Create a failover cluster. What do you advise?

Question

linux

Hello. So, my task is to deploy a LAMP stack in a fault-tolerant configuration.
If one Apache died, another replaced him. The same with a DB. In my case it is MySQL. Fault tolerance of a DB should be implemented by means of Galera. Virtual machines will be raised using Docker. It is unlikely that there are people here who are well acquainted with Kubernetes, but I will need this technology in order to manage all this. In general, closer to the essence of the issue, I do not hope that you will sort out each step of this task for me, it was not bad of course) I would like good literature from you on the basics of all this, not on specific technologies, but on the basics. Something like a cluster configuration, the basics of replication, and so on. So that in the future, using ready-made solutions, I understand what I'm doing. Thank you.

Nginx is able to balance and exclude failed services (Apache or PHP).
