我一直在尝试为dockerized的Wordpress应用程序启用Wordpress多站点网络。
可以通过IP和端口访问该应用程序，如下所示:
http://0.0.0.0:8282
当我在
WP_ALLOW_MULTISITE中启用wp-config.php时，我收到了来自Wordpress的错误消息，即我无法将域名用于端口，例如:8282在这种情况下。所以我在寻找一种方法来从Docker容器而不是
0.0.0.0:8282中公开某些域名我发现了这个例子:
https://www.theimpossiblecode.com/blog/docker-wordpress-multisite-with-subdomains/
正如描述的那样，我仔细研究了该示例以使其起作用。然后，我打算寻找一种方法来为我的特定应用程序实现它。
问题:
我首先公开了服务，如链接页面所述:
https://www.theimpossiblecode.com/blog/docker-expose-service/
我使用了该页面以及运行时随附的
docker-compose.yml$ docker-compose up -d
容器似乎正在工作:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
edaeb215b3eb wordpress:latest "docker-entrypoint.s…" 34 minutes ago Up 34 minutes 80/tcp dockwpress_wordpress_1
5dc6fa8480c6 mysql:5.7 "docker-entrypoint.s…" 34 minutes ago Up 34 minutes 3306/tcp, 33060/tcp dockwpress_db_1
但是，我无法访问:http://dockerwp和
$ dig dockerwp产生以下内容:; <<>> DiG 9.10.6 <<>> dockerwp

在检查容器时，我发现
dockerwp域名已经公开(“com.theimpossiblecode.expose.host”:“dockerwp”行)。$ docker inspect edaeb215b3eb

是什么导致http://dockerwp无法访问？
浏览器显示此错误:
This site can’t be reached dockerwp’s server IP address could not be found.
Did you mean http://docker.com/?
Search Google for docker wp
ERR_NAME_NOT_RESOLVED
谢谢。
最佳答案
http://dockerwp中的dockerwp是不存在的域名。
仅当您将wp站点部署到他们的平台(这会给您一个名为“dockerwp”的子域)时，您的示例才有效。标签om.theimpossiblecode.expose.host由其反向代理读取以创建此效果。
总之，您不能使用此配置设置主机名。最好只使用localhost:port访问您的站点。
