land-and-deploy

Automating PR merge, CI monitoring, and production deployment is handled by merging the PR, waiting for CI, deploying to production, and validating live health. This end-to-end release flow ensures safe merges and verifies production health through canary checks.

Canary deployment verification validates production health by running checks after deployment. If issues arise during these canary checks, automatic rollback options are triggered to revert the release and maintain system stability.

Handling CI failures during a pull request merge involves detecting the failures and applying safe merge handling. The process waits for CI to finish and prevents unsafe merges if checks do not pass.

Triggering production deployment after a PR merge is supported by taking over deployment responsibility. It waits for CI to finish, deploys to production, and validates live health signals with rollback options.

Limitations of automating production verification with canary checks include relying on accurate health signals. If canary checks detect issues, automatic rollback is required, meaning the system depends on valid health metrics to prevent bad deployments.

Land-and-deploy works with GitHub CLI to automate the PR merge process. It assumes deployment responsibility after the merge, monitoring CI and verifying production health through canary checks.
