Validation if kubeletconfig fields is no longer going to be supported going forward, https://github.com/openshift/machine-config-operator/issues/2357 Hence, instead of fixing it for parsing for percentage (and other things), we will just revert that PR. Hi, Harshal Patil I'd like to confirm I get your point, we just need to validate positive percentage value is acceptable by kubeletconfig. We will not support any validation in kubeletconfig (however I didn't remove the validation code that already exists). That's the reason I added a warning in CRD to let users know that validation will not be duplicated in MCO that already exists in upstream, https://github.com/openshift/machine-config-operator/pull/2358 @Harshal Patil, got you, yet I found the existing validation didn't work as expected. At least, percentage value should be allowed, for our doc introduce we can use value with % in kubeletconfig, FYI:https://docs.openshift.com/container-platform/4.6/nodes/nodes/nodes-nodes-garbage-collection.html#nodes-nodes-garbage-collection-configuring_nodes-nodes-configuring $ oc get clusterversion NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.7.0-0.nightly-2021-02-02-223803 True False 4h33m Cluster version is 4.7.0-0.nightly-2021-02-02-223803 spec: kubeletConfig: evictionPressureTransitionPeriod: 0s evictionSoft: memory.available: 20Gi nodefs.available: 6% nodefs.inodesFree: 5% evictionSoftGracePeriod: memory.available: 1h nodefs.available: 1h nodefs.inodesFree: 1h machineConfigPoolSelector: matchLabels: custom-kubelet: small-pods status: conditions: - lastTransitionTime: "2021-02-03T10:31:56Z" message: 'Error: KubeletConfiguration: invalid value specified for nodefs.available reservation in evictionSoft, 6%' status: "False" type: Failure verified on version : 4.7.0-0.nightly-2021-02-06-084550 spec: kubeletConfig: evictionHard: imagefs.available: 20Gi imagefs.inodesFree: 5% memory.available: 200Mi nodefs.available: 5% nodefs.inodesFree: 4% evictionPressureTransitionPeriod: 5s imageGCHighThresholdPercent: 80 imageGCLowThresholdPercent: 75 imageMinimumGCAge: 5m maxPods: 240 podsPerCore: 80 machineConfigPoolSelector: matchLabels: custom-kubelet: small-pods status: conditions: - lastTransitionTime: "2021-02-07T07:15:17Z" message: Success status: "True" type: Success So the previous fixes which are related with kubeletconfig field validation are deprecated, such as https://bugzilla.redhat.com/show_bug.cgi?id=1745919 and https://bugzilla.redhat.com/show_bug.cgi?id=1805019 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
