Some questions about architecture and deployment

I have three fairly small django apps which will share a single postgres database, but which I want to maintain as separate apps, since they do completely different things with different subsets of the tables in the db. What is the best way to run this setup on a vps? A lot of the blog posts etc. I've found seem to automatically assume i want one docker container per app, but that seems like a lot of overhead with everything running the same stack.
