### Paso 4: define la **función de la operación de path**

Esta es nuestra  "**función de la operación de path**":

* **path**: es `/`.
* **operación**: es `get`.
* **función**: es la función debajo del "decorador" (debajo de `@app.get("/")`).

```Python hl_lines="7"
{!../../docs_src/first_steps/tutorial001.py!}
```

Esto es una función de Python.

### Features and components

The operator has a very similar structure to istio/installer: components are grouped into features.
`IstioOperatorSpec` defines functional settings at the feature level. Functional settings are those that performs some
function in the Istio control plane without necessarily being tied to any one component that runs in a Deployment.

// name of the function handler passed (this handler must be a method of
// `adminAPIHandlers`).
//
// - sets up call to send AuditLog
//
// While this is a middleware function (i.e. it takes a handler function and
// returns one), due to flags being passed based on required conditions, it is
// done per-"handler function registration" in the router.
