How can i access to the database from ouside the container but in the same server (local)
I open the port in app.yml
```
expose:
- "4002:5432" #postgres
```
Try to connect from outside with
```plaintext
psql -h 127.17.0.1 -p 4002 -d postgres -U postgres -p ''
psql: could not connect to server: Connection refused
Is the server running on host "127.17.0.1" and accepting
TCP/IP connections on port 5432?
```
What i’m missing ?

Did you rebuild the container after editing `app.yml`? That’s necessary to make changes effective in the running system.

I can’t reproduce the problem. If I do what you describe, it Works For Me. Presumably there’s some other sort of customisation you’ve applied, but not mentioned, that’s causing the problem.
Incidentally, since you’re running on the same machine, you don’t have to expose the port, you can just connect to the Docker-internal IP (`172.17.0.`) on port 5432 and it should work.
