We already have Docker containers, which you can fetch from the
Dockerhub repository operated by Sysadmin:
https://hub.docker.com/u/kdeorg

The Dockerfiles and other resources for these images are stored in the
sysadmin/ci-tooling repository, under system-images/

While i'm not familiar with the entire build process, the steps run by
the Binary Factory (which in turns produces the APK files
redistributed through the F-Droid repository) are documented in the
Jenkins pipeline for those jobs, which can be found in
sysadmin/binary-factory-tooling, in the android/ folder.

The variables mentioned in that pipeline can be found in the
current-jobs.json file in the same folder.

For more detail i'd suggest mailing the kde-android at kde.org mailing list (CC'ed)
