**Cảnh báo tiết lỗ**: Tutorial - User Guide:

* Định nghĩa **tham số** từ các nguồn khác nhau như: **headers**, **cookies**, **form fields** và **files**.
* Cách thiết lập **các ràng buộc cho validation** như `maximum_length` hoặc `regex`.
* Một hệ thống **<abbr title="cũng được biết đến như components, resources, providers, services, injectables">Dependency Injection</abbr> vô cùng mạnh mẽ và dễ dàng sử dụng.

## Defaults

As query parameters are not a fixed part of a path, they can be optional and can have default values.

the schema must be added here, otherwise istioctl users will see errors.
Once the schema file is updated, run:

```bash
$ make operator-proto
```

This will regenerate the Go structs used for schema validation.

### Step 4. Update the generated manifests

Tests of istioctl use the auto-generated manifests to ensure that the istioctl binary has the correct version of the charts.

To regenerate the manifests, run:

	opts.AttachControlPlaneFlags(configureCmd)
	return configureCmd
}

// Reads a WorkloadGroup yaml. Additionally populates default values if unset
// TODO: add WorkloadGroup validation in pkg/config/validation
func readWorkloadGroup(filename string, wg *clientnetworking.WorkloadGroup) error {
	f, err := os.ReadFile(filename)
	if err != nil {
		return err
	}
	if err = yaml.Unmarshal(f, wg); err != nil {

			warn, err := v.validateResource("istio-system", "", fromYAML(c.in), writer)
			if (err == nil) != c.valid {
				tt.Fatalf("unexpected validation result: got %v want %v: err=%v", err == nil, c.valid, err)
			}
			if (warn != nil) != c.warn {
				tt.Fatalf("unexpected validation warning result: got %v want %v: warn=%v", warn != nil, c.warn, warn)
			}
		})
	}
}
