+Where the nodes layout `default` is that is given in the example inventory file.
+And the `separate` layout is when there is only node of each type, which is a kube master,
+compute and etcd cluster member.
+
+Note, the canal network plugin deploys flannel as well plus calico policy controller.
+
+Hint: the command
+```
+bash scripts/gen_matrix.sh

+will (hopefully) generate the CI test cases from the current ``.travis.yml``.
