This example program demonstrates the fundamental operations for managing on Deployment resources, such as Create, List, Update and Delete.

Code for this is available here and the whole documentation for Go client for Kubernetes..

Or you can just write your own function to deploy the yaml as a parameter.

func cellDeploy(pathToFileName string) error {
    cmd := exec.Command("kubectl", "apply", "-f", pathToFileName)
    stdoutReader, _ := cmd.StdoutPipe()
    stdoutScanner := bufio.NewScanner(stdoutReader)
    go func() {
        for stdoutScanner.Scan() {
            fmt.Println(stdoutScanner.Text())
        }
    }()
    stderrReader, _ := cmd.StderrPipe()
    stderrScanner := bufio.NewScanner(stderrReader)
    go func() {
        for stderrScanner.Scan() {
            fmt.Println(stderrScanner.Text())
        }
    }()
    err := cmd.Start()
    if err != nil {
        fmt.Printf("Error : %v \n", err)
        os.Exit(1)
    }
    err = cmd.Wait()
    if err != nil {
        fmt.Printf("Error: %v \n", err)
        os.Exit(1)
    }

    return nil
}
