Error deploying kube-dns: no configuration provided

I just installed the core kubernetes cluster manually to better understand the components and automate this installation later. I followed this tutorial: https://kubernetes.io/docs/getting-started-guides/centos/centos_manual_config/

After that, the cluster is completely empty without add-ons. I have already successfully deployed the kubernetes-dashboard, however when I try to deploy kube-dns it does not work with the log:

2017-01-11T15:09:35.982973000Z F0111 15:09:35.978104 1 server.go:55] Failed to create a kubernetes client: invalid configuration: no configuration has been provided

I used the following yaml template for kube-dns without changes, only filling in the cluster IP address: https://coreos.com/kubernetes/docs/latest/deploy-addons.html

What have I done wrong?

While experimenting with kubedns arguments, I added --kube-master-url=http://mykubemaster.mydomain:8080 to the yaml file, and suddenly it turned green.

How did you manage to solve this? For some reason, the container did not know about the owner?

In my case, I had to set the numeric IP address to "-kube-master-url = http: // XXXX: 8080 ". This is in the yaml RC (ReplicationController) file, just like:

  ... spec: containers: - name: kubedns ... args: # command = "/kube-dns" - --domain=cluster.local - --dns-port=10053 - --kube-master-url=http://192.168.99.100:8080
