Types

type ExecDockerFunc

type ExecDockerFunc func(args ...string) error

TODO: Add a bunch of methods that wrap individual commands. Invocations require the package name anyways, so something like:

docker.Pull(...)

is a lot nicer than

docker.ExecDocker("pull", ...)

var ExecDocker ExecDockerFunc = func(args ...string) error {
	var osCmd *exec.Cmd
	if UseSudo {
		allArgs := append([]string{"docker"}, args...)
		osCmd = exec.Command("sudo", allArgs...)
	} else {
		osCmd = exec.Command("docker", args...)
	}
	osCmd.Stdin = os.Stdin
	osCmd.Stdout = os.Stdout
	osCmd.Stderr = os.Stderr

	return osCmd.Run()
}

type GetDockerFunc

type GetDockerFunc func(args ...string) (string, error)

var GetDocker GetDockerFunc = func(args ...string) (string, error) {
	var osCmd *exec.Cmd
	if UseSudo {
		allArgs := append([]string{"docker"}, args...)
		osCmd = exec.Command("sudo", allArgs...)
	} else {
		osCmd = exec.Command("docker", args...)
	}
	osCmd.Stdin = os.Stdin
	osCmd.Stderr = os.Stderr

	outputBytes, err := osCmd.Output()
	return string(outputBytes), err
}
