问题描述
这是我的 docker-compose.yml 文件：

'--disable-partition-engine-check','--default_authentication_plugin=MysqL_native_password','--character-set-server=utf8mb4','--collation-server=utf8mb4_unicode_ci','--max_allowed_packet=100M'

当我尝试在 Docker 中使用 wp-cli 时（例如 docker-compose run --rm wpcli plugin list），它收到无法连接到数据库的错误：
Error: `Access denied for user 'username_here'@'192.168.32.5' (using password: YES)`
Error establishing a database connection
This either means that the username and password @R_841_4045@ion in your `wp-config.php` file is incorrect or we can’t contact the database server at `MysqL`. This Could mean your host’s database server is down.
Are you sure you have the correct username and password?
Are you sure you have typed the correct hostname?
Are you sure the database server is running?
If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the wordpress Support Forums. `Access denied for user 'username_here'@'192.168.32.5' (using password: YES)
`
看起来 wp-cli 看到了错误的数据库凭据（username_here 而不是 root）
执行docker-compose run --rm wpcli config list命令的结果：
可能有什么问题？我在网上找遍了，折腾了几个小时，仍然没有找到问题的原因。
