5-Docker实例-centos-nginx(3)

基于上次制作的centos-systemctl:1.0镜像，在其上安装nginx rpm，并构建nginx镜像。

1.制作nginx Dockerfile，并保存

命令：

vim Dockerfile

FROM centos-systemctl:1.0
MAINTAINER ztj

COPY nginx.repo /etc/yum.repos.d/
COPY epel.repo /etc/yum.repos.d/
COPY epel-testing.repo /etc/yum.repos.d/

RUN yum install nginx net-tools -y

EXPOSE 80

2.基于Dockerfile创建镜像

命令：

docker build -f Dockerfile -t centos-nginx:1.0 .

[root@centos79 ~]# docker build -f Dockerfile -t centos-nginx:1.0 .
