Ansible playbook is located in aws folder
Add the AWS instances IPs and ssh key path to aws-hosts file

# check the ansible playbook syntax
ansible-playbook --syntax-check kubernetes-cluster-1M-2W.yaml -i aws-hosts
# run the playbook
ansible-playbook kubernetes-cluster-1M-2W.yaml -i aws-hosts
The join command for worker nodes to join the master node is in the cluster-join.txt file created by kubeadm init command and is located in the home directory of your Master node
- Use ansible variables to pass the join command from Manager to Worker Nodes. This will eliminate the need for user to manually run the join command after
