Using Postgres in Rancher 2.1.x pipeline

Hello, everyone!

Quick question: my Django tests need a Postgres database in order to run.
Is there an easy way to set up one using docker, or do I have to manually install and run Postgres?
Using docker images would mean that I need both postgres:latest and python:3.6 images at the same time in my pipeline, and I just don’t know how to do it.

Any help would be appreciated :grin:
