+nginx-ingress默认文件传输大小为1M（类似nginx中client_max_body_size），因业务需要，配置为10M。配置方法为在需要大文件传输的ingress中配置注解（annotations）：nginx.ingress.kubernetes.io/proxy-body-size: "10m"
+
+详细配置举例如下：
+
+```yaml
+kind: Ingress
+apiVersion: networking.k8s.io/v1
+metadata:
+  name: test-server-ing
+  namespace: test
+  labels:
+    app: test-server-ing
+  annotations:
+    nginx.ingress.kubernetes.io/proxy-body-size: 10m
+spec:
+  ingressClassName: nginx
+  rules:
+    - host: test.test.com
+      http:
+        paths:
+          - path: /
+            pathType: Prefix
+            backend:
+              service:
+                name: test-server-svc
+                port:
+                  number: 80
+```
