Hello, thank you for your feedback!

Can you tell me if you have already started PostgreSQL? Or how do you plan to start your PostgreSQL server?

Hello, I added this in docker-compose and the db is deploying and starting fine
db:
image: postgres
restart: always
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD:=mypassword
adminer:
image: adminer
restart: always
ports:
- 8080:8080

1. Log in to your Adminer to create a database. Let's assume your database name is "chatgpt".
2. In the backend-wsgi-server section of the 'docker-compose.yml' file, add the environment variable: DB_URL=postgres://postgres:mypassword@db:port/chatgpt.

Also, make sure that the container services are using the same network.
For example, add the network parameter

networks: 
  - chatgpt_ui_network

to your db service.

Hi,
I need to start postgres without the network parameter in order to create the chatgpt database. If its created and I restart the BE, Im getting connection error in BE: (environment: DB_URL=postgres://postgres:mypassword@localhost:5432/chatgpt)
File "/usr/local/lib/python3.10/site-packages/django/db/backends/postgresql/base.py", line 215, in get_new_connection
connection = Database.connect(**conn_params)
File "/usr/local/lib/python3.10/site-packages/psycopg2/init.py", line 122, in connect
conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Cannot assign requested address
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?

If I start DB with
networks:

• chatgpt_ui_network
  then I can`t connect to adminer to create the chatgpt DB

Perfect, now it works!
I used: environment: DB_URL=postgres://postgres:[email protected]:5432/chatgpt
and:
db:
image: postgres
restart: always
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=mypassword
- POSTGRES_DB=chatgpt
ports:
- 5432:5432

I have a configuration working without using the host machine's internal IP address following the docker compose networking documentation https://docs.docker.com/compose/networking/.
1.) environment: - DB_URL=postgres://postgres:mypassword@db:5432/chatgpt
2.) Docker compose:
db:
image: postgres
restart: always
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=mypassword
- POSTGRES_DB=chatgpt
ports:
- 5432:5432
networks:
- chatgpt_ui_network
