使用示例

下面列举常用命令：

apk update

update：从远程镜像源中更新本地镜像源索引。

update命令会从各个镜像源列表下载APKINDEX.tar.gz并存储到本地缓存，一般在/var/cache/apk/(Alpine在该目录下)、/var/lib/apk/ 、/etc/apk/cache/下。

apk add

add：安装PACKAGES并自动解决依赖关系。

add命令从仓库中安装最新软件包，并自动安装必须的依赖包，也可以从第三方仓库添加软件包。

$ 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

安装指定版本软件包

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

apk del

del：卸载并删除PACKAGES

apk del openssh openntp vim

apk upgrade

upgrade：升级当前已安装的软件包。

upgrade命令升级系统已安装的所有软件包（一般包括内核），当然也可指定仅升级部分软件包（通过-u或–upgrade选择指定）。

$ apk update #更新最新本地镜像源
$ apk upgrade #升级软件
$ apk add --upgrade busybox #指定升级部分软件包

apk search

search：搜索软件包。

search命令搜索可用软件包，-v 参数输出描述内容，支出通配符，-d 或 –description 参数指定通过软件包描述查询。
