配置应用之后, nginx没有写入响应的配置, 是什么原因呢?

[root@k-master ~]# cat nginx-config.yaml 
kind: ConfigMap
apiVersion: v1
metadata:
  name: nginx-configuration
  namespace: ingress-nginx
  labels:
    app: ingress-nginx
data:
  proxy-body-size: "64m"
  proxy-read-timeout: "180"
  proxy-send-timeout: "180"
[root@k-master ~]# kubectl apply -f nginx-config.yaml
configmap/nginx-configuration configured
[root@k-master ~]# kubectl exec -n ingress-nginx -it ingress-nginx-controller-xhjh2 -- cat /etc/nginx/nginx.conf | grep 64
