You can use the RUN keyword in order to execute stuff.
If it's shell command you want to run, you can run bash -c with your shecl script.

See some examples and doc here:. https://docs.docker.com/engine/reference/builder/#run

This can provide you with a shell inside the container:

docker exec dockernamehere bash
