In previous posts on Kubernetes (k8s), I discussed some fundamental concepts here and also looked at the first steps here. First of all let’s understand what replicasets are and why it’s needed.

You may want a resource monitoring pod to run in each node. There’s no reason to run two pods of that type in a single node.

There also can be usecases where you want one pod to only run on certain nodes, instead of all nodes.
