使用 Wordpress 从 docker 容器连接到 RDS Mysql

Question

使用 docker-compose 启动一个 wordpress 容器，但我想在该容器内连接到 AWS 上的 RDS mysql 实例。我能够设置 wordpress 但无法连接到数据库。我试过将 DB_NAME 变量更改为 _DATABASE。我还可以使用 mac 中的 mysql 命令行来建立有效的连接

version: '2'

services:
   wordpress:
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     environment:
       MYSQL_HOST: "endpoint"
       MYSQL_USER: "user"
       MYSQL_PASSWORD: "pass"
       MYSQL_DB_NAME: "wordpress_docker"
       MYSQL_PORT: 3306
     volumes:
       - ${HOME}:/var/lib/mysql

Answer 1

根据 WordPress 的 documentation

环境名称应该是，

WORDPRESS_DB_HOST=... (defaults to the IP and port of the linked mysql container)
WORDPRESS_DB_USER=... (defaults to "root")
WORDPRESS_DB_PASSWORD=... (defaults to the value of the MYSQL_ROOT_PASSWORD environment variable from the linked mysql container)
WORDPRESS_DB_NAME=... (defaults to "wordpress")
WORDPRESS_TABLE_PREFIX=... (defaults to "", only set this when you need to override the default table prefix in wp-config.php)
