docker nginx 负载均衡

index1.html

<html>
<head>
	<title>lb-test</title>
</head>
<body>
	<p>11111111</p>
</body>
</html>

同理建立index2.html，内容为222222

nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    upstream yourwebname {
        # yourhostip:port;
        server 192.168.43.130:8000 weight=2;
        server 192.168.43.130:8001 weight=2;  
    }

    server {
        listen 80;

        location / {
            proxy_pass http://yourwebname;
        }
    }
}

启动镜像

run -p 80:80 -v /home/nginx.conf:/etc/nginx/nginx.conf --name master nginx
docker run -p 8000:80 --name myweb1 -v /home/index1.html:/usr/share/nginx/html/index.html -d nginx
docker run -p 8001:80 --name myweb2 -v /home/index2.html:/usr/share/nginx/html/index.html -d nginx

浏览器访问192.168.43.130，持续刷新即可看到1111111，22222222内容交替显示
