如何在wordpress和nginx中使用docker

Question

我嘗試使用 docker 將 wordpress 與 https 一起使用，但這不起作用，

我有消息：

WordPress | MySQL 連接錯誤：(2002) 連接被拒絕

 version: "3.8"
services:

    db:
        image: mysql:5.7
        volumes:
             - db_data:/var/lib/mysql
        restart: always
        environment:
            MYSQL_ROOT_PASSWORD: somewordpress
            MYSQL_DATABASE: wordpress
            MYSQL_USER: wordpress
            MYSQL_PASSWORD: wordpress

    wordpress:

        environment:

            WORDPRESS_DB_NAME: wordpress
        volumes:
            - ./wordpress:/var/www/html
       
    nginx:
        container_name: nginx
        image: nginx:latest
        restart: unless-stopped
        ports:
            - 80:80
            - 443:443
        volumes:
            - ./nginx/conf:/etc/nginx/conf.d

我今天遇到了同樣的問題，經過多次失敗的嘗試，我認為添加 Exposure 有幫助：

db:
  image: mysql:5.7
  volumes:
    - db_data:/var/lib/mysql
  restart: always
  environment:
    MYSQL_ROOT_PASSWORD: somewordpress
    MYSQL_DATABASE: wordpress
    MYSQL_USER: wordpress
    MYSQL_PASSWORD: wordpress
  expose:
    -"3306"
