一般一个软件官方用什么os作容器就用他,不一定是alpine才是最好的 例如 mysql  python就可能不是

=软件包管理工具apk的基本使用=
<pre>
可以方便地安装、删除、更新软件。

#查询openssh相关的软件包

apk search  openssh   

#安装一个软件包

apk add  xxx   

#删除已安装的xxx软件包

apk del  xxx   

#获取更多apk包管理的命令参数

apk --help   

 

#比如安装常用的网络相关工具：

#更新软件包索引文件

apk update    

#用于文本方式查看网页，用于测试http协议

apk add curl  

#提供了查看网络连接的协议端口的命令ss，可以替代netstat命令

apk add iproute2  

#drill 命令可以替代dig和nslookup DNS查询命令

apk add drill

==alpine镜像crontab无法运行问题 ==
<pre>
alpine镜像 普通用户 crontab无法运行问题

crond 服务用 root用户启动   or on ci  docker-compose exec -u  root  -T php-worker  sh -c "crond"

如果用官方提供alpine镜像是不自动启动crond的，得手动起
每个用户有单独的文件在/etc/crontabs文件夹
可以用supervisor启动crond，但要用root用户去启动crond，运行其他用户的定时任务

cron itself should run as root, regardless of which user you want to use to run the jobs.

This will install a crontab for user robuser. When cron executes jobs from this particular crontab, it will automatically switch users to robuser. However, cron can’t switch users like that if it’s not running as root, which is why you need to be running cron as root.

 crontab  -l 
crontab: must be suid to work properly

apk add --update busybox-suid

=问题=
Alpine Linux使用了musl，可能和其他Linux发行版使用的glibc实现会有所不同。在容器化中最可能遇到的是DNS问题，即musl实现的DNS服务不会使用resolv.conf文件中的search和domain两个配置，这对于一些通过DNS来进行服务发现的框架可能会遇到问题
