# [*insecure_registry*]
# Set docker_namespace to INSECURE_REGISTRY, used when a local registry
# is enabled (defaults to false)
#
# [*registry_mirror*]
# Configure a registry-mirror in the /etc/docker/daemon.json file.
# (defaults to false)
#
# [*docker_options*]
# OPTIONS that are used to startup the docker service. NOTE:

#
# [*step*]
# step defaults to hiera('step')
#
# [*configure_libvirt_polkit*]
# Configures libvirt polkit to grant the kolla nova user access to the libvirtd unix domain socket on the host.
# Defaults to true when nova_compute service is enabled, false when nova_compute is disabled
#
# [*docker_nova_uid*]
# When configure_libvirt_polkit = true, the uid/gid of the nova user within the docker container.
