虚拟机 server1
- 使用
xftp或dnf -y install lrzsz，将宿主机中的Centos-7.repo、epel-7.repo文件拖至该虚拟机中
[root@localhost ~]# ls
anaconda-ks.cfg Centos-7.repo epel-7.repo
- 部署 Dockerfile
[root@localhost ~]# vim Dockerfile
FROM centos:7 //基于基础镜像centos:7
MAINTAINER [email protected] //维护者信息
ADD Centos-7.repo /etc/yum.repos.d/ //添加Centos-7仓库
ADD epel-7.repo /etc/yum.repos.d/ //添加epel-7仓库
RUN yum -y install nginx //安装nginx软件包
EXPOSE 80 //暴露指定端口80
CMD ["/usr/sbin/nginx","-g","daemon off;"]
- 构建镜像，镜像名称为 nginx:v1

虚拟机 server1
使用xftp或dnf -y install lrzsz，将宿主机中的Centos-7.repo、epel-7.repo、kodexplorer4.40.zip、nginx.txt文件拖至该虚拟机中
- 创建 /opt/dockerfile/kod 目录，将所需的软件包和文件放置该目录下
[root@localhost ~]# ls
anaconda-ks.cfg Centos-7.repo epel-7.repo kodexplorer4.40.zip nginx.txt
[root@localhost ~]# mkdir -p /opt/dockerfile/kod/
[root@localhost ~]# cd /opt/dockerfile/kod/
[root@localhost kod]# cp /root/* /opt/dockerfile/kod
[root@localhost kod]# rm -f anaconda-ks.cfg
[root@localhost kod]# mv nginx.txt nginx.conf
