使用通用驱动程序将docker-machine连接到Azure

我有一个基于Docker的Azure部署。 我知道docker-machine有一个Azure驱动程序，可以创build虚拟机并生成证书等。但是我宁愿使用Azure工具（CLI和门户）。

所以我创build了一个VM，并在其上安装了我的公共SSH密钥。 现在我想用docker-machine连接到它。 我添加服务器，以便我可以在docker-machine ls看到它：

 NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default - virtualbox Stopped Unknown serv - generic Running tcp://XX.XX.XX.XX:2376 Unknown Unable to query docker version: Unable to read TLS config: open /Users/user/.docker/machine/machines/serv/server.pem: no such file or directory 

当我尝试设置环境variables时，我看到：

 $ docker-machine env serv Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "XX.XX.XX.XX:2376": open /Users/user/.docker/machine/machines/serv/server.pem: no such file or directory You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'. Be advised that this will trigger a Docker daemon restart which will stop running containers. 

当我尝试重新authentication时，我得到：

 $ docker-machine regenerate-certs serv Regenerate TLS machine certs? Warning: this is irreversible. (y/n): y Regenerating TLS certificates Waiting for SSH to be available... Detecting the provisioner... Something went wrong running an SSH command! command : sudo hostname serv && echo "serv" | sudo tee /etc/hostname err : exit status 1 output : sudo: no tty present and no askpass program specified 

我可以SSH服务器罚款。

这里有什么问题？ 我怎样才能使它工作？
