There is Sublink but it's written in Java, I don't think I want to deal with Java's runtime environment.
Don't hate Java just for the sake of it.
According to the repository they ship a Dockerfile and use gradle to build it.
Everything should be abstracted for you.
When comparing environments for a program between Java and Python you should probably prefer Java's. Years of experience and build from the ground up for enterprise deployment.
Python module system is hacked together.
It ain't even be fair for python to compare itself in this regard.
Also this project is spot-on within Java's main territory. It makes absolutely sense to me to use Java for such a program.
Plus monitoring/maintaining a Java application is way better then any python program.
