Create machines using an existing VM/Host with SSH.
This is useful if you are using a provider that Machine does not support directly or if you would like to import an existing host to allow Docker Machine to manage.
The driver will perform a list of tasks on create:
- If docker is not running on the host, it will be installed automatically.
- It will update the host packages (
- It will generate certificates to secure the docker daemon.
- The docker daemon will be restarted, thus all running containers will be stopped.
- The hostname will be changed to fit the machine name.
To create a machine instance, specify
--driver generic, the IP address or DNS
name of the host and the path to the SSH private key authorized to connect
to the host.
$ docker-machine create \ --driver generic \ --generic-ip-address=203.0.113.81 \ --generic-ssh-key ~/.ssh/id_rsa \ vm
The user that is used to SSH into the host can be specified with
--generic-ssh-user flag. This user has to have password-less sudo
If it’s not the case, you need to edit the
sudoers file and configure the user
as a sudoer with
NOPASSWD. See https://help.ubuntu.com/community/Sudoers.
--generic-engine-port: Port to use for Docker Daemon (Note: This flag will not work with boot2docker).
--generic-ip-address: required IP Address of host.
--generic-ssh-key: Path to the SSH user private key.
--generic-ssh-user: SSH username used to connect.
--generic-ssh-port: Port to use for SSH.
Note: You must use a base operating system supported by Machine.
