启动Docker注册表后无法访问http：//172.17.0.2：5000`

Question

在mac系统上，我按照部署文档启动注册：

docker run -d -p 5000:5000 --restart=always --name registry registry:2

它的ip是"IPAddress": "172.17.0.2"，它来自命令docker inspect <cid>

但是我无法远程登录其端口：

$ telnet 172.17.0.2 5000
Trying 172.17.0.2...
telnet: connect to address 172.17.0.2: Can't assign requested address
telnet: Unable to connect to remote host

要么

$ curl http://172.17.0.2:5000
curl: (7) Couldn't connect to server

我对容器进行SSH检查：

$ docker exec -it cda bash
root@cda4c64efd06:/# netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State

Active UNIX domain sockets (servers and established)

Cache-Control: no-cache

root@cda4c64efd06:/#

好像它tcp6没有正常绑定tcp。

哪里错了？

如果使用的是docker-machine，请参阅“ docker-
machine中的端口转发？
”

• 任一端口在VirtualBox级别上转发5000端口（这localhost:5000将起作用）

  VBoxManage controlvm "boot2docker-vm" natpf1 "tcp-port5000,tcp,,5000,,5000";
  

• 或使用由返回的ip $(docker-machine ip <yourMachine>)
