This is not an official statement from Red Hat or anything, end of disclaimer.
According to Red Hat Satellite 6.3 official docs, these are the mentioned Compute Resources at the moment:
If we as a community cannot maintain any of these, Red Hat will probably interfere and invest engineering resource in doing necessary changes. There is some general confidence that these components are “safe” and moving them into plugins does not need to happen now.
Now for the following resources the support scope is not clear from Red Hat documentation. Satellite 6 customers should reach out to their representatives in order to learn scope of support for these:
Looking into git, Rackspace was mainly maintained by our currently non-active Dominic and Sam and GCE was created by Romain Vrignaud and then random people. I don’t see much activity of currently active community members for these.
Therefore it would be good idea to move both GCE and Rackspace into plugins short term and long term move everything into plugin. That’s our long-term thinking for whole Foreman application for many years already, this does not change. So my suggestion and proposal is actually: Move all Compute Resources to plugins, but start with GCE and Rackspace.
We should also call for maintainers, maybe a blogpost @Gwmngilfen?
