+    A new option has been added allowing deployers to disable any and all
+    containers on a given host. The option `no_containers` is a boolean
+    which, if undefined, will default to *false*. This option can be added
+    to any host in the `openstack_user_config.yml` or via an override in
+    `conf.d`. When this option is set to *true* the given host will be
+    treated as a baremetal machine. The new option mirrors the existing
+    environmental option `is_metal` but allows deployers to target
+    specific hosts instead of entire groups.
