macos - 在 Mac 上访问 Docker 转发端口

Question

这里有一个相关的帖子:Port mapping in Docker on Mac OSX installed with Docker Toolbox

但它对我不起作用

获取容器的端口

docker 端口 485186e65a5e

8080/tcp -> 0.0.0.0:33360
8088/tcp -> 0.0.0.0:33359
19888/tcp -> 0.0.0.0:33358
50070/tcp -> 0.0.0.0:33357
50075/tcp -> 0.0.0.0:33356
8042/tcp -> 0.0.0.0:33361

检查是否有人监听容器 中的端口

bash-4.1# netstat -alnpt | grep 19888
tcp        0      0 127.0.0.1:19888             0.0.0.0:*                   LISTEN      1094/java   

在容器中做 wget

bash-4.1# wget 127.0.0.1:19888

尝试从主机访问转发端口，不走运... :(((

$docker-machine ip default
192.168.99.100
$ wget 192.168.99.100:33358
--2016-04-11 16:18:04--  http://192.168.99.100:33358/
Connecting to 192.168.99.100:33358... failed: Connection refused.

我做错了什么？

天哪，所需的服务开始于 127.0.0.1 在容器中，这就是为什么从外部世界看不到它的原因。我已经修改了服务配置以从 0.0.0.0 开始，现在我可以访问转发的容器端口
