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.

|Manage container and virtual machine lifecycle with the |Zun_ or nova-docker|Magnum_ can deploy a Container Orchestration Engine (COE), but does |Open |
|same NB API |driver |not provide any lifecycle management operations to the containers | |
| | |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. | |

| | |supported by the COE. | |
| | |As a workaround it is possible to install a registry backend to a VM| |
| | |, but it is more optimal to use the possible backends already | |
| | |available in OpenStack, like Swift_, Cinder_, Glance_ or Glare_. | |
