svc 实现负载均衡实现基于80端访问所有的游戏 案例 

将"游戏镜像部署到K8S集群"，使用任意3个游戏镜像即可，要求使用不同的svc暴露服务，并使用负载均衡实现基于80端访问所有的游戏；

nginx  配置：

[root@web03 /etc/nginx/conf.d]#cat lbporxy.conf

server {
        listen 80;
        server_name game01.baimei.com;
        
        location / {
                proxy_pass http://10.0.0.233:40001;
                include proxy_params;
        }
}

server {
        listen 80;
        server_name game02.baimei.com;
        
        location / {
                proxy_pass http://10.0.0.233:40002;
                include proxy_params;
        }
}



server {
        listen 80;
        server_name game03.baimei.com;
        
        location / {
                proxy_pass http://10.0.0.233:40003;
                include proxy_params;
        }
}

[root@web03 /etc/nginx]#cat proxy_params

proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_connect_timeout 30;
proxy_send_timeout 60;
proxy_read_timeout 60;

proxy_buffering on;
proxy_buffer_size 32k;
proxy_buffers 4 128k;
