Docker OSX无法通过IP地址访问容器
我在Mac上遇到了Docker的一些奇怪的问题。 当我build立一个容器，我无法通过容器的IP地址访问它。
我和Docker Quickstart Terminal一起安装了Docker。 我已经创build了一个基本的Dockerfile来testing：
FROM ubuntu:14.04 MAINTAINER Me <me@gmail.com> RUN apt-get update RUN apt-get install -y nginx RUN echo "Testing" > /usr/share/nginx/html/index.html CMD ["nginx", "-g", "daemon off;"] EXPOSE 80
我build立与：
docker build -t james/nginx .
然后运行：
docker run -d james/nginx
在这个例子中，我没有使用-p 80:8080 ，因为此刻我只是想知道为什么我不能通过容器IP访问。 我甚至不能ping通它。
该容器已经给了标题admiring_snyder （一定要喜欢Docker的命名scheme）。 所以我运行docker inspect admiring_snyder获取机器的IP地址：

其中显示了IP地址：
"IPAddress": "172.17.0.4"
我无法连接到这个IP地址。 我有一种感觉，这是与在docker上运行的虚拟机（显然是没有别的办法）。 但是，我不知道如何解决这个问题。
虚拟机的IP为192.168.99.100 。 我从docker-machine ip default得到了这个。
有什么build议？
您可以使用端口映射启动映像;
docker run -d -p 8080:80 james/nginx
这会将docker vm上的端口8080映射到docker容器中的port 80，正如可以在PORTS下的docker ps看到的那样;
