For the Neutron <br>> plugin, I think we can/should conform to Fedora packaging guidelines, <br>> and definitely get that package hosted on RDO directly.<br>> <br>> For the SDN solution in Java, I think we should either allow:<br>> * Relaxed packaging guidelines, recognizing that this is an SDN<br>> solution, and we host Midonet RPMs on RDO site<br>> (i.e. allow jar bundling for this)<br>> * Or allow RDO Manager to pull packages from your repos, not hosted on<br>> RDO site<br>><br>> I think either path should be acceptable.<br><br>Yes, this is exactly right. We want the neutron plugin to be packaged such that we can build it into the overcloud images, but the SDN solution can easily be added post-build with virt-customize or equivalent. I would never recommend anyone go through the full java un-bundling process without a very, very good reason.<br><br>> >> 5. take responsibility for CI<br>> > <br>> > Of course.<br>> <br>> With assistance from the CI team in RDO, of course, to get you started.<br>> <br>> >> As far as these conditions are respected, there should be no <br>> >> problems in accepting MidoNet in RDO.<br>> > <br>> > Getting all these deps packaged will really be a major effort so if <br>> > that's required, it will take a while.
