alpine, is the smallest Linux distribution a weight of only 5 MB. It also has basic linux tool and a good package manager APK. APK very stable, a significant number of packages. Due to small size, very popular in the container, but also use a lot of the pit, most probably our ignorance of it.
Pit 1: Download Slow

echo "https://mirror.tuna.tsinghua.edu.cn/alpine/v3.4/main" > /etc/apk/repositories \
&& echo "https://mirror.tuna.tsinghua.edu.cn/alpine/v3.4/community" >> /etc/apk/repositories \
&& echo "https://mirror.tuna.tsinghua.edu.cn/alpine/edge/testing" >> /etc/apk/repositories

I can install in the virtual package gcc and other necessary packages, and you can delete all the dependencies, and delete the virtual package name. The following is an example of usage
the Add - Virtual mypacks gcc vim APK
APK del mypacks
use the first command to install all of the 18 packages will be deleted the next command.
Note: The same parameters for all installation packages before -t will cover all best not to use -t dynamic link library, or to ensure that this parameter is not repeated.
