Hello,

I'm a embedded software engineer but a beginner of the Alpine Linux.

I want to create the same  tarball for Raspberry Pi from source codes
as alpine-rpi-3.14.1-aarch64.tar.gz which is provided on https://www.alpinelinux.org/downloads/ 
for my understanding

Could you tell me the best way to create it ?


I have already succeeded to compile each APKs for aarch64 
by using https://github.com/alpinelinux/docker-abuild and x86_64 based Linux PC.
But I could not find any information on wiki to create release tarball on  cross environment.

Best regards,
  T.Komagata

I do this by creating an arm chroot environment with alpine-chroot-install [1],
cloning the aports tree, and then using scripts/mkimage.sh [2] in the aports tree
to generate the tarball. The profile name you are looking for will be rpi
(which is defined in scripts/mkimg.arm.sh). Take a look at the mkimage.sh source
for usage.
