I would just have your Dockerfile specify a FROM image of the stock
Ubuntu 16.04 image (or whatever your favorite base Linux distro is). For
example our Dockerfile at work starts with:

FROM ubuntu:16.04

We then tell it to apt-get update and apt-get install <many things>

The same way you'd handle it on any other server.

It may help to think of docker as just another VM, just like running one
in VirtualBox or VMWare. The technical underpinnings matter very little.
