## Lifespan

Sie können diese Logik beim *Hochfahren* und *Herunterfahren* mithilfe des `lifespan`-Parameters der `FastAPI`-App und eines „Kontextmanagers“ definieren (ich zeige Ihnen gleich, was das ist).

Beginnen wir mit einem Beispiel und sehen es uns dann im Detail an.

Wir erstellen eine asynchrone Funktion `lifespan()` mit `yield` wie folgt:

```Python hl_lines="16  19"

			} else if file.Exists(cniConfigFilePath) {
				t.Fatalf("file %s was not deleted", c.configFilename)
			}

			// check if kubeconfig is deleted
			if file.Exists(kubeConfigFilePath) {
				t.Fatal("kubeconfig was not deleted")
			}

			// check if binaries are deleted
			if file.Exists(filepath.Join(cniBinDir, "istio-cni")) {
				t.Fatalf("File %s was not deleted", "istio-cni")
			}
		})
	}
