My homelab setup

Run ansible for kubernete

ansible-playbook playbooks/setup-kubernetes

Copy kubectl config from master

scp -r masterIP:~/.kube/config localIP:

Ex: scp -r master:~/.kube/config ~/.kube/config_mycluster

Note: Set eth1 to internal Ip ( default is eth0 - 10.0.2.15) for each node when use Vagrantfile (fix issue that cannot exec on a pod)

Add following setting to Vagrantfile

    node.vm.provision "shell",
      run: "always",
      inline: "route add default gw 192.168.11.1"
    # node.vm.provision "shell", path: "bootstrap_kmaster.sh"

    # delete default gw on eth0
    node.vm.provision "shell",
      run: "always",
      inline: "eval `route -n | awk '{ if ($8 ==\"eth0\" && $2 != \"0.0.0.0\") print \"route del default gw \" $2; }'`"

Specific internal Ip in setting file (eg : 20-extra-args.conf.j2)
