land-and-deploy

You can automatically merge a PR after CI passes by using a land-and-deploy workflow that enforces gated readiness, waits for CI success, and then merges the pull request without manual intervention.

Canary-based deployment verification is a process that checks production health by monitoring a canary deployment after merging a PR, ensuring stability before finalizing the rollout or triggering a rollback.

To rollback a production deployment after merging, you can use a workflow that provides post-merge guidance and rollback options, automatically reverting changes if canary health checks detect issues in production.

Yes, a merge and deploy workflow supports gated readiness by waiting for CI to pass and verifying canary health before final production rollout, ensuring deployments only proceed when checks succeed.

You need canary checks in a CI and deploy pipeline when you must validate production health after merging a PR, ensuring that new changes do not cause failures before completing the full deployment.
