Docker公开服务以实现Docker化的wordpress多站点

时间：2018-12-13 17:23:02

标签： wordpress docker docker-compose

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。

所以我一直在寻找一种方法，该方法如何从Docker容器而不是0.0.0.0:8282公开一些域名

我找到了这个例子：

https://www.theimpossiblecode.com/blog/docker-wordpress-multisite-with-subdomains/

正如所描述的，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/

在运行该页面时，我使用了随附的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会产生以下结果：

; <<>> DiG 9.10.6 <<>> dockerwp

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

$ docker inspect edaeb215b3eb

Did you mean http://docker.com/?
Search Google for docker wp

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（这将为您提供一个名为“ 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。

最后，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。

解决方案是使用Nginx代理服务器，例如https://github.com/jwilder/nginx-proxy

因此，通过使用两个容器，一个是代理，另一个是Wordpress应用程序docker容器，您可以将/etc/hosts的虚拟主机条目添加到127.0.0.1 devwebsite.local中，以用于任何所需的虚拟主机。必须为WP容器VIRTUAL_HOST env配置它们。变量。

以下是示例：https://github.com/djuro/dockerMultisiteWordpress，特别是Dockerfile和docker-compose.yml。

我又使用了2个容器，分别用于数据库和GUI db工具（管理员），但这两个容器都是可选的。
