Hi, just popping in! I'm the creator of the Docker image for AMP (I am not affiliated with CubeCoders / AMP, just made the container for fun)
This is the problem of the generic module and stuffing everything into a Docker container -- I can't predict what the generic module would be used for, so the Docker container only has dependencies for the officially supported modules like Minecraft and the Valve games. However, I'm definitely willing to consider adding more dependencies to help you out; I just have to be cautious that it won't be a ton of extra data since it would need to be downloaded by everyone else who uses this image. (Though, I do have a potential solution that could allow you to have whatever dependencies you need without affecting others. More on that later)
What is your goal with the generic module? What are you looking to run? Let's see if we can come up with a solution!
