我尝试通过以下 URL 的浏览器访问 Mercure 的中心但没有成功：http://locahost:3000 => ERR_CONNECTION_REFUSED

我使用 Docker 进行开发。这是我的 docker-compose.yml ：

# docker/docker-compose.yml
version: '3'

services:
  database:
    container_name: test_db
    build:
      context: ./database
    environment:
      - MYSQL_DATABASE=${DATABASE_NAME}
      - MYSQL_USER=${DATABASE_USER}
      - MYSQL_PASSWORD=${DATABASE_PASSWORD}
      - MYSQL_ROOT_PASSWORD=${DATABASE_ROOT_PASSWORD}
    ports:
      - "3309:3306"
    volumes:
      - ./database/init.sql:/docker-entrypoint-initdb.d/init.sql
      - ./database/data:/var/lib/mysql

  php-fpm:
    container_name: test_php
    build:
      context: ./php-fpm
    depends_on:
      - database
    environment:
      - APP_ENV=${APP_ENV}
      - APP_SECRET=${APP_SECRET}
      - DATABASE_URL=mysql://${DATABASE_USER}:${DATABASE_PASSWORD}@database:3306/${DATABASE_NAME}?serverVersion=5.7
    volumes:
      - ./src:/var/www

  nginx:
    container_name: test_nginx
    build:
      context: ./nginx
    volumes:
      - ./src:/var/www
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/sites/:/etc/nginx/sites-available
      - ./nginx/conf.d/:/etc/nginx/conf.d
      - ./logs:/var/log
    depends_on:
      - php-fpm
    ports:
      - "8095:80"

  caddy:
    container_name: test_mercure
    image: dunglas/mercure
    restart: unless-stopped
    environment:
      MERCURE_PUBLISHER_JWT_KEY: '!ChangeMe!'
      MERCURE_SUBSCRIBER_JWT_KEY: '!ChangeMe!'
      PUBLISH_URL: '${MERCURE_PUBLISH_URL}'
      JWT_KEY: '${MERCURE_JWT_KEY}'
      ALLOW_ANONYMOUS: '${MERCURE_ALLOW_ANONYMOUS}'
      CORS_ALLOWED_ORIGINS: '${MERCURE_CORS_ALLOWED_ORIGINS}'
      PUBLISH_ALLOWED_ORIGINS: '${MERCURE_PUBLISH_ALLOWED_ORIGINS}'
    ports:
      - "3000:80"

我已成功执行：

docker-compose up -d

码头工人 ps -a ：

CONTAINER ID   IMAGE                            COMMAND                  CREATED       STATUS       PORTS                                                      NAMES

我可以通过 http://localhost:8095 访问我的 Symfony 应用程序，但我不知道应该通过哪个 URL 访问 Mercure 的中心。

谢谢你的帮助 ！
