I am pleasured to "announce" that we have now a first beta ready.

You can see all the changes in #20.

We would like to get some feedback before releasing this.

Please don't use this for a production environment at the moment!

But how can you use the networks?

1. Create a Network via our CloudConsole (or via CLI)
2. Download the new deployment file with networks support https://github.com/hetznercloud/hcloud-cloud-controller-manager/pull/20/files#diff-5664dce30eb7444c8914c3181f868162
3. Change the cluster-cidr to your pod range
4. Create a new secret with your token kubectl -n kube-system create secret generic hcloud --from-literal=token=<hcloud API token>
5. Create a new secret with the network identifier kubectl -n kube-system create secret generic hcloud --from-literal=network=<hcloud Network_ID_or_Name>
6. Deploy your changed deployment
7. Deploy a CNI (like Cilium kubectl create -f https://raw.githubusercontent.com/cilium/cilium/v1.5/examples/kubernetes/<kubernetes-version>/cilium.yaml - please replace <kubernetes-version> with your version like 1.15)

You should now see the Internal IPs on your nodes and you should see the routes in the CloudConsole.

I made those secrets in one command because kubernet said that secret already created...
kubectl -n kube-system create secret generic hcloud --from-literal=token= --from-literal=network=
I did not find any Network ID so I gave the name in console... (using hetzner cloud console)

step 2 download file from: https://raw.githubusercontent.com/hetznercloud/hcloud-cloud-controller-manager/implement-networks/deploy/development-networks.yaml is better :-)
