+## Health check endpoint
+
+Gitea comes with a health check endpoint `/api/healthz`, you can configure it in kubernetes like this:
+
+```yaml
+  livenessProbe:
+    httpGet:
+      path: /api/healthz
+      port: http
+    initialDelaySeconds: 200
+    timeoutSeconds: 5
+    periodSeconds: 10
+    successThreshold: 1
+    failureThreshold: 10
+```
+
+a successful health check response will respond with http code `200`, here's example:
+
+```
+HTTP/1.1 200 OK
+
+
+{
+  "status": "pass",
+  "description": "Gitea: Git with a cup of tea",
+  "checks": {
+    "cache:ping": [
+      {
+        "status": "pass",
+        "time": "2022-02-19T09:16:08Z"
+      }
+    ],
+    "database:ping": [
+      {
+        "status": "pass",
+        "time": "2022-02-19T09:16:08Z"
+      }
+    ]
+  }
+}
+```
+

+##運行狀況檢查終端節點
+
+Gitea 附帶了一個運行狀況檢查端點 `/api/healthz`,你可以像這樣在 kubernetes 中配置它:
+
+```yaml
+  livenessProbe:
+    httpGet:
+      path: /api/healthz
+      port: http
+    initialDelaySeconds: 200
+    timeoutSeconds: 5
+    periodSeconds: 10
+    successThreshold: 1
+    failureThreshold: 10
+```
+
+成功的運行狀況檢查回應將使用 HTTP 代碼 `200` 進行回應,下面是示例:
+
+```
+HTTP/1.1 200 OK
+
+
+{
+  "status": "pass",
+  "description": "Gitea: Git with a cup of tea",
+  "checks": {
+    "cache:ping": [
+      {
+        "status": "pass",
+        "time": "2022-02-19T09:16:08Z"
+      }
+    ],
+    "database:ping": [
+      {
+        "status": "pass",
+        "time": "2022-02-19T09:16:08Z"
+      }
+    ]
+  }
+}
+```
