+EXCLUDE_BIND_MOUNTS
+~~~~~~~~~~~~~~~~~~~
+
+Docker has to volumes types. Binds and volumes.
+Volumes are docker volumes (``docker`volume list``).
+Binds are paths mapped into the container from
+the host for example in the ``volumes`` section
+of a service.
+
+If defined all host binds will be ignored globally.
+This is useful when you only care about actual
+docker volumes. Often host binds are only used
+for mapping in configuration. This saves the user
+from manually excluding these bind volumes.
