在Mac上访问Docker转发的端口 [英] Access Docker forwarded port on Mac

问题描述

这里有一个相关的帖子：在Docker工具箱安装的Mac OSX上的Docker中的端口映射

There is a related post here: Port mapping in Docker on Mac OSX installed with Docker Toolbox

但是对我来说没有效果

获取容器的端口

Get ports for container

docker port 485186e65a5e

docker port 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

检查有人侦听容器中的端口 / p>

Check that someone listens to ports in container

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

在容器中执行wget

bash-4.1# wget 127.0.0.1:19888
--2016-04-11 14:16:54--  http://127.0.0.1:19888/

尝试从主机访问转发端口，没有运气...：（（（

$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？

推荐答案

Omg，期望的服务开始于 127.0.0.1 在容器中，这就是为什么从外面看不到ld。我修改了服务配置，从0.0.0.0开始，现在我可以访问转发的容器端口

Omg, desired service started on 127.0.0.1 in container, that is why it wasn't visible from outside world. I've modified service config to start on 0.0.0.0 and now I can access forwarded container port
