BootStrap a K3S Cluster using k3sup and ansible on a RPI cluster

Notes

k3sup needs to use at least a ecdsa cryptographic key to be able to ssh into the remote hosts.

sh-keygen -t ecdsa
ssh-copy-id -i ~/.ssh/id_ecdsa $SERVER_USER@$SERVER_IP

Need to define docker login creds prior

docker login

# if permission denied
sudo usermod -aG docker $USER
