWS KMS, HashiCorp Vault), and enabling GitLab's comprehensive secret detection capabilities: secret push protection, pipeline secret detection, and client-side secret detection. It also provides guidance on incident response for accidental credential leaks, including resetting credentials and reviewing logs.
