应用出现上传文件大小限制，报错413 Request Entity Too Large

经过检查发现是k8s nginx ingress 里面默认参数太小，需要修改，在ingress里面client_max_body_size不是配置成全局参数的，而是配置在server里面，修改方法如下

在ingress配置hosts的位置配置，在 annotations: 下面增加nginx.ingress.kubernetes.io/proxy-body-size: "100m"

  apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    annotations:
      kubernetes.io/ingress.class: nginx
      nginx.ingress.kubernetes.io/proxy-body-size: "100m"
    name: qa-zhy

            - backend:
                serviceName: qa-zhy
