Requested memory for deployment manifest is not high enough for large clusters #34

Closed cheeseandcereal closed 5 years ago

cheeseandcereal commented 5 years ago

When running this deployment with the given manifest (https://github.com/lwolf/kube-cleanup-operator/blob/master/deploy/deployment.yaml) on larger clusters, this runs out of memory:

State:          Waiting
      Reason:       CrashLoopBackOff
    Last State:     Terminated
      Reason:       OOMKilled
      Exit Code:    137

My cluster that this failed on had ~3500 pods.

Bumping up to 100Mi seemed to work for me.

I'd recommend either changing the manifest, or leaving a comment by the resources that mentions the memory limit should be bumped up on larger clusters.
