Alpine Linux是一個面向安全應用的輕量級Linux發行版。它采用了musl libc和busybox以減小系統的體積和運行時資源消耗，同時還提供了自己的包管理工具apk。
官方幫助文檔

alpine 提供了非常好用的apk軟件包管理工具，通過apk –help命令查看完整的包管理命令。

使用示例

下面列舉常用命令：

apk update

update：從遠程鏡像源中更新本地鏡像源索引。

update命令會從各個鏡像源列表下載APKINDEX.tar.gz并存儲到本地緩存，一般在/var/cache/apk/(Alpine在該目錄下)、/var/lib/apk/ 、/etc/apk/cache/下。

apk add

add：安裝PACKAGES并自動解決依賴關系。

add命令從倉庫中安裝最新軟件包，并自動安裝必須的依賴包，也可以從第三方倉庫添加軟件包。

$ apk add openssh openntp vim
$ apk add --no-cache mysql-client
$ apk add docker --update-cache --repository http://mirrors.ustc.edu.cn/alpine/v3.4/main/ --allow-untrusted

安裝指定版本軟件包

$ apk add asterisk=1.6.0.21-r0
$ apk add ‘asterisk<1.6.1’
$ apk add 'asterisk>1.6.1

apk del

del：卸載并刪除PACKAGES

apk del openssh openntp vim

apk upgrade

upgrade：升級當前已安裝的軟件包。

upgrade命令升級系統已安裝的所有軟件包（一般包括內核），當然也可指定僅升級部分軟件包（通過-u或–upgrade選擇指定）。

$ apk update #更新最新本地鏡像源
$ apk upgrade #升級軟件
$ apk add --upgrade busybox #指定升級部分軟件包

apk search

search：搜索軟件包。

search命令搜索可用軟件包，-v 參數輸出描述內容，支出通配符，-d 或 –description 參數指定通過軟件包描述查詢。

$ apk search #查找所有可用軟件包
$ apk search -v #查找所有可用軟件包及其描述內容
$ apk search -v ‘acf*’ #通過軟件包名稱查找軟件包
$ apk search -v -d ‘docker’ #通過描述文件查找特定的軟件包

apk info

info：列出PACKAGES或鏡像源的詳細信息。

info命令用于顯示軟件包的信息。

$ apk info #列出所有已安裝的軟件包
$ apk info -a zlib #顯示完整的軟件包信息
$ apk info --who-owns /sbin/lbu #顯示指定文件屬于的包
