您未定义用于传入连接的端口，boot2docker将端口80映射到范围49153至65535中的第一个空闲的高范围端口(请参阅操作方法).在boot2docker中 和

You did not define port for incomming connections, and boot2docker maps port 80 to the first free high-range port in range 49153 to 65535 (see how to do it in boot2docker and docker).

这是对我有用的设置(尽管在Windows上，但对于OSX同样适用)，我已将您的应用程序映射到端口8000，请随时进行更改:

Here is the setup that worked for me (on Windows, though, but the same thing is for OSX), I have mapped your application on port 8000, please feel free to change it:

c:\>boot2docker init
Virtual machine boot2docker-vm already exists
c:\>boot2docker up
Waiting for VM and Docker daemon to start...
..........ooo
Started.

Docker client does not run on Windows for now. Please use
    "boot2docker.exe" ssh
to SSH into the VM instead.
c:\>boot2docker ssh -L 0.0.0.0:8000:localhost:8000

Boot2Docker version 1.3.2, build master : 495c19a - Mon Nov 24 20:40:58 UTC 2014
Docker version 1.3.2, build 39fa2fa
docker@boot2docker:~$ docker run -it -p 0.0.0.0:8000:80 --name imgcon33 img33/img33

此设置将您的应用程序映射如下: imgcon33(端口80)-> docker(8000)-> boot2docker(8000)-> localhost(8000)

This setup maps your application like this: imgcon33 (port 80) -> docker (8000) -> boot2docker (8000) -> localhost (8000)

如果您从boot2docker运行curl，那么一个简单的

If you run curl from boot2docker, then a simple

curl localhost:80

应该足够了. 但是，如果要从主机容器(托管boot2docker的容器)访问应用程序，则必须以以下方式运行它:

should be enough. But if you want to access your application from host container (the one that hosts boot2docker), you have to run it as

curl localhost:8000
