Is it within the intended purpose of docker to serve live installations of Wordpress, OpenVPN, Django, or other apps, each in their own container, on a single droplet?
I’d like to combine some services on a single droplet but use docker to make them easy to spin off to their own droplet someday, not sure if this is the right use of Docker, thanks in advance.

Yes, this is right usage for Docker! =)
This is one of main purposes of Docker. You can look at Docker like a Virtual Machine, it’s just much more lightweight, and is much easier to manage once you get into it.
You have many prebuilt images, that will let you run app very fast. You can also build your own images, there are many way to do it like Dockerfile or Docker Compose.
