Ansible playbook for quick Kubernetes setup on a Linux node

Based on a Digital Ocean's tutorial How To Create a Kubernetes 1.11 Cluster Using Kubeadm on Ubuntu 18.04 .

1. Install Ansible on your local machine (not the node you are intending to run Kubernetes).
2. For each of nodes add your ~/.ssh/id_rsa.pub key to the ~/.ssh/authorized_keys on the node so that Ansible can connect via SSH keys.
3. Test that you can actually connect to the node without password by ssh root@ip.or.domain.
4. Then use the initial.yml playbook and run it with ansible-playbook -i hosts ./initial.yml.
5. Follow with ansible-playbook -i hosts ./kube-dependencies.yml
6. Log to your node and confirm that docker --version, kubectl, kubeadm are installed correctly.
