fe_sendauth：未提供密码 (PG::ConnectionBad) Docker 容器

我按照教程对现有的 rails 应用程序进行了 dockerize。该应用程序在开发环境中成功运行。但是当我尝试以声明env 的方式运行时，我收到了错误消息。我为陈述和开发保留了相同的配置。这是我的相关文件：

数据库.yml

default: &default
  adapter: postgresql
  encoding: unicode
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

development:
  <<: *default
  pool: 10
  timeout: 5000
  database: <%= ENV['DATABASE_NAME'] %>
  username: <%= ENV['DATABASE_USER_NAME'] %>
  password: <%= ENV['DATABASE_PASSWORD'] %>
  host: db
  port: 5432

staging:
  <<: *default
  pool: 10
  timeout: 5000
  database: <%= ENV['DATABASE_NAME'] %>
  username: <%= ENV['DATABASE_USER_NAME'] %>
  password: <%= ENV['DATABASE_PASSWORD'] %>
  host: db
  port: 5432

应用程序.yml

development:
  DATABASE_USER_NAME: 'developer'
  DATABASE_PASSWORD: 'qmwneb10PG'
  DATABASE_NAME: 'concern_box'
staging:
  DATABASE_USER_NAME: 'developer'
  DATABASE_PASSWORD: 'qmwneb10PG'
  DATABASE_NAME: 'concern_box'

docker-compose.yml

version: '3'
services:
  app:
    build: .
    container_name: cb_app_container
  db:
    container_name: cb_db_container
    image: postgres:9.6
    hostname: postgres
    ports:
      - "5432:5432"

docker-compose.stag.yml

version: '3'
services:
  app:
    environment:
      RAILS_ENV: staging
    command: bundle exec rails s -p 80 -b '0.0.0.0'
    ports:
      - "80:80"
    depends_on:
      - db

  db:
    volumes:
      - ./tmp/db:/var/lib/postgresql/data
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql

docker-compose.dev.yml

version: '3'
services:
  app:
    command: bundle exec rails s -p 3000 -b '0.0.0.0'
    stdin_open: true
    tty: true
    volumes:
      - .:/concern-box
    ports:
      - "3001:3000"
    depends_on:
      - db

  db:
    volumes:
      - ./tmp/db:/var/lib/postgresql/data
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql

初始化程序

CREATE USER developer WITH PASSWORD 'qmwneb10PG';
CREATE DATABASE concern_box;
GRANT ALL PRIVILEGES ON DATABASE concern_box TO developer;

我正在使用以下命令docker-compose -f docker-compose.yml -f docker-compose.dev.yml up --force-recreate为开发环境旋转容器并docker-compose -f docker-compose.yml -f docker-compose.stag.yml up --force-recreate作为暂存环境运行。
