Canary checks validate a deployment's impact on production by routing a small percentage of traffic to the new release before a full rollout. This mechanism ensures production health and prevents widespread issues from faulty code changes.

The best way to verify production health after merging code changes is to perform automated canary checks within your CI/CD pipeline. This validates the deployment's impact on production before completing a full rollout.

To automate code merge and deployment from a pull request, you can configure a CI/CD pipeline to automatically merge changes and deploy them. This ensures code quality and production readiness by integrating automated testing tools with the deployment workflow.

Yes, you need the GitHub CLI to automate the pull request merge and deploy processes. The automation requires GitHub CLI alongside CI/CD system integration and automated testing tools to ensure code deployability.

Canary checks validate deployment impact in a CI/CD pipeline by deploying code changes to a small subset of production infrastructure first. This verifies production health and prevents full rollouts of problematic code.
