我能够在 Chrome 上呈现虚拟机的公共(public) IP，但无法使用 SSH 连接它，从而引发错误: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。和这个有关系吗？我该如何修复它？
最佳答案
根据你的描述，如果我们想通过ssh连接到docker镜像，我们应该在这个镜像上安装SSH，并为这个镜像打开端口，我将运行centos镜像:
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来连接它:
更新:
我使用 CLI 2.0 创建带有 docker 扩展的虚拟机，并将公共(public) IP 地址更改为静态，并使用命令 sudo docker run -d -p 80:80 nginx 在虚拟机上运行容器。然后使用chrome来测试nginx，它工作正常，我可以使用公共(public)IP和FQDN ssh到Azure VM。
nginx 容器:
jason@MyDockerVM:~$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

尝试使用 FQDN 来 ssh 主机:
