外网访问进来再到内网ingress

1、阿里云解析

demob.t s-it.cn ---> 58.56.21.14（公网地址）

demodp.ts-it.cn ---> 58.56.21.14（公网地址）

2、网关做端口映射

（网关上做端口映射）

​ 58.56.21.14:8181 ---> 192.168.11.202:8181

​ 58.56.21.14:8182 ---> 192.168.11.202:8182

3、内网新起一个nginx

3.1、k8s上起一个nginx负载

配置文件如下：

user nginx;
worker_processes auto;

error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
}

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
keepalive_timeout 65;

#client_max_body_size 1024m;

server {
listen 8181 default_server;
server_name 192.168.11.200;

location / {
proxy_pass http://demob.ts-it.cn;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Scheme $scheme;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";

}
}

server {
listen 8182 default_server;
server_name 192.168.11.200;

location / {
proxy_pass http://demodp.ts-it.cn;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Scheme $scheme;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";

}
}

include /etc/nginx/conf.d/*.conf;
}

然后添加端口映射，HostPort 和 NodePort均可

3.2、宿主机上直接起动nginx服务

将上述配置文件直接覆盖nginx.conf即可!
