The problem has to do with an invalid environment variable check at https://github.com/Requarks/wiki-v1/blob/master/server/init.js#L16. By default, the environment variable is 1, which is incorrect.

Passing in true or false also yields the wrong result because Docker will always receive environment variables as strings, so the if/else check will always evaluate to true.

This results in the following output in Docker for macOS:
