通过主机名访问我的 Dockerized 网站

Question

在我的本地主机上，我有一个 Docker 容器服务于一个 PHP 网站，我可以在我的浏览器中看到它 http://localhost/learnintouch/www/learnintouch.com/ 但我更愿意以这种方式访问它 dev.learnintouch.com/ 如果可能的话。

我尝试运行用 docker run -d --name learnintouch -p 80:80 -p 443:443 --add-host "dev.learnintouch.com":127.0.0.1 -v /home/stephane/dev/php/learnintouch:/usr/bin/apache/htdocs/learnintouch stephaneeybert/learnintouch 连接我的容器，但这还不够。

容器 Apache 服务器使用以下虚拟主机：

<VirtualHost *:80>
  ServerName dev.learnintouch.com
  ServerAlias dev.learnintouch.com
  DocumentRoot /usr/bin/apache/htdocs/learnintouch/www/learnintouch.com
  CustomLog logs/learnintouch-access_log combined
  <Directory "/usr/bin/apache/htdocs/learnintouch/www/learnintouch.com">
    Include /usr/bin/apache/htdocs/learnintouch/engine/setup/url_rewrite.conf
  </Directory>
  AddDefaultCharset UTF-8
</VirtualHost>

我的主机的 /etc/hosts 包含：

127.0.0.1   localhost
127.0.1.1   stephane-ThinkPad-X301

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

我运行一个Docker版本：

 Version:      1.12.1
 API version:  1.24
 Go version:   go1.6.3

您使用 --add-host 选项传入的额外主机将修改容器的 /etc/host，而不是主机本身上的文件。为了进行测试，您需要修改主机运行上的 /etc/host 您的浏览器。对于生产，您需要更新 DNS 以指向 docker 主机（或包含 docker 主机作为其目标的负载均衡器）。
