我正在开发一些在同一个Amazon EC2实例（AWS EC2实例）下可用的项目，并且我正在尝试为每个项目创建Rocket.Chat。请注意，这些项目中的每一个都有自己的用户库，完全与其他项目隔离，因此每个Rocket.Chat实例也应该被隔离。
我想做的事情有点像：
www.example1.com在chat.example1.com; www.example2.com在chat.example2.com; 请记住，www.example1.com，www.example2.com（...）托管在同一个EC2实例中。此实例具有为这些站点提供服务的Nginx服务器。所以你可以想象我有以下架构：
# Sites content
/var/www/www.example1.com/
index.php
(...)
/var/www/www.example2.com/
index.php
(...)
# Chats content
/var/www/chat.example1.com/
data/
docker-compose.yml
(...)
/var/www/chat.example2.com/
data/
docker-compose.yml
(...)
# Nginx config
/etc/nginx/sites-enabled/www_example1_com
/etc/nginx/sites-enabled/www_example2_com
/etc/nginx/sites-enabled/chat_example1_com
/etc/nginx/sites-enabled/chat_example2_com
当我使用Docker Compose有一个Rocket.Chat实例时，Everythings一切正常，但是有更多实例会让人感到困惑。我尝试将以下端口附加到每个实例：
chat.example1.com
db: 27017
rocketchat: 3000
hubot: 3001
chat.example2.com
db: 27017
rocketchat: 3002
hubot: 3003
当chat.example1.com按预期工作时，事情变得奇怪，但chat.example2.com没有。我发现chat.example2.com正在端口3000中根据它自己的输出进行初始化，因此更改docker-compose.yml文件中的属性ports似乎不起作用。我是否误解了Docker Compose中的一些关键概念，或者它实际上没有按预期工作？
如果我尝试访问这些网站，我会收到以下信息：
chat.example1.com - ＆gt;按预期工作。chat.example1.com:3000 - ＆gt; “安全连接失败”。chat.example1.com:3002 - ＆gt;页面永远不会加载。chat.example2.com - ＆gt; Nginx显示www.example2.com。chat.example2.com:3000 - ＆gt;加载，但似乎使用chat.example1.com Rocket.Chat实例/数据库。chat.example2.com:3002 - ＆gt;页面永远不会加载。发生了什么事？我应该怎么做才能解决这些问题并获得尽可能多的Rocket.Chat实例，每个实例都在我想要的URL中提供？明确使用端口访问聊天没有问题（例如：使用chat.example2.com:3002而不是chat.example2.com，但后者更合适。
注意：出于教学和隐私的原因，我已将所有内容更改为使用chat.example1.com和chat.example2.com，希望您不要错。如果事情让你感到困惑，请告诉我，以便检查是否有错误，拼写错误或提供更多信息。此外，请随意为此问题提出更好的解决方法。

Docker上的Rocket.Chat始终在端口3000上运行。因此，您需要更改文件/var/www/chat.example2.com/docker-compose.yml，以便将主机端口3002绑定到容器端口3000，如下所示：
...
rocketchat:
image: rocketchat/rocket.chat:latest
environment:
- MONGO_URL=mongodb://db:27017/rocketchat
- ROOT_URL=http://chat.example2.com/
- Accounts_UseDNSDomainCheck=True
links:
- db:db
ports:
- 3002:3000
...
