Re: quota question



It's definitely not the latter (requested memory for the node is 15GB total).  It would almost certainly place B, then if A doesn't release memory it would be evicted because it is using the most over its request on the node and there is no other priority rules in place (guaranteed -> burstable -> best-effort)

Want to validate a statement.

 

Just assume, we have a only one node with 60 GB memory. Pod A scheduled with request of 10 GB and no limit. After some time, it start using 55 GB ( ignore systems reserves for now). system now has only left with 5 GB free. If new podB scheduled with request of 10GB, what is systems behavior?

 

  • Will it place Pod A and evict PodB softly since it can’t accommodate both pods on same node?
  • Scheduling fail to pod B since it can’t accommodate since node doesn’t enough requested memory?
