泊坞窗：不能访问容器主机/端口

问题描述：

ps -a 
de3ff650fbef  tasklist-img   "/bin/sh -c 'java -ja" 2 minutes ago  Up 2 minutes    8080/tcp, 0.0.0.0:8080->8081/tcp tasklist-img-01

，不能像本地主机访问：8080 /任务列表

当我检查我有IP地址为172.17 JSON。 0.2，也可达

我的搬运工机器在IP 192.168.99.100 跑我跑容器命令

docker run -d -p 8080:8081 --name tasklist-img-01 tasklist-img

我可以访问http://192.168.99.100:8080/，它是只返回dropwizard指标，http://192.168.99.100:8080/task-list/可达

我也登录

，所以我不能明白的地方是我的微服务？:)））

的为什么'boot2docker'标签？你是不是在操作系统上使用各自的本地Docker？ –

不，我安装了DockerToolbox-1.12.2.exe，是不是更好？:( –

我想如果你不在Windows 10上，那么从来没有想过 –

答

看起来像你映射的端口8081的容器到8080的主机

docker run -d -p 8080:8081

而且有端口监听8080和8081

INFO [2016-11-14 19:32:30,486] org.eclipse.jetty.server.ServerConnector: Started [email protected]{HTTP/1.1}{0.0.0.0:8080} 
INFO [2016-11-14 19:32:30,487] org.eclipse.jetty.server.ServerConnector: Started [email protected]{HTTP/1.1}{0.0.0.0:8081}

您可以访问它，当然，不过这并不是容器的真正8080。你可能需要发布端口范围

docker run -d -p 8080-8081:8080-8081

谢谢，这是错误的，现在它的工作原理就像http://192.168.99.100:8080/task-list –
