一、拉取镜像

docker pull nginx
docker images

二、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

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

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

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  182.254.161.54;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        proxy_pass http://pic; 
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

    upstream pic{
                server 182.254.161.54:8088 weight=5;
                server 182.254.161.54:8089 weight=5;
    }

}

三、启动容器

 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

• 查看启动的容器

docker ps -a

四、Nginx热更新

• 对 docker 容器里的 nginx 进行热更新

docker exec -i [nginx容器名/id] nginx -s reload
