You can install all of those servers in different containers, and then combine them in the same pod. For all intents and purposes from the outside, it will be a singular VM. But from the inside, you will be able to separate all those servers/tasks to separate containers, running from inside the same virtual localhost machine. They can also use the same PVC, making running a stateful app much more easier. You dont even need to make it a stateful set.
You get a lot of benefits with this - you will be able to easily manage each different server in the containers inside the pod. Easily manage their resource constraints. Security. You can make the pod's containers not accept connection from anything that does not belong to the particular app that they belong to. K8 will manage resources in the cluster, its autoscaling up and down, everything. All of the stuff that you had to maintain scripts or ansible to make happen in non k8 setups will be automated.
K8 is basically abstraction of the non-business stuff a lot of infra approaches were doing. Its containers inside VMs without you needing to manage VMs.
