I have already googled this and searched in stack-overflow. I have this simple docker-compose setup
version: '3.8'
services:
db:
image: postgres:15-bullseye
restart: always
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=secret
- POSTGRES_DB=combiner
ports:
- '5432:5432'
volumes:
- db_data:/var/lib/postgresql/data
volumes:
db_data:
driver: local
It starts up just fine and I can see the log in the container.
PostgreSQL Database directory appears to contain a database; Skipping initialization

But I cannot connect to the database from outside the container.
I try to use Intellij's database tool and it get a password authentication error.

I am of course running docker-compose on the same computer that I run Intellij on and of course I am giving the correct pasword and user. I should not have to edit the pg_hba.conf file in the container to allow access from outside the container.
Any idea what is going wrong here?
