一 目录规划
1.1 创建dockerfile目录
root@k8s-harbor-01:~# mkdir /data/dockerfile/{web/{nginx,tomcat,jdk},system/{centos,ubuntu,alpine}} -p
1.2 查看创建的结果
oot@k8s-harbor-01:~# tree /data/dockerfile/
/data/dockerfile/
├── system
│ ├── alpine
│ ├── centos
│ └── ubuntu
└── web
├── jdk
├── nginx
└── tomcat
8 directories, 0 files
1.3 当前系统版本
root@k8s-harbor-01:~# cat /etc/issue
Ubuntu 20.04.3 LTS \n \l
二 制作centos base image
2.1 pull centos image
root@k8s-harbor-01:~# docker pull centos:7.9.2009
2.2 编写Dockerfile
root@k8s-harbor-01:/data/dockerfile/system/centos# cat Dockerfile
FROM centos:7.9.2009
RUN yum -y install wget \
&& rm -rf /etc/yum.repos.d/* \
&& wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/Centos-7.repo \
&& wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-7.repo \
&& yum clean all \
&& rm -rf /etc/localtime \
&& ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
2.3 编写构建镜像脚本
root@k8s-harbor-01:/data/dockerfile/system/centos# cat build-command.sh
#!/bin/bash
docker build -t 192.168.174.120/baseimages/centos-base:7.9.2009 .
#docker push 192.168.174.120/baseimages/centos-base:7.9.2009
2.4 构建镜像
root@k8s-harbor-01:/data/dockerfile/system/centos# bash build-command.sh
2.5 验证镜像
root@k8s-harbor-01:/data/dockerfile/system/centos# docker run -it --rm 192.168.174.120/baseimages/centos-base:7.9.2009 /bin/bash
