1. 报错信息
   nginx-ingress-controller限制上传文件大小为1M如果上传文件大于1M则会在浏览器报以下错误

# Request Entity Too Large

2. 解决方法
   修改ingress配置文件增加以下配置

 annotations:
    #nginx.org/client-max-body-size: "4096m"
    nginx.ingress.kubernetes.io/proxy-body-size: 4096m

一个完整的配置文件如下

# cat ingress.yaml 
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  generation: 1
  name: ingress
  namespace: default
  annotations:
    #nginx.org/client-max-body-size: "4096m"
    nginx.ingress.kubernetes.io/proxy-body-size: 4096m
spec:
  rules:
  - host: test.com
    http:
      paths:
      - backend:
          serviceName: test
          servicePort: 80
        path: /
