"Specified Node IP not found in cloudprovider" about hcloud-cloud-controller-manager HOT 3 CLOSED

Hi @yoshz!
The cloud controller manager queries the server from the API using the hostname.
/v1/servers?name=<hostname> https://docs.hetzner.cloud/#resources-servers-get

The error you are seeing is raised when the kubelets node ip address (kubelet --node-ip) is not included in the ip address list from the cloud provider.
https://github.com/kubernetes/kubernetes/blob/271c267fff12c6cec09d377ac0e6382af661d0e8/pkg/controller/cloud/node_controller.go#L194

I guess you want to ensure all communication runs on your vpn instead of the public network?
Right now I don't see a way for this to work with the cloud controller manager.
There seems to be no way to add additional ip addresses outside of the providers configuration, because kubernetes will override them anyway:
https://github.com/kubernetes/kubernetes/blob/v1.6.2/pkg/kubelet/kubelet_node_status.go#L435

I am open for suggestions, but right now it seems that you need to wait for private networking in the Hetzner Cloud.

I don't mind if traffic from the apiserver / controller-manager to Kubelet goes over the public interface as the traffic is already HTTPS. But I can't seem to get Weave-net to work over the VPN interface as it uses the ip address fetched from the apiserver. Flannel however supports a hardcoded network interface to listen on. Better solution would be just use the build-in encryption of Weave-net.

Anyway, all topics that have nothing to do with this plugin :).
Do you have an ETD for the internal networking?
And will you support for dynamic volume attaching in the future?

Internal networking and block storage are features that will be implemented in the future, but I cannot give you any time frame.
We will post updates about Hetzner Cloud on twitter when we have news: https://twitter.com/hashtag/HetznerCloud?src=hash

I would close this issue for now, if you have further questions, feel free to reopen
