This can be enabled with:
helm install --name mariadb --set development.enabled=true local/mariadb
This will ensure only a single replica is used and that PVCs (which
require a persistent volume solution) like ceph are not used. Instead
this flag enables a single replica with hostDir storage using the
host path defined in values.yaml which defaults to the following:
/var/lib/openstack-helm/mariadb
