Background

MAPI MachineSets have label selector to machine Label mapping. There are CAPI equivalents for these labels. During MachineSet/Machine conversion we should convert to the MAPI/CAPI equivalent.

machine.openshift.io/cluster-api-cluster: <clusterID>
<--->
cluster.x-k8s.io/cluster-name: <clusterID>

machine.openshift.io/cluster-api-machine-type: <role>
machine.openshift.io/cluster-api-machine-role: <role>
<--->
node-role.kubernetes.io/<role>: ""

machine.openshift.io/cluster-api-machineset: <clusterID>-<role>-<region>
<--->
cluster.x-k8s.io/set-name:<clusterID>-<role>-<region>

Steps

• Look into upstream code to determine if there are any possible values for the above labels that we have not accounted for. 

• Determine if there is difference between MAPI type and role label and if they can be consolidated into one CAPI label.
• Add the conversion to the conversion library.

Stakeholders

• Cluster Infra
