Issue on 2019-11-05 version Lab 3.2 problem
The excercise regards the configuration of a local docker repository.
I am doing the lab in a bare-metal cluster on Ubuntu 18.04 configured via the k8sMaster and k8sSecond scripts.
Two nodes, one of which is an untaint master.
The problem occurs at the step 21, where we are supposed to access the "registry" service via curl directly from the master node's shell.
In my case the connection hangs until the timeout is reached, I have also disabled the ufw so there shouldn't be any firewall problem as mentioned in the lab.
Being the "registry" service of ClusterIP type, I was not surprised of being unable to access it directly from the shell as I knew that ClusterIP services are accessible only from inside kubernetes.
But from the description of the step 21 it seems that we should be able to access the service IP:Port directly from the shell.
Am I doing anything wrong?
Could anyone confirm that, from the master machine's shell, a ClusterIP svc address and ports should be directly reachable?
