Generic driver for provisioning CentOS machine does not work: "operation not supported by device"

[ppadala]

I am trying to call docker-machine through os/exec and found that docker-machine is using -t option for external client and OutputWithPty for NativeClient. Both require a pty to be present (as I understand) and os/exec doesn't come with a pty. See the test program and output below. I also tried using github.com/kr/pty and assign a tty, but couldn't get it work. Any comments are welcome.

package main

import (
        "os/exec"
        "fmt"
)

func RunCmd(cmd string, args []string) (string, error) {
        var (
                cmdOut []byte
                err    error
        )

        fmt.Println(cmd, args)
        if cmdOut, err = exec.Command(cmd, args...).CombinedOutput(); err != nil {
                return string(cmdOut), err
        }

        output := string(cmdOut)
        fmt.Print(output)
        return output, nil
}

func main() {
        cmdOut, err := RunCmd("docker-machine",
                []string{"-D", "create", "-d", "generic", "--generic-ip-address", "10.1.10.12", "bot1"})
        fmt.Println(cmdOut)
        fmt.Println(err)

}

You will want to check the provider to make sure the machine and associated resources were properly removed.
