### Writing controllers

Istio provides a few helper libraries to get started writing a controller. While these libraries help, there are still a lot of subtleties in correctly writing (and testing!) a controller properly.

To get started writing a controller, review the [Example Controller](../../pkg/kube/controllers/example_test.go).

### Controllers overview

			testName:   "success when specific secret name provided",
			objs:       []runtime.Object{kubeSystemNamespace, sa2, saSecret, saSecret2},
			secretName: saSecret.Name,
			name:       "cluster-foo",
			want:       "cal-want",
		},
		{
			testName:        "fail when non-existing secret name provided",
			objs:            []runtime.Object{kubeSystemNamespace, sa2, saSecret, saSecret2},

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

And as the `Response` can be used frequently to set headers and cookies, **FastAPI** also provides it at `fastapi.Response`.
