“This is my configuration within docker-compose.yaml:

version: "3.8"

services:
  nestapp:
    build: ./
    ports: 
      - "3000:3000"
    env_file: 
      - .development.env
    depends_on:
      - postgresdb

  postgresdb:
    image: 'postgres'
    volumes:
      - pgdata:/var/lib/postgresql/data
    env_file:
      - .development.env
volumes:
 pgdata: 

docker-compose.yml

In the environment variables, I only have POSTGRES_PASSWORD= root and POSTGRES_DB = root.

Now, I start the container with ‘docker compose up’ and then I go to pgadmin where I register a new server. I enter the IP address that I’m obtaining from the container in the inspect section, port: 5432, maintenance database: e-commerce, username: postgres, and password: root. However, it ends up showing the error: ‘Unable to connect to server: connection timeout expired.

pgadmin register-server

Does anyone know how I can fix this?

I tried reinstalling PostgreSQL since I saw in other posts that this could work, but nothing.”
