Today I installed discourse on a new host, via docker, more or less via this thread:

NOTE: This is for advanced admins This guide assumes you already have Discourse working - if you don’t, it may be hard to tell whether or not the configuration is working. You cannot use ./discourse-setup to set up Discourse if another server is using port 80 or 443. You will need to copy and edit samples/standalone.yml with your favorite tex…

The [pre-install document](https://github.com/discourse/discourse/blob/main/docs/INSTALL.md) says that Postgresql13+ Ruby 3.2+ and Redis 7 should be installed.  
Or actually is just says “Software requirements”.

I do have pg16 running and I installed Redis 7 via snap on Rocky 9.  
I essentially copies the samples/standalone.yml and edited it, added mail server settings and minor changes.

When I `docker ps` or `docker ps -a` I see but 1 container running, the local discourse container.

It might sound like a dumb question, but does the launcher use a pg container and a redis container or are they using the host’s pg and redis installations?
