Docker 20.10 Breaks Provisioning #215
Description
The current templates don't specify a strict version constraint for the Docker runtime on the host. Docker recently released 20.10 (last night), and parsing docker info doesn't pass the kubeadm tests.
This means that deploying new clusters with CAPP is currently broken.
