How to run it?

⚠️ The following step should be run in root mode, and be careful

Master node

1. Run bash install.sh to install k8s utilities
2. Run bash master.sh to create cluster
3. Run cat kubeadm-init.log to see the token, hash token and ip information (this will be used later on).

Worker node

1. Run bash install.sh to install k8s utilities
2. Create token.sh with the following content

   export CONTROL_PLANE_IP=<according to kubeadm-init.log>
   export TOKEN=<according to kubeadm-init.log>
   export HASH_TOKEN=<according to kubeadm-init.log>
   

3. Run source token.sh to load the environment variable
