示例1: importImageAndFetchHashAsGid

func importImageAndFetchHashAsGid(t *testing.T, ctx *testutils.RktRunCtx, img string, fetchArgs string, gid int) string {
	// Import the test image into store manually.
	cmd := fmt.Sprintf("%s --insecure-options=image,tls fetch %s %s", ctx.Cmd(), fetchArgs, img)

	// TODO(jonboulle): non-root user breaks trying to read root-written
	// config directories. Should be a better way to approach this. Should
	// config directories be readable by the rkt group too?
	if gid != 0 {
		cmd = fmt.Sprintf("%s --insecure-options=image,tls fetch %s %s", ctx.CmdNoConfig(), fetchArgs, img)
	}
	child, err := gexpect.Command(cmd)
	if err != nil {
		t.Fatalf("cannot create rkt command: %v", err)
	}
	if gid != 0 {
		child.Cmd.SysProcAttr = &syscall.SysProcAttr{}
		child.Cmd.SysProcAttr.Credential = &syscall.Credential{Uid: uint32(nobodyUid), Gid: uint32(gid)}
	}

	err = child.Start()
	if err != nil {
		t.Fatalf("cannot exec rkt: %v", err)
	}

	// Read out the image hash.
	result, out, err := expectRegexWithOutput(child, "sha512-[0-9a-f]{32,64}")
	if err != nil || len(result) != 1 {
		t.Fatalf("Error: %v\nOutput: %v", err, out)
	}

	waitOrFail(t, child, 0)

	return result[0]
