Can't create database with postgres and docker - php

Question

I was trying to create a database in my app using command:
php bin/console doctrine:database:create
After that I got an error:
An exception occurred in driver: SQLSTATE[08006] [7] could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?
My docker-compose file looks like that:
version: '3'
services:
php:
container_name: symfony_php
build:
context: ./php
volumes:
- ./symfony/:/var/www/symfony/
depends_on:
- database
networks:
- symfony
database:
container_name: symfony_postgres
image: postgres
restart: always
hostname: symfony_postgres
environment:
POSTGRES_DB: symfony_db
POSTGRES_USER: root
POSTGRES_PASSWORD: root
ports:
- "5432:5432"
volumes:
- ./postgres:/var/lib/postgres
networks:
- symfony
pgadmin:
container_name: symfony_pgadmin
image: dpage/pgadmin4
restart: always
ports:
- "5555:80"
depends_on:
- database
links:
- database
environment:
PGADMIN_DEFAULT_EMAIL: pgadmin4#pgadmin.org
PGADMIN_DEFAULT_PASSWORD: root
networks:
- symfony
nginx:
container_name: symfony_nginx
image: nginx:stable-alpine
build:
context: ./nginx
dockerfile: Dockerfile-nginx
volumes:
- ./symfony:/var/www/symfony
- ./nginx/default.conf:/etc/nginx/conf.d/default.conf
depends_on:
- php
- database
networks:
- symfony

I'm not using any postgres config file, according to Symfony documentation, there's a config line in .env:
DATABASE_URL="postgresql://root:root#127.0.0.1:5432/symfony_db?serverVersion=11&charset=utf8"
I run netstat command and I got:
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN
I think there's a problem with binding my localhost address where my app's server is running to postgres. Does anyone know, how I can fix it?

Answer 1

In docker-compose all services can be reached by their names.
You need to change DB host address to database - as a service name in docker-compose
DATABASE_URL="postgresql://root:root#database:5432/symfony_db?serverVersion=11&charset=utf8"
