For a [distributed MinIO setup](https://min.io/docs/minio/kubernetes/upstream/operations/installation.html#procedure), where there are multiple pods with different domain names expected to run, you will either need wildcard certificates valid for all the domains or have specific certificates for each domain. If you are going to use specific certificates, make sure to create Kubernetes secrets accordingly.

Die folgenden Argumente werden unterstützt:

* `allowed_hosts` – Eine Liste von Domain-Namen, die als Hostnamen zulässig sein sollten. Wildcard-Domains wie `*.example.com` werden unterstützt, um Subdomains zu matchen. Um jeden Hostnamen zu erlauben, verwenden Sie entweder `allowed_hosts=["*"]` oder lassen Sie diese Middleware weg.

В таком случае этот список должен содержать `http://localhost:8080`, чтобы фронтенд работал корректно.

## Подстановочный символ `"*"`

В качестве списка источников можно указать подстановочный символ `"*"` ("wildcard"), чтобы разрешить любые источники.
