在Docker下载Nginx镜像

docker pull nginx
docker images

创建挂载目录

mkdir -p /data/nginx/{conf,conf.d,html,logs}


编写nginx,conf配置文件，并放在文件夹中

#这块是我要负载均衡的三个es的node
upstream pic{
            server 114.115.249.25:9200 weight=5;
            server 114.115.249.25:9201 weight=5;
            server 114.115.249.25:9202 weight=5;
}

}

启动容器
这边需要开启82端口，宿主机的82对应容器内部的80，-v是挂载宿主机的一个目录

docker run --name mynginx -d -p 82:80  -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf  -v /data/nginx/logs:/var/log/nginx -d docker.io/nginx

我部署了三个es的node，坐了下负载均衡
