Adding node 2 to a cluster

Hi, I’m evaluating Kubernetes setup and are trying to create local cluster.

I have 3 Ubuntu VMs with Docker installed.

I’ve setup the first and created a cluster.

I’ve added a node by running the docker run, which has connected and are now part of the cluster.

How do I add node2 to the cluster?

The easy answer is by using the docker run on my 3rd VM.

Unfortunately the node seems to start and run but is not added a node in the cluster as I would have expected?
