docker_file编写-07

一、docker_file文件编写

参考官网：https://hub.docker.com/_/centos/

docker_file是用来全自动的构建文件。

 

1.2、download centos6.6的dockerfile

#查看是否有wget
[root@docker-node1 ~]# rpm -qa wget 
wget-1.14-15.el7_4.1.x86_64

#download centos6.6 docker_file
[root@docker-node1 ~]# wget https://github.com/CentOS/sig-cloud-instance-images/blob/8911843d9a6cc71aadd81e491f94618aded94f30/docker/Dockerfile

#创建并移到docker文件夹中
mkdir docker
mv Dockerfile docker
cd docker

#清空文件
echo > Dockerfile　

1.3、编写Dockerfile

vim Dockerfile

#build

 #查看所有images

#运行nginx

 

 #

#进入容器

#curl

1.4、官方示例
