Docker Chenyufeng/nginx-centos mirroring to achieve load balancing

In a previous blog we achieved load balancing using Docker's official Nginx mirroring, which is not easy to use, and uses my own mirrors: Chenyufeng/nginx-centos to achieve load balancing. It will be more convenient to use Chenyufeng/nginx-centos mirroring to match the configuration of Nginx on Linux.
The/usr/local/nginx/conf/nginx.conf configuration is as follows:
#user nobody; Worker_processes 1;
#error_log Logs/error.log; #error_log Logs/error.log Notice; #error_log Logs/error.log Info;
#pid Logs/nginx.pid;

Events {worker_connections 1024;}

HTTP {include mime.types; Default_type Application/octet-stream;
#log_format Main ' $remote _addr-$remote _user [$time _local] "$request" ' # ' $status $body _bytes_sen T "$http _referer" "$http _user_agent" "$http _x_forwarded_for";
#access_log Logs/access.log Main;
Sendfile on; #tcp_nopush on;
#keepalive_timeout 0; Keepalive_timeout 65;
#gzip on;
# key steps Upstream backend {server 192.168.0.101:8080;    Server 192.168.0.101:8081; }

} daemon off;


Action Step: Start container
Docker run--name web-ng-d-P 22:22-p 80:80-p 443:443

Enter container Modify Configuration profile location:/usr/local/nginx/conf/nginx.conf
Docker exec-it Web-ng/bin/bash
Restart reboot after modifying configuration complete
Docker Restart Web-ng

Load balancing can be achieved directly in the browser http://localhost/col/docs/index.html
Any invocation of an interface is load balanced.
