### Validations

Both the `IstioOperatorSpec` and Helm APIs are validated. The `IstioOperatorSpec` API is validated through a
table of validation rules in
[pkg/validate/validate.go](pkg/validate/validate.go). These rules
refer to the Go struct path schema and hence have names with a capitalized first letter.
The Helm values.yaml API is validated in
[validate_values.go](pkg/validate/validate_values.go)

	err := val.Decode(&tmp)
	if err != nil {
		return err
	}

	*r = BatchJobRetry(tmp)
	r.line, r.col = val.Line, val.Column
	return nil
}

// Validate validates input replicate retries.
func (r BatchJobRetry) Validate() error {
	if r.Attempts < 0 {
		return BatchJobYamlErr{
			line: r.line,
			col:  r.col,
			msg:  "Invalid arguments specified",
		}
	}

	if r.Delay < 0 {

* Validate **các cấu trúc phức tạp**:
    * Sử dụng các models Pydantic phân tầng, `List` và `Dict` của Python `typing`,...
    * Và các validators cho phép các cấu trúc dữ liệu phức tạp trở nên rõ ràng và dễ dàng để định nghĩa, kiểm tra và tài liệu hóa thành JSON Schema.
    * Bạn có thể có các object **JSON lồng nhau** và tất cả chúng đã validate và annotated.
* **Có khả năng mở rộng**:

////

/// info

In Pydantic version 1 the method to parse and validate an object was `Item.parse_obj()`, in Pydantic version 2, the method is called `Item.model_validate()`.

///

/// tip

Here we reuse the same Pydantic model.

But the same way, we could have validated it in some other way.
