Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: Autoscaler expects provider IDs across Node and Machine objects to be an exact match. This may not be the case if the Machine configuration specifies a resource group name with mixed casing. Consequence: The autoscaler believes the Machine never gets a node and terminates the machine after a 15 minute period Fix: Sanitise the user input and convert the resource group to lowercase Result: Provider IDs will always match regardless of casing on user input

creating an IPI Azure cluster, then modifying the MachineSet to set the resourceGroup to a capitalised version, then scaling up some Machines in that MachineSet, machines could join the cluster.

$ oc edit machineset zhsun616azure1-r62jc-worker-eastus23
resourceGroup: zhsun616azure1-r62jc-RG

$ oc get node
