Question

我尝试从一个docker容器ssh到互联网，但它没有任何错误就卡住了。我在详细模式下运行ssh，这就是结果：

root@bac91c5282c7:/opt# ssh -v git@git.foo.com -i /root/.ssh/id_rsa
OpenSSH_6.7p1 Debian-5+deb8u3, OpenSSL 1.0.1t  3 May 2016

我的问题与此question类似，但问题是由于Gateway和IPAddress为空，因此网桥配置不正确。但就我而言，一切似乎都是正确的。我也可以telnet到任何远程机器上我想要的任何端口。该问题与ssh具体相关。

foo@bar:~/code$ ip addr | grep "docker"
7: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default 
    inet 172.17.0.1/16 scope global docker0

docker network：

foo@bar:~/code$ docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
e8f23bd035df        bridge              bridge              local

c6ac46615046        code_default    bridge              local

docker inspect的输出：

                }
            }
        }
    }

值得一提的是，此问题仅在特定服务器上发生。我已经在我的笔记本电脑或VPS上测试了这个容器，但没有遇到任何问题。

知道如何解决这个问题吗？
