Blue-green deployment switches traffic between two identical production environments instantly, while canary deployment routes a small percentage of traffic to the new version incrementally. This Skill explains both strategies to help minimize downtime and risk.

You can create a multi-stage Dockerfile by separating the build environment from the final runtime image to reduce size. This Skill provides ready-to-use multi-stage Dockerfile examples for Node.js, Go, and Python web applications.

Essential CI/CD pipeline stages include building the application, running tests, building Docker images, and deploying. This Skill provides a GitHub Actions configuration example and outlines necessary pipeline stages for reliable web application delivery.

Implement health checks by exposing dedicated endpoints for liveness and readiness probes in Kubernetes. This Skill details how to configure health check endpoints and Kubernetes probes to ensure your web application is production ready.

The best way to configure environment variables is storing config in the environment rather than in code, following the Twelve-Factor App methodology. This Skill demonstrates environment configuration validation for robust web application deployment.

You can roll back a failed deployment by switching traffic back to the previous stable version instantly. This Skill covers instant rollback strategies and provides a production readiness checklist to help prevent deployment failures.
