Base docker image? Sounds like you are using docker to run a complete OS.. not sure if that's the best way to do either thing. (Container: run the app, not the OS. Need a virtual OS? run a vm..)
No, I use Docker to run a single process. You still need a base image. Some people use Alpine, some Ubuntu, some Debian and some roll their own. Here are the Debian base images:
