Important Note: You have to use sudo with all the vagrant commands.

git clone https://github.com/mtyler/vagrant-kubeadm.git

Once the cluster is up, run kubeadm using the provided script on the control plane node

cd vagrant-kubeadm
vagrant ssh cp1
sudo /vagrant/scripts/kubeadm-init-cp1.sh

Follow the instructions in the log output to join remaining nodes

Set Kubeconfig file variable

You can connect to the Vagrant cluster from your local mac terminal by configuring the following.

cd vagrant-kubeadm
cd configs
sudo chmod +r config 
export KUBECONFIG=$(pwd)/config

or you can copy the config file to .kube directory.

cp config ~/.kube/

Validate the cluster access

kubectl get po -n kube-system
