实战案例:Dockerfile 直接制作nginx镜像
在Dockerfile目录下准备编译安装的相关文件
[root@ubuntu1804 ~]#mkdir /data/dockerfile/web/nginx/1.16.1
[root@ubuntu1804 ~]#cd /data/dockerfile/web/nginx/1.16.1
[root@ubuntu1804 1.16.1]#vim nginx.conf
user  nginx;
worker_processes  1;
#daemon off;
[root@ubuntu1804 1.16.1]#wget http://nginx.org/download/nginx-1.16.1.tar.gz
编写Dockerfile文件
[root@ubuntu1804 1.16.1]#pwd
/data/dockerfile/web/nginx/1.16.1
[root@ubuntu1804 1.16.1]#vim Dockerfile
[root@ubuntu1804 1.16.1]#cat Dockerfile
