## 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`

option go_package = "k8s.io/api/certificates/v1alpha1";

// ClusterTrustBundle is a cluster-scoped container for X.509 trust anchors
// (root certificates).
//
// ClusterTrustBundle objects are considered to be readable by any authenticated
// user in the cluster, because they can be mounted by pods using the
// `clusterTrustBundle` projection.  All service accounts have read access to
// ClusterTrustBundles by default.  Users who only have namespace-level access

### 3. Configuring Prometheus

#### 3.1 Authenticated Prometheus config

> If MinIO is configured to expose metrics without authentication, you don't need to use `mc` to generate prometheus config. You can skip reading further and move to 3.2 section.

因此，在端点中，只有当用户存在、通过身份验证、且状态为激活时，才能获得该用户：

```Python hl_lines="58-67  69-72  90"
{!../../../docs_src/security/tutorial003.py!}
```

!!! info "说明"

    此处返回值为 `Bearer` 的响应头 `WWW-Authenticate` 也是规范的一部分。

    任何 401**UNAUTHORIZED**HTTP（错误）状态码都应返回 `WWW-Authenticate` 响应头。

    本例中，因为使用的是 Bearer Token，该响应头的值应为 `Bearer`。

    实际上，忽略这个附加响应头，也不会有什么问题。

    之所以在此提供这个附加响应头，是为了符合规范的要求。

    说不定什么时候，就有工具用得上它，而且，开发者或用户也可能用得上。
