10/09/2024, 7:25 PMThe node addresses are set by the cloud provider, and I’m not aware of any cloud providers that allow this. Generally you can have one internal/external IP of each family (ipv4/v6), one hostname, one InternalDNS, and one ExternalDNS

10/09/2024, 7:26 PMI don’t see anything that restricts you to only having one of each type, but I’ve never seen it done, and I don’t know how things would handle multiple.

10/09/2024, 7:27 PMthere is a lot of code that just scans the address list field, finds the first internalip or externalip of each family and uses that.

10/09/2024, 7:31 PMcloud provider is a thing that runs in the cluster. I’m not talking about the literal company providing the service.

10/09/2024, 7:42 PM"cloud provider" is an incredibly hard term to correctly search for in this respect, can you give me some examples? I've just never heard the term as a component

10/09/2024, 7:45 PMor is that just naturally a sub-component of the kubelet itself?

10/09/2024, 8:46 PMif you google “kubernetes cloud provider” or “kubernetes cloud-controller manager” there is a ton of info on it
