+OpenRetriever Gap Analysis with OpenStack
+=========================================
+This section provides a gap analyzis between the targets of OpenRetriever for
+release Euphrates (E) or later and the features provided by OpenStack in release
+Ocata. As the OPNFV and OpenStack releases tend to change over time this
+analyzis is planned to be countinously updated.
+During the analyzis all OpenStack projects considered.
+
+(**Editors note:** Maybe we should define a scope of OpenStack projects which is
+considered. All OpenStack projects can mean anything.)
+
+The following table lists the use cases / feature requirements of container
+integrated functionality, and its gap analysis with OpenStack.

+ | | |deployed in the COE. | |
+ | | |Zun_ provides lifecycle management support for the containers | |
+ | | |deployed in the COE via Nova API, but not all COE API operations are| |
+ | | |supported. | |
+ | | |nova-docker driver provided support for container lifecycle | |
+ | | |management without a COE (and Magnum), but it was deprecated due to | |
+ | | |lack of community support. A fork of the original nova-docker driver| |
+ | | |is maintained by the Zun team to provide support for the sandbox | |
+ | | |containers. | |
+ | | |**Note:** Support for this is not targeted in OPNFV release E. | |

+ | | |As a workaround it is possible to install a registry backend to a VM| |
