Machine API Controller reports "unknown instance type"

Solution Unverified - Updated -

Issue

  • We create a new cluster using AWS "c5a.2xlarge" EC2 instances. Although everything runs smoothly the machine-api-controller is showing errors about this particular type of instance:

    E0324 13:16:10.210842       1 controller.go:81] controllers/MachineSet "msg"="Failed to reconcile MachineSet" "error"="unknown instance type: c5a.2xlarge" "machineset"="example-aoj6c-infra-eu-central-1c" "namespace"="openshift-machine-api"
    
  • Are AWS "c5a", "c5ad", "c6g", "c6gd", "g4dn", "i3p", "inf1", "m6g", "m6gd", "r6g", "r6gd" EC2 instances supported?
