Docker install: is it possible to access to postgresql and redis

Hello, I’m using sentry on a vos since 2 months. It’s quite interesting but I would like to do some custom queries that are impossible to do from GUI. So is it possible to connect to postgresql or redis from docker installation?
Thanks for help

Yes, you should be able to. However, that depends on the set up you’re running. In case you’re running the entire stack (using docker-compose, for instance) on one single machine, you might’ve to change the way the networking is done.

For starters, go through the documentation on Docker networking here: https://docs.docker.com/network/
It’s a little lengthy and detailed, but if you need something a little terse, I wrote about this a little bit here, and there are much better articles elsewhere on the internet too.

Depending upon the networking setup, you’ll have a way to connect to psql or have a similar way to connect to the underlying Postgres instance that runs as a container.
