When Bhupi Sir steps into the Kubernetes cluster, even the pods start scheduling "panic" events!

[@rohitsinha1645]

Thanks!

[@umershaikh531]

so basically namespaces give you isolations and you can create pods with same name in different namespaces. resource quota is basically applied over namespaces and limit-ranges are set over pod, container, pvc and in case of resource quota you can also mention pod limit configmap limit too.

[@varunindrajeetanand95]

It is great experience while Learning DevOps by Bhupinder sir ... He remove my thinking about DevOps as a hard one only for Experienced one . He made me believe that it's also capable for fresher / non tech . Thanks a lot sir from the bottom of heart.
