Chen Yu Teng commented on YUNIKORN-706:
---------------------------------------

I also check this part how to calculate resource in kubernetes.
Its logic is similar to related doc.

Following link will make it read easily:

> Init-container resources currently got skipped:
> Steps to reproduce:
>  # Submit pod with init containers.
>  # Check UI for app allocations. It only displays the container request of 50m/50M, and not the initContainer request of 100m/100M.
> {code:java}
> 9650-mbp15-rozhang:~ rozhang$ kubectl get pods -n dev
> NAME    READY   STATUS     RESTARTS   AGE
> app-4   0/1     Init:0/1   0          5s
> {code}
> From describe node, we see requests of 100m/100M, which is not the same as Yunikorn.
