Containerize an Apache/MySQL/PHP stack for GKE following Google best practices for availability. What should you do?

Packaging each component (Apache, MySQL, PHP) in a separate container aligns with the microservices principle and Google's best practices for GKE. This allows independent scaling, updates, and fault isolation for each service, enhancing availability. Implementing readiness and liveness probes ensures that Kubernetes can accurately determine when a container is ready to receive traffic and when it needs to be restarted, respectively. This is crucial for maintaining application health and availability. Packaging the application in a single container (monolithic approach) reduces flexibility, makes scaling individual components difficult, and increases the blast radius of failures. Using a script to orchestrate component launch or a bash script as an entrypoint for background jobs within a single container are anti-patterns in a containerized environment, as they complicate resource management, logging, and health checks, undermining the benefits of containerization and GKE's orchestration capabilities.
