[Rails Nginx MySQL Docker] Impossible de se connecter à la base

Hello :)

Alors voila j'ai un soucis avec Docker, quand je lance la commande docker compose exec app rails db:migrate j'ai cette erreur:

rails aborted!
ActiveRecord::ConnectionNotEstablished: Can't connect to server on 'database' (115)

Caused by:
Mysql2::Error::ConnectionError: Can't connect to server on 'database' (115)

Tasks: TOP => db:migrate:reset => db:drop => db:check_protected_environments
(See full trace by running task with --trace)

Je ne vois pas d'où ça pourrait venir :/

Voila pour le code
Docker Compose

version: '3'

volumes:
  mysql_data:
  bundle:

services:
  server:
    restart: unless-stopped
    build:
      context: .
      dockerfile: ./docker/server/Dockerfile
    volumes:
      - .:/var/www/app
      - ./docker/server/nginx.conf:/etc/nginx/conf.d/default.conf
    depends_on:
      - app
    ports:
      - 80:80

  database:
    image: mysql:8.0
    env_file: .env.$RAILS_ENV
    restart: unless-stopped
    volumes:
      - mysql_data:/var/lib/mysql
    ports:
      - "5432:3306"

  app:
    restart: unless-stopped
    build:
      context: .
      dockerfile: ./docker/app/Dockerfile
    volumes:
      - .:/var/www/app
      - bundle:/usr/local/bundle
    ports:
      - "3000:3000"
    depends_on:
      - database
    links:
      - database
    env_file: .env.$RAILS_ENV
    tty: true

  mailhog:
    image: mailhog/mailhog
    logging:
      driver: 'none'
    ports:
      - 1025:1025
      - 8025:8025

Config Database

default: &default
  adapter: mysql2
  encoding: utf8mb4
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  port: 5432

development:
  <<: *default
  username: <%= ENV['DB_USER'] %>
  password: <%= ENV['DB_PASSWORD'] %>
  host: <%= ENV['DB_HOST'] %>
  database: <%= ENV['DB_NAME'] %>

Quelqu'un aurait une idée? ^^

EDIT

alors j'ai placé le port 5432 à 3306:3306, ça me fait cette erreur quand je lance db:create:

Created database 'app'
Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)
Couldn't create '' database. Please check your configuration.
rails aborted!
ActiveRecord::ConnectionNotEstablished: Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)

Caused by:
Mysql2::Error::ConnectionError: Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)

quand je lance db:migrate:reset j'ai:

Dropped database 'app'
Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)
Couldn't drop database ''
rails aborted!
ActiveRecord::ConnectionNotEstablished: Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)

Caused by:

Tasks: TOP => db:drop:_unsafe
(See full trace by running task with --trace)

En gros ça arrive à créer la database, ou à la drop pour faire un reset, et tout de suite après il y a l'erreur, du coup je comprends pas, je suis connecté à la base ou pas? :/
