Docker for testing

[aarcex3]

Hi, I'm trying to implement feature #1075.
The Piccolo documentation mentions having a local database for CockroachDB and PostgreSQL. Is it possible to use Docker instead? If so, how can I set it up?
I'm currently having issues getting it to work.

If using Docker, you could:

• Run it using host networking
• Or expose port 5432 to your system

I usually just run Postgres on the bare metal for local testing, using Postgres.app on the Mac, or just apt install on Ubuntu. I can't really help with Windows.
