To tear-down, the development environment charts should be removed first from
the 'openstack' namespace and then the 'ceph' namespace using the commands from
the `Removing Helm Charts` section. You can run the following commands to
loop through and delete the charts, then stop the kubelet systemd unit and
remove all the containers before removing the ``/var/lib/openstack-helm``
and ``/var/lib/nova`` directory from the host.

the 'nfs' and 'libvirt' namespaces if deploying with NFS backing or bare metal
development support. You can run the following commands to loop through and
delete the charts, then stop the kubelet systemd unit and remove all the

These commands will restore the environment back to a clean Kubernetes
deployment, that can either be manually removed or over-written by
restarting the deployment process.
restarting the deployment process. It is recommended to restart the host before
doing so to ensure any residual state, eg. Network interfaces are removed.
