podman用脚本和dockerfile做apache编译安装镜像（alpine版）

alpine系统是什么

Alpine Linux 是一个基于 musl libc 和 busybox 的面向安全的轻量级 Linux 发行版。

alpine系统的特点

小巧：基于Musl libc和busybox，和busybox一样小巧，最小的Docker镜像只有5MB；

安全：面向安全的轻量发行版；

简单：提供APK包管理工具，软件的搜索、安装、删除、升级都非常方便。

适合容器使用：由于小巧、功能完备，非常适合作为容器的基础镜像。

alpine镜像下载

alpine官网

alpine国内源
清华大学：https://mirror.tuna.tsinghua.edu.cn/alpine/
阿里云：https://mirrors.aliyun.com/alpine/
网易：http://mirrors.163.com/

更换apk源

sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories
alpine基础命令
apk update //更新最新镜像源列表

apk search //查找所以可用软件包

apk search -v //查找所以可用软件包及其描述内容

apk search -v ‘acf*’ //通过软件包名称查找软件包

apk search -v -d ‘docker’ //通过描述文件查找特定的软件包

apk add openssh //安装一个软件

apk add openssh openntp vim //安装多个软件

apk add --no-cache mysql-client //不使用本地镜像源缓存，相当于先执行update，再执行add

apk info //列出所有已安装的软件包

apk info -a zlib //显示完整的软件包信息

apk info --who-owns /sbin/lbu //显示指定文件属于的包

apk upgrade //升级所有软件

apk upgrade openssh //升级指定软件

apk upgrade openssh openntp vim //升级多个软件

apk add --upgrade busybox //指定升级部分软件包

apk del openssh //删除一个软件

服务管理

alpine没有使用fedora的systemctl来进行服务管理，使用的是RC系列命令：

rc-update //主要用于不同运行级增加或者删除服务

rc-status //主要用于运行级的状态管理

rc-service //主用于管理服务的状态

rc-status -a //列出系统所有服务
关闭系统
reboot //重启系统

poweroff //关机
dockerfile创建apache镜像

创建好目录结构

创建好一个目录存放包和dockerfile

[root@localhost ~]# mkdir httpd
[root@localhost ~]# cd httpd
[root@localhost httpd]# mkdir files
[root@localhost httpd]# touch Dockerfile
[root@localhost httpd]# cd
[root@localhost ~]# mv *.tar.gz httpd/files/
编写一个entrypoint.sh的脚本
[root@localhost httpd]# cd files/
[root@localhost files]# vim entrypoint.sh 
#!/bin/bash

sed -i '/^ServerName/s/#//g' /usr/local/apache/conf/httpd/conf

exec "$@"
[root@localhost files]# chmod +x entrypoint.sh

编写dockerfile

[root@localhost ~]# cd httpd/
[root@localhost httpd]# vim Dockerfile
[root@localhost httpd]# cat Dockerfile
FROM alpine

LABEL MANTAINER "SHU 2228706561@qq.com"
