Wei Huang reopened YUNIKORN-2009:
---------------------------------
> Placeholder pods should be created with limits
> ----------------------------------------------
>
> Key: YUNIKORN-2009
> URL: https://issues.apache.org/jira/browse/YUNIKORN-2009
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: shim - kubernetes
> Reporter: Wei Huang
> Assignee: Wei Huang
> Priority: Major
>
> In some k8s env, namespace is enabled with {*}{{LimitRange}}{*}:
> {code:java}
> apiVersion: v1
> kind: LimitRange
> metadata:
> name: default
> spec:
> limits:
> - default:
> cpu: 100m
> ephemeral-storage: 10Gi
> memory: 128Mi
> defaultRequest:
> cpu: 100m
> ephemeral-storage: 1Gi
> memory: 128Mi
> type: Container{code}
> However, shim code spawns placeholder pods with requests only, which cause
> the placeholder pods rejected by API server, and hence the whole Job gets
> into pending:
> {code:java}
> 2023-09-29T13:19:17.851-0700 ERROR cache/placeholder_manager.go:99
> failed to create placeholder pod {"error": "Pod
> \"tg-foo-task-group-foo-gang-0\" is invalid:
> spec.containers[0].resources.requests: Invalid value: \"1\": must be less
> than or equal to cpu limit"}{code}
> I'd propose setting the same amount of request to the placeholder Pod's
> limits, so system's LimitRange won't auto-set lower limits value.
