I currently have SkyDNS that is trying to connect via HTTPS and is using port 443
.
I1221 01:15:28.199437 1 server.go:91] Using https://10.100.0.1:443 for kubernetes master
I1221 01:15:28.199440 1 server.go:92] Using kubernetes API <nil>
I1221 01:15:28.199637 1 server.go:132] Starting SkyDNS server. Listening on port:10053
I want it to use HTTP and port 8080 instead.
My YAML file is :
apiVersion: v1

k8s-app: kube-dns

I understand this might not be a favorable design but is there a way I can change the protocol and port ?
Adding the below like to the kubedns's spec.containers.args section did the trick.
- --kube-master-url=http://master:8080
