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. + +.. table:: + :class: longtable + + +-----------------------------------------------------------+-------------------+--------------------------------------------------------------------+----------------+ + |Use Case / Requirement |Related OpenStack |Notes |Status | + | |project | | | + +===========================================================+===================+====================================================================+================+ + |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.
