Description of problem:
I install a 4.8 ocp on OpenStack using hive, when I create a machinepool and set autoscaling minReplicas=0, admission hook allows this operation, but the remote machineset can't be created.
the machinepool has this status:
spec:
autoscaling:
maxReplicas: 12
minReplicas: 0
clusterDeploymentRef:
name: lwanhiveosp
name: infra
platform:
openstack:
flavor: m1.xlarge
status:
conditions:
- lastProbeTime: "2021-05-13T07:41:29Z"
lastTransitionTime: "2021-05-13T07:41:29Z"
message: When auto-scaling, the MachinePool must have at least one replica for
each MachineSet. The minReplicas must be at least 1
reason: MinReplicasTooSmall
status: "True"
type: NotEnoughReplicas
I checked labels in CLusterDeployment .metadata field, the version is 4.8, greater than 4.7.0
$ oc get cd lwanhiveosp -o json | jq -r ".metadata.labels"
{
"hive.openshift.io/cluster-platform": "openstack",
"hive.openshift.io/cluster-region": "unknown",
"hive.openshift.io/hiveutil-created": "true",
"hive.openshift.io/version-major": "4",
"hive.openshift.io/version-major-minor": "4.8",
"hive.openshift.io/version-major-minor-patch": "4.8.0"
}
In this part https://github.com/openshift/hive/blob/master/pkg/controller/remotemachineset/remotemachineset_controller.go#L977-L1003 , we don't have much helpful log messages, only reture true or false. so we can't know which part doesn't work.
