Docker-machine 搞乱了主机上的 docker

在 Digital Ocean 中创建 Ubuntu 16.04 Droplet 后，我​​尝试从本地计算机将其与 docker-machine 连接，但服务器的 docker 无法启动。我实际上尝试了两种方式：第一种是在服务器上安装 docker，第二种是不安装 docker，因为当您执行命令时，docker-machine create ...它会安装并覆盖服务器上的任何 docker，最终导致在那里创建失败的 docker 实例。我在防火墙中启用了端口 22、80、443 和 2376。machine create 是否有不在主机中安装 docker 的选项？

$ docker-machine create --driver=generic \
                        --generic-ip-address=XXX.XXX.XXX.XXX \
                        --generic-ssh-user=rinaldi \
                        --generic-ssh-key=C:/Users/[...]/id_rsa \
                        --generic-ssh-port=22 \

这是服务器上的 systemctl -xe

看来这是 docker-machine 0.11 上的一个错误，但它已在 0.12 上修复，如果您需要在 0.11 上工作，那么这里是解决方案。

替换此行/etc/systemd/system/docker.service.d/10-machine.conf然后运行 ​​systemctl daemon-reload 应该可以解决问题。

 # ExecStart=/usr/bin/docker daemon -H ...
 ExecStart=/usr/bin/dockerd -H ...
