Kubernetes is a scheduler for Docker containers. So lets say you want the following:
1 x MySQL Master
2 x MySQL Slave
5 x PHP Server
1 x Monitoring Script
Each of those would be a docker container. Kubernetes would figure out which host to place them on and verify that they are running, rebooting them on another host if one of your hosts goes down.
