Description Jason Montleon 2020-06-20 18:16:48 UTC 
Description of problem:
Update migration-controller limits to value higher than 800Mi

Customer reported needing at least 6Gi to stop the controller from being OOM Killed once they started using at scale

Version-Release number of selected component (if applicable):
1.2.2

How reproducible:
Always in a large enough environment

Steps to Reproduce:
1. Deploy CAM
2. Creat a couple hundred plans
3.

Actual results:
Controller is OOM killed

Expected results:
controller is not OOM killed

This possibly applies to the CPU limit as well.

Verified by running testcase OCP-34828 - Default controller limits value:


Those are the new controller limits by default.


DISCOVERY

 oc get deployment migration-controller -o "jsonpath={.spec.template.spec.containers[?(@.name=='discovery')].resources.limits}"

map[cpu:1 memory:10Gi]

CAM

oc get deployment migration-controller -o "jsonpath={.spec.template.spec.containers[?(@.name=='cam')].resources.limits}"


map[cpu:1 memory:10Gi]
