Cool project! I'm actually in the process of rebuilding my personal site as a static site and if I decide to add comments back in (I'm torn on this), this looks like it's going to be pretty high on my list.

As an aside, I was looking at your source on Gitlab, and if I'm reading your Dockerfile correctly, it's a really nice example of using multi-stage builds to build within Docker but produce a final image that doesn't have the full build system in it. This is something I'd been intending to look into for a personal project, so thanks for saving me a bunch of time. :)
