How to connect to the database if Lemmy is in a docker container? (lemmy.ml)

I've installed Lemmy via ansible, but I figured out that there are problems with emails and after I've created a user, no verification email came, no login is possible and now I have a ghost account I want to delete.

Because I couldn't find an UI element to purge users in the admin panel, I want to do it over postgresql, but I have no idea how to connect to the Lemmy database over a docker container, only thing I've found is to backup/restore the whole database:

docker-compose exec postgres pg_dumpall -c -U lemmy | gzip > lemmy_dump_date +%Y-%m-%d""%H%M_%S.sql.gz

Thank you for your help.

Oh yeah, try specifying the hostname as localhost (I think it's -h, but --help will confirm it). Psql tries by default to connect to that socket, but in docker it does use it.

Basically, you'll need to specify the hostname and user (and if port, which should just be default, then -p 5432)

It should be

docker exec -it lemmymydomain_postgres_1 psql -h localhost -U lemmy (dbname)

Keeping in mind that you'll need to have the right user and database name, assuming (based on your original comment) lemmy being the username and the db name might also be lemmy

Edit: this should btw just get you into the db, I have no idea of its a good idea or not to delete a user directly from the db, it might cause issues, but I don't have experience with it, but just generally use postgres in docker with other projects

I found a solution here

A warning to people who have the same problem:

On the website there is a command, which will purge all unverified account. If your admin account wasn't verified, it will be purged, too.

Thanks a lot for your help :)

Glad you solved it! Definitely sounds like a better solution than playing around in the db

Well, it is playing around with the db 😀 ... and it could even destroy the whole instance if people don't see the warning I've posted there.
