Any inputs?

Requirement is, In a cluster with 10 CPU cores, i need to allocate 6 cores to application A (multiple pods) and 4 cores to application B (Multiple pods). Any pods labelled as appA should use CPU from 6 core pool and appB from 4 core pool.

Sorry, there wasn’t any clear question before.

Requirement is, In a cluster with 10 CPU cores, i need to allocate 6

(Multiple pods). Any pods labelled as appA should use CPU from 6 core
pool and appB from 4 core pool.

Yes, see the docs for node selectors.

Nodeselector wont be helpful i think
nodeA - total CPU core - 5
nodeB - total CPU core - 5

Requirement is,
appA pods should only use 6 cores
appB pods should use only 4 cores

Use quota and 2 different namespaces?

6

Quota needs, requests and limits to be set for each pod. So the pod can not utilize the full pool capacity.

7

Use a LimitRanger in the namespaces to assign default values? Or require your users to set pod limits? Especially for mory, you want that anyway.
