'classic Apache/MySQL/PHP stack: you might be tempted to run all the components in a single container. However, the best practice is to use two or three different containers: one for Apache, one for MySQL, and potentially one for PHP if you are running PHP-FPM.'

I have a vague memory of a lesson where we talked about using a single container, but it seems like that could lead to issues with availability.

I feel like we practiced a question similar to this, and I think packaging each component separately was emphasized as a best practice.

I'm not entirely sure, but I think using readiness and liveness probes is crucial for ensuring the application is healthy in Kubernetes.
