```
FAILED! => {"attempts": 3, "changed": false, "msg": "Unable to enable service k3s: Failed to enable unit: Access denied\n"}
```
The task never sets become to true, hence failing due to lack of permissions on the user that is executing it by default.
Fixes#17
There appeared to be a race condition where starting all secondary
masters all at once would cause the k3s service to fail on a number of
the other masters. A retry has been added to the task to attempt to
bring them all up until they stop failing.
Fixes#16
This is because without a CNI, nodes will never be ready and the task
will fail. You need to deploy your choice of CNI manually (such as
Calico) then check the state of the cluster using `kubectl get nodes`.
