The command $(cat /vagrant/kubeadm-init.out | grep "kubeadm join") is failing because the kubeadm join command in /vagrant/kubeadm-init.out is now multiline like this:

kubeadm join 10.8.8.10:6443 --token 9xdtf5.gar0dim3mbdksw0c \
    --discovery-token-ca-cert-hash sha256:a129fbb0d37d0de15c8428f9f5356e1df9a1a050dd9625d128b5708ce5aa917b 

Hi Artur, many thanks for providing and open sourcing your vagrant kubernetes home lab cluster. ✨

Following your 2 medium posts I'm now with a fully functional cluster on my old/spare notebook.

I can also access kubectl from the host directly - but I'm struggling to setup access from my developer machine (on same home network).
-> From my dev machine I can't telnet against the cluster host on port 6443.

First hurdle seems the vm NAT / port forwarding - which might be configured to be accessible from the host only, but not from external?

See output of (host machine) vboxmanage showvminfo kv-cluster-s_kv-master-0_1585266504407_24845 |grep "NIC":

Further (host machine): sudo netstat -lnp | grep tcp.*LISTEN

Also (host machine): sudo ufw status

Further I think second hurdle might be the cert generated (.kube/config) is restricted to the local vm IP 10.8.8.10.

Is there some particular technical reason you're building this with 4 year old Xenial instead of Focal? Or is that just your personal preference?

With just a few simple changes, it seems to build with Focal and I'm about to test it shortly.

Hello,

I've just done a git clone on this repo and with no changes, done a vagrant up. I then get the below error

The IP address configured for the host-only network is not within the
allowed ranges. Please update the address used to be within the allowed
ranges and run the command again.

  Address: 10.8.8.50
  Ranges: 192.168.56.0/21

Valid ranges can be modified in the /etc/vbox/networks.conf file. For
