docker 制作docker镜像

#宿主机：启动一个纯净centos:7的容器，安装nginx 并且进入容器
docker run -it -p 80:80 centos:7 /bin/bash

#容器：配置base源 epel源 hosts本地解析 
echo "192.168.13.251  mirrors.aliyun.com" >>/etc/hosts
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

#在容器里安装nginx
yum install nginx -y

#容器：编辑首页文件
rm -rf index.html
echo 'wyd' > /usr/share/nginx/html/index.html

#宿主机：制作镜像
docker container commit 6e1ab2a7291e centos7_nginx:v1

#宿主机：启动容器
docker run -d -it -p 80:80 centos7_nginx:v1 nginx -g 'daemon off;'

制作一个基于centos7系统的kod网盘的镜像

#宿主机：启动一个纯净centos:7的容器，安装nginx 并且进入容器
docker run -it -p 80:80 centos:7 /bin/bash

#容器：配置base源 epel源 hosts本地解析 
echo "192.168.13.251  mirrors.aliyun.com" >>/etc/hosts
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

#容器：下载nginx+php服务 修改php,nginx配置文件 启动服务
yum -y install nginx php-fpm php-gd php-mbstring
vi /etc/php-fpm.d/www.conf 
user = nginx
group = nginx

/usr/sbin/php-fpm --daemonize #启动php服务

vi /etc/nginx/nginx.conf
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
