kubesphere 中 Ingress 域名方式导致413 Request Entity Too Large

k8s集群中，将图片或是文件上传到文件服务器上，请求body的长度大于1M是就会报错
413 Request Entity Too Large

解决方案

一、在web的nginx.conf中添加

client_body_buffer_size 50m;
client_max_body_size 100m;

二、在ingress中添加 

annotations:
   nginx.ingress.kubernetes.io/proxy-body-size:"50m"

在ingress的annotations下添加相关的参数

kind: Ingress
apiVersion: extensions/v1beta1
metadata:
  name: lys-router
  namespace: lys-ns
  annotations:
    kubesphere.io/alias-name: lys-router
    kubesphere.io/creator: admin
    kubesphere.io/description: 控制台路由
    nginx.ingress.kubernetes.io/proxy-body-size: 102400m
    nginx.ingress.kubernetes.io/proxy-connect-timeout: '300'
    nginx.ingress.kubernetes.io/proxy-read-timeout: '300'
    nginx.ingress.kubernetes.io/proxy-send-timeout: '300'
spec:
  tls:
    - hosts:
        - nginx.lys.com
      secretName: my-crt-secret
  rules:
    - host: cv.sugon.tech
      http:
        paths:
          - path: /
            pathType: ImplementationSpecific
            backend:
              serviceName: web-main
              servicePort: 80
