## Developer quick start

The quick start describes how to install and use the operator `mesh` CLI command and/or controller.

### CLI

To build the operator CLI, simply:

```bash
make build
```

			if err != nil {
				return fmt.Errorf("could not build port forwarder for ControlZ %s: %v", podName, err)
			}
			defer portForwarder.Close()
			err = portForwarder.Start()
			if err != nil {
				return fmt.Errorf("could not start port forwarder for ControlZ %s: %v", podName, err)
			}

			ctrlzClient := &ControlzClient{
				baseURL: &url.URL{
					Scheme: "http",
					Host:   portForwarder.Address(),

  // +optional
  optional string concurrencyPolicy = 3;

  // This flag tells the controller to suspend subsequent executions, it does
  // not apply to already started executions.  Defaults to false.
  // +optional
  optional bool suspend = 4;

  // Specifies the job that will be created when executing a CronJob.
  optional JobTemplateSpec jobTemplate = 5;
