I have two servers connected to the internet. Both can reach each other via ssh.

One should be the kubernetes master node and one i'd like to be a worker node.

How can i connect the worker node only via ssh. I do not want to open other ports than 22.

Edit: @Community Don't know how to limit it more? What is not specific enough? My problem is: i have a vm which should run as a kubernetes worker node. The only port i want to open on that vm is port 22 (ssh). How can i connect such a box as a worker node to a kubernetes cluster, working on another machine where also only port 22 is open. Any Ideas?

Try these steps:

  1. SSH into your VM,

  2. Join the VM as a worker node via join command(should be entered in master node) via:

    kubeadm token create --print-join-command

considering you've installed prerequisites.

  1. Now that you've joined node, in Master/control plane, check if it is added as node via the command:

    kubectl get nodes

P.S Also note that there should be default ports which should be open between Master node and worker node:
