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 .

    这次,我们可以使用SSH来连接它:

    更新:

    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 Public IPFQDN 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
