dockerfile构建与部署nginx
1. 创建dockerfile存放目录
1.1 创建目录
[root@docker ~]# mkdir -p /dockerfile
[root@docker ~]# cd /dockerfile/
[root@docker dockerfile]# mkdir -p nginx
[root@docker dockerfile]# cd nginx/
2. 创建nginx dockerfile配置文件
2.1 创建文件
[root@docker nginx]# touch Dockerfile
2.2 编写文件
[root@docker nginx]# vim Dockerfile
[root@docker nginx]# cat Dockerfile
#this docker file
#VERSION 1

CMD ["-g","daemon off;"]
3. 构建nginx配置文件
[root@docker nginx]# docker build -t nginx:v1 .
