Serving Docker instance from subdirectory

[dzdn]

Hello! This software is great! However, I am trying to serve it from a subdirectory (e.g. https://example.com/wiki), and as far as I can tell it assumes it is running in the root directory. (Not the local directory, I understand how to specify that location.)

I used the docker-compose.yml described in the installation instructions. I tried setting WIKMD_HOST=https://example.com/wiki, but that had no effect.
