Generic

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 (apt-get update, yum update…).
• 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.

Example

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

Sudo privileges

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 privileges. 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.

Options

• --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.
