You can also export some additional environment variables prior to running the
``./tools/gate/setup_gate.sh`` that tweak aspects of the deployment.
Rather than ceph, you may use a nfs based backend. This option is especially
useful on old or low spec machines, though is not currently supported with
Linux Kernels >=4.10:

It is also possible to customise the CNI used in the deployment:

@ -76,6 +76,14 @@ Once this has run without errors, you should hopefully have a Kubernetes single
node environment running, with Helm, Calico, appropriate RBAC rules and node
labels to get developing.
Prior to launching you can also optionally set the following environment
variables to control aspects of the CNI used:
.. code:: bash
export KUBE_CNI=calico # or "canal" "weave" "flannel"
export CNI_POD_CIDR=192.168.0.0/16
If you wish to use this environment as the primary Kubernetes environment on
your host you may run the following, but note that this will wipe any previous
client configuration you may have.
