So I have a working alpine-based container for XMR. The main issue from a “production” point of view, is that it depends on “edge” currently, so I don’t think I’d feel comfortable making that available generally until 3.6 were released and we have something more static to test against.
I’m having a look at the CMS now, but that’s far more complex. It’s something we’re looking at to go with PHP7 support however.
