[release-2.3] 🐛 Fix deregistering of deleted CAPI Machines #4704

Conversation

k8s-infra-cherrypick-robot

This is an automated cherry-pick of #4701

/assign richardcase

Resolved issue where deleted control planes were still registered in the kube-apiserver load balancer, causing potential disruptions.

We have an issue that there is a gap between the CAPI Machine deletion and the AWSMachine deletion.
In this timeframe the kube-apiserver to the to be deleted control plane is no longer possible, but the deregistering of the LB member will be performed only for AWSMachine deletions.
This PR fixes the gap and also deregisteres the instance if the CAPI Machine is deleted.
