Full Explanation
Environments associate deployment jobs with protection rules and dedicated secrets/variables. Required reviewers and wait timers create human or temporal control before production secrets are exposed to the job. Deployment branch policies further limit which refs may deploy. Environments do not auto-merge Docker-related PRs, disable audit logging, or flip repository visibility. Administrators should define separate environments per stage (dev/stage/prod), minimize who can approve production, and ensure break-glass procedures are audited. Combining environments with OIDC cloud roles yields strong deployment governance without long-lived cloud keys in GitHub secrets.
