@icedquinn just use a gitlab account (the one qoto offers works or gitlab.com or your own).. it has docker repositories built-in... though not sure we enabled it on QOTO or not I'd need to check. But I can enable it for you if not.
@icedquinn my own blog is generated from markdown (with support for many other formats) through the CI at our gitlab.. it took all of like 3 lines of code to make that work, so its very trivial if you wanted to do that.
