Can I expose nextcloud-aio-database port to host?

[joezimjs]

I'm barely getting by with my Docker knowledge, so I'm not really sure how to set it up or if it's possible with the way things are set up, but is there a way I can open up the nextcloud-aio-database's port to the host? I have a pgAdmin desktop client and I'd rather not set up the Docker version too if I can help it, so I'd like that desktop client to be able to connect to the Postgres DB in that container.

No, you cannot

OK, so I need to use the pgadmin Docker setup, right? I don't really understand how to do what the Readme says:

For the container to connect to the aio-database, you need to connect the container to the docker network nextcloud-aio and use nextcloud-aio-database as database host, oc_nextcloud as database username and the password that you get when running sudo docker exec nextcloud-aio-nextcloud grep dbpassword config/config.php as the password.

How do I "connect the container to the docker network nextcloud-aio and use nextcloud-aio-database as database host"?

Why are you trying to install pgadmin in the first place if I may ask?
