Docker使用数据卷提供配置文件(提供不同的配置文件来访问不同web的页面）

[root@docker ~]# ls

[root@docker ~]# mkdir -p /var/www/html
[root@docker ~]# cp -r jiaoben1765/* /var/www/html/
[root@docker ~]# ls /var/www/html/
css  img  index.html  js

[root@docker nginx]# cd

我们通过IP和添加映射的到本机的端口进行访问测试

在本机修改和容器映射的网站文件
[root@docker ~]# cd /var/www/html/
[root@docker html]# ls
css  img  index.html  js
[root@docker html]# mv index.html a.html
[root@docker html]# vi index.html
[root@docker html]# cat index.html 
This is test page!!!
[root@docker html]# 

再次测试访问

[root@docker html]# mkdir test
[root@docker html]# ls
a.html  css  img  index.html  js  test
[root@docker html]# mv index.html test/
[root@docker html]# mv a.html index.html
[root@docker html]# ls
css  img  index.html  js  test
[root@docker html]# 

[root@docker ~]# cd /config/
[root@docker config]# vi nginx.conf
......
  # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       8080;
        server_name  test.example.com;

        location / {
            root         /usr/share/nginx/html/test;
            index        index.html;
        }
}


    server {
        listen       80;
        server_name  game.example.com;

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

        location / {
            root      /usr/share/nginx/html;
            index     index.html;
        }
......

//映射容器的8080到本机80，容器80到本机80端口，这杨就能通过不同的端口访问不同的网站服务
[root@docker ~]# docker run -itd -p 80:80 -p8080:8080 --name web01 --volumes-from nginx_config nginx
