Deployment Protection Rules
ELI5 — The Vibe Check
Deployment Protection Rules are the bouncers at your production club. They check IDs (approvals), enforce wait times, and even call external systems to verify everything's good before letting a deploy through. No sneaking into production on a Friday at 5 PM.
Real Talk
Deployment protection rules in GitHub Environments enforce gates before deployments proceed. Built-in rules include required reviewers and wait timers. Custom protection rules via GitHub Apps can integrate external checks like change management systems, security scans, or compliance validators.
When You'll Hear This
"Our protection rules require a lead engineer to approve production deploys." / "We added a 15-minute wait timer to catch last-minute rollback decisions."
