To achieve zero downtime deployment using a CI/CD pipeline, you can implement strategies like Blue-Green or Canary deployments. This approach utilizes automated testing and building via GitHub Actions to update your application seamlessly without interrupting user traffic.

The best way to optimize a Dockerfile for production readiness is using multi-stage builds. This technique minimizes the final image size by separating the build environment from the runtime environment, resulting in faster deployments and a smaller attack surface.

Kubernetes health checks work by using probes to monitor your application's availability. Implementing robust health check endpoints allows Kubernetes to automatically restart failed containers or route traffic only to healthy instances, ensuring reliable software delivery.

Use canary deployments when you need to release a new version to a small subset of users to monitor for issues before a full rollout. Choose rolling deployments for gradually replacing old instances with new ones across your infrastructure to maintain steady availability.

Yes, adhering to Twelve-Factor App principles for environment configuration is essential in Docker deployments. This methodology separates config from code, ensuring your web applications remain portable and scalable across different deployment environments.
