+# Janitor
+
+### Topology
+
+A Janitor instance will be started on every host that does not match the
+scheduling rule (default is `janitor.exclude=true`).
+
+### Operation
+
+This will run a task daily (by default) that will delete any unused
+image, and any orphaned volume.  The rancher container images are excluded
+from the list of images to clean up.
+
+This will halp to prevent the /var/lib/docker filesystem from filling up
+with old and unused container images.
