## Healthcheck Probe

MinIO server has two healthcheck related un-authenticated endpoints, a liveness probe to indicate if server is responding, cluster probe to check if server can be taken down for maintenance.

- Liveness probe available at `/minio/health/live`

Bei HTTP Basic Auth erwartet die Anwendung einen Header, der einen Benutzernamen und ein Passwort enthält.

Wenn sie diesen nicht empfängt, gibt sie den HTTP-Error 401 „Unauthorized“ zurück.

Und gibt einen Header `WWW-Authenticate` mit dem Wert `Basic` und einem optionalen `realm`-Parameter („Bereich“) zurück.

Dadurch wird der Browser angewiesen, die integrierte Eingabeaufforderung für einen Benutzernamen und ein Passwort anzuzeigen.

                    Authentication result = new Authentication(
                            authCtx.get(AuthenticationContext.USERNAME), authCtx.get(AuthenticationContext.PASSWORD));
                    result.setPrivateKey(authCtx.get(AuthenticationContext.PRIVATE_KEY_PATH));
                    result.setPassphrase(authCtx.get(AuthenticationContext.PRIVATE_KEY_PASSPHRASE));
                    authCtx.close();
