I suggest that you create a Dockerfile inside that directory and install docker-compose. That way you will be able to create your own image and after that login to the container which should have everything you need.
This is a basic start. I do warn you however that you have to pay attention because dockerfile build sometimes likes to disperse files and folders differently unlike in your real setup.

This link should shed some light for you: https://docs.docker.com/compose/gettingstarted/

If you have any other question please write it down. I will be happy to answer what I know.
