【问题描述】：

我在 docker 容器中运行 media wiki 1.35.2 并收到错误

 Original exception: [733e024ba16cc597716794fe] / Wikimedia\Rdbms\DBConnectionError   from line 1420 of /var/www/html/includes/libs/rdbms/loadbalancer/LoadBalancer.php: Cannot access the database: Unknown error ()
 Backtrace:
#0 /var/www/html/includes/libs/rdbms/loadbalancer/LoadBalancer.php(934): Wikimedia\Rdbms\LoadBalancer->reportConnectionError()

LocalSettings.php

$wgDBtype = "postgres"; 
$wgDBserver = "database";
$wgDBname = "my_wiki"; 
$wgDBuser = "wikiuser"; 
$wgDBpassword = "xxx"; 

$wgDBport           = "5432";
//$wgDBmwschema       = "mediawiki";
//$wgDBts2schema      = "public";

我可以从 mediawiki 容器内通过 psql 连接到数据库。错误消息与数据库类型无关（也尝试过 mariadb - 来自https://hub.docker.com/_/mediawiki）或者即使我关闭了 postgresql12 容器我也尝试在 LocalSettings.php 中使用 IP 而不是主机名。

（类似于 Mediawiki with docker. Can't locate LocalSettings.php and cannot access database)

码头工人撰写：

mediawiki:
  image: mediawiki:latest
  restart: unless-stopped
  ports:
    - 8080:80
  volumes:
     - /var/www/html/images
    # After initial setup, download LocalSettings.php to the same directory as
    # this yaml and uncomment the following line and use compose to restart
    # the mediawiki service
     - ./wiki/LocalSettings.php:/var/www/html/LocalSettings.php

networks:
  default:
    external:
      name:  ....
