##  LabInstance Alpine 3.15


You have to have a base image on which you will install all of your library and code to create your own custom image. you can use any base image like debian, centos,ubuntu.But you will be certainly biased to any image which is small in size and which has all the repo link. And there come alpine.

From alpine description 

Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications.


### *Everything works fine with docker => 20.10.11.*



> 
> For comparison, here’s how Alpine compares to other popular distributions of Linux:
> 
> DISTRIBUTION	VERSION	SIZE
> 
> Debian	Jessie	123MB
> 
> CentOS	7	193MB
> 
> Fedora	25	231MB
> 
> Ubuntu	16.04	118MB
> 
> Alpine	3.*	4.98MB
> 

Difference in size. Alpine is about 30x smaller than Debian.


 Is there a best practice on setting up glibc on docker alpine linux base image?
