Question

我能够在Chrome上呈现虚拟机的公共IP，但无法使用SSH连接它，引发错误：连接到主机xxx.xxx.xxx.xx端口22：连接被拒绝。当我在Portal上检查虚拟机时，没有为其分配安全组。这与此有关吗？我该如何解决？

根据你的描述，如果我们想要ssh到docker镜像，我们应该在这个图像上安装SSH，并为这个图像打开端口，我将运行centos image例如：

docker pull centos:centos6
docker run -i -t centos:centos6
yum install openssh-server openssh-client(install ssh)
chkconfig sshd on
passwd(reset root password)
exit
docker commit 332b19ca916c centos/centosssh  (commit this image)

docker run -i -t -d -p 50001:22 centos/centosssh  (NAT for this container)
docker attach containerid  (connect this container)
vi /etc/ssh/sshd_config  (modify sshd config)

change UsePAM to no

service sshd start

然后在Azure NSG中打开端口50001。

这一次，我们可以使用SSH连接它：

我使用CLI 2.0创建具有docker扩展名的VM，并将公共IP地址更改为 static ，并使用命令sudo docker run -d -p 80:80 nginx在VM上运行容器。然后使用chrome来测试nginx，它工作正常，我可以使用公共IP 和 FQDN ssh到Azure VM。 nginx容器：

jason@MyDockerVM:~$ docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                         NAMES
61e10ebb6d22        nginx               "nginx -g 'daemon ..."   4 minutes ago       Up 4 minutes        0.0.0.0:80->80/tcp, 443/tcp   kind_leavitt

尝试使用FQDN来ssh主机：

[c:\~]$ ssh jason@mypublicdns.eastus.cloudapp.azure.com

尝试使用公共IP地址来ssh主机：
