# Docker image when built on the official Docker infrastructure.

|
# They require us to verify the source integrity in some way while making sure that this is a
|
||
|
|
# reproducible build.
|
||
|
|
# See https://github.com/docker-library/official-images#image-build
|
||
|
|
# In order to achieve this, we externally host the rootfs archives and their checksums and then
|
||
|
|
# just download and verify it in the first stage of this Dockerfile.
|
||
|
|
# The second stage is for actually configuring the system a little bit.
|
||
|
|
# Some templating is done in order to allow us to easily build different configurations and to
|
||
|
|
# allow us to automate the release process.
|
||
|
|
|
||
|
|
# Note: Only official DockerHub images are allowed, see https://gitlab.archlinux.org/archlinux/archlinux-docker/-/commit/daa67d18579024947d69a45e6d028c5adb1c8c23
|
||
|
|
# While we could use archlinux:base it could also break our build process, so we avoid dog fooding here
