stbenjam Deploy Service
Promotes a build from staging to production behind the payments feature flag. The rollout is gradual: 5% of traffic, then 50%, then everything.
Steps
- Confirm the staging smoke tests are green — see the smoke test guide.
- Promote the build with
payctl promote --canary. - Watch the error-rate dashboard for ten minutes.
- Roll forward, or follow the rollback runbook.
Escalate to the on-call engineer named in the rota when the error rate crosses 0.5%.
