land-and-deploy

Automating PR merge and production deployment involves merging a branch after CI passes, deploying to production, and validating health via canary checks. This workflow handles pre-merge checks, waits for CI, deploys, and rolls back on failure.

Verifying production health after deploying a merged PR is best done using canary checks. The workflow validates health after deploying to production and automatically reverts the deployment if any health verification checks fail.

Yes, you need GitHub CLI authentication to automate merging and deploying branches. The workflow requires Git and GitHub CLI access to handle pre-merge checks, merge the branch, and interact with the repository's CI and deployment tooling.

Yes, you can run a dry-run deployment before merging to production. The workflow provides a dry-run experience for first-time runs, allowing you to validate the end-to-end PR merge, deployment, and health verification process safely.

Automatic rollback when a production deployment fails works by gating merges on CI status and validating health via canary checks. If the canary checks detect a failure after deployment, the workflow automatically reverts the deployment to ensure production stability.

Using an automated workflow for merging and deploying small features reduces manual toil and error-prone handoffs. It enables fast rollouts with canary-based production risk reduction, ensuring verified health checks before assuming production traffic.
