land-and-deploy

To automate PR merge and production deployment, you need a workflow that merges the PR, waits for CI to pass, triggers the production release, and validates canary health to ensure safe delivery.

Canary deployment verification monitors the health of a partial production release. It validates metrics after deploying, providing an automated safety valve and rollback options if health checks fail.

Rolling back a production deployment after failed health checks requires an automated safety valve that detects issues during canary verification and triggers a revert to maintain system stability.

Triggering a production release after CI passes is possible by enforcing a deterministic sequence of steps that merges the PR, monitors the CI completion, deploys, and then validates canary health.

The best way to verify production health after a merge is to automate the deployment flow with canary verification, checking system stability and offering rollback options if health checks fail.

You should not use an automated merge and deploy workflow when your release requires manual approval gates outside of CI, or when your environment lacks canary deployment capabilities for health validation.
