This article delves into getting started running pods with controllers in Kubernetes.

Running pods with controllers

Pods are too simple to be useful on their own — they’re isolated instances of an application, and each pod is allocated to one node. If that node goes offline then the pod is lost and Kubernetes doesn’t replace it. You could try to get high availability by running several pods, but there’s no guarantee Kubernetes won’t run them all on the same node. Even if you get pods spread across several nodes, you need to manage them yourself — and why do that when you’ve an orchestrator which can manage them for you?
