docker - 启动dockerregistry后无法访问 `http://172.17.0.2:5000`

Question

在Mac系统上，我按照deploy document启动寄存器:

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

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

但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

或者

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

我通过 ssh 连接到容器来检查它:

$ 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
tcp6       0      0 :::5000                 :::*                    LISTEN
Active UNIX domain sockets (servers and established)
Proto RefCnt Flags       Type       State         I-Node   Path

Cache-Control: no-cache

root@cda4c64efd06:/#

似乎具有约束力 tcp6通常不会tcp 。

哪里错了？

如果您使用的是 docker-machine，请参阅“Port forwarding in docker-machine? ”

• 任一端口在 VirtualBox 级别转发 5000 端口(意味着 localhost:5000 都可以工作)

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

• 或者使用$(docker-machine ip <yourMachine>)返回的IP
