-Inspection Store
-================
-
-Ironic inspector can make use of Swift to store introspection data. Not all
-OpenStack deployments feature Swift, so it may be useful to provide a minimal
-HTTP interface that emulates Swift for storing ironic inspector's introspection
-data. This role deploys such an interface using nginx. Note that no
-authentication mechanism is provided.
-
-Requirements
-------------
-
-The host executing the role has the following requirements:
-
-* Docker engine
-* Python ``docker >= 2.0.0``
-
-Role Variables
---------------
-
-Dependencies
-------------
-
-None
-
-Example Playbook
-----------------
-
-The following playbook deploys an inspection store.
-
-    ---
-    - hosts: all
-
-      roles:
-        - role: inspection-store
