Manage VMs with docker-machine

Manage machines

Create the KVM netwrok

Before a new machine can be created with the docker-machine command, the proper KVM virtual network must be created.

See How to create KVM networks for details.

Create machine

Machine can be created with the docker-machine create command. Most simple usage:

docker-machine create -d <hybervisor driver name> --<hypervisor options> <>

• -d: hypervisor driver. Default value: "virtalbox". For KVM use: "kvm".
• --kvm-network: The name of the kvm virtual network that we would like to use. If this is not set, the new machine will be connected to the "default" KVM virtual network.

Note
Even with the --kvn-network parameter provided, two new interfaces are created for every new VM.

• one for the virtual network, described with the --kvm-network parameter
• docker-machines will create a second, isolated virtual network called "docker-machines", that the new VM is also connected to

# docker-machine create -d kvm --kvm-network "docker-network" manager

Tip
The machine is created under /USER_HOME/.docker/machine/machines/<machine_name> directory
