我的环境

k8s部署环境: 本地虚拟机搭建的集群,1 master + 2 nodes
k8s版本: v1.14.0,昨天被我升级为:v1.14.0
k8scni插件: weave或flannel
LoadBalancer Provider: metallb
Ingress: k8s 维护的ingress-nginx 和nginx社区维护的ingress-nginx都尝试过

存在问题

wssocket通过ingress路由进行握手。
wssocket无法通过ingress路由进行握手。

如果通过service暴露出的ip和端口进行握手是没有问题的,如下下图:

如果将service type的设置的类型设置为:NodePort，通过映射的ip和端口就无法进行握手,如下图:

通过 nginx-ingress 进行握手也是不行的,如下图:

nginx的配置文件如下:

# configuration for default/wsservice-ingress

upstream default-wsservice-ingress-wsservice.dev.ifoc.com-wsservice-96 {
        random two least_conn;

        server 10.46.0.5:96 max_fails=1 fail_timeout=10s;

}


server {


        listen 80;






        server_tokens on;

        server_name wsservice.dev.ifoc.com;






        location / {


                proxy_http_version 1.1;

                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection $connection_upgrade;

                proxy_connect_timeout 60s;
                proxy_read_timeout 60s;
                client_max_body_size 1m;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Host $host;
                proxy_set_header X-Forwarded-Port $server_port;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_buffering on;

                proxy_pass http://default-wsservice-ingress-wsservice.dev.ifoc.com-wsservice-96;


        }


}

请问老师，这个可能是什么原因造成的，怎么处理?
