                you want to attach to your new instance.
            machine_type: machine type of the VM being created. This value uses the
                following format: "zones/{zone}/machineTypes/{type_name}".
                For example: "zones/europe-west3-c/machineTypes/f1-micro"

                used subnet will be used.

                address assigned.
            external_ipv4: external IPv4 address to be assigned to this instance. If you specify
                an external IP address, it must live in the same region as the zone of the instance.
                This setting requires `external_access` to be set to True to work.
            accelerators: a list of AcceleratorConfig objects describing the accelerators that will
                be attached to the new instance.
            preemptible: boolean value indicating if the new instance should be preemptible
                or not. Preemptible VMs have been deprecated and you should now use Spot VMs.
            spot: boolean value indicating if the new instance should be a Spot VM or not.

                Possible values: "STOP", "DELETE"
