1、创建上下文环境并创建首页文件(压缩)

  1. [root@localhost ~]# mkdir nginx && cd nginx
  2. [root@localhost nginx]# echo "hello docker" > index.html

2、编写Dockerfile

  1. [root@localhost nginx]# cat Dockerfile 
  2. ARG version=7
  3. FROM centos:${version}
  4. MAINTAINER HWJ
  5. RUN mkdir /hwjvol
  6. VOLUME ["vdata1","hwjvol"]
  7. LABEL version="12" author=hwj description="This is hwj's nginx"
  8. RUN yum install -y wget 
  9. RUN wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
  10. RUN yum install -y nginx
  11. RUN echo "daemon off;" >> /etc/nginx/nginx.conf
  12. ADD index.html /usr/share/nginx/html/index.html
  13. EXPOSE 80 443 
  14. CMD ["/usr/sbin/nginx"]

3、构建镜像

  1. [root@localhost nginx]# docker build -t hwj_ng:12 -f /root/nginx/Dockerfile .
  1. Sending build context to Docker daemon  4.096kB
  2. Step 1/13 : ARG version=7
