   - Access the system with `sudo -i` (if credentials are not shown, wait for the end of the installation process).
   - if credentials are not show, you can connect to the k8s dashboard, at https://\<your-ip\>:32323/ using the token retrived by `kubectl get secret admin-user -n kubernetes-dashboard -o jsonpath={".data.token"} | base64 -d)` (remember to `sudo -i`)

 I added the script to add more nodes, (on the boostrap node you can run `generate_join.sh` script, to get a base64 code, to use in combination with `join_cluster.sh` script. It was not heavily tested, but ATM it looks working...
