[RFC] containers module in refpolicy

[RFC] containers module in refpolicy

[Kenton Groombridge]

At this time refpolicy does not have much (if any) support for various
container runtimes such as docker or podman. An issue was raised on
container-selinux[1] about the possibility of allowing it to be built
against refpolicy, but the question came up of whether or not it would
be a better idea to instead introduce such a module specifically in
refpolicy. Upstream seems to be open to the idea of making
container-selinux work with refpolicy, but I worry that the task of
maintaining the module will be more work in the long run.

What are your thoughts?

We have more than a few policy modules that aren't used by the regular 
contributors to refpolicy and which aren't well maintained.  Adding one more 
is no big deal.

Generally having a module in upstream policy that does most of what you want 
is better than nothing, you can just have a local module to do the remainder.  
When the types needed are defined it removes the potential compatibility 
issues of different implementations.

Where is the [1] reference?

Looks like I forgot to include it. The upstream issue is here:
