Here is a first suggestion for a templating mechanism to generate images files. It introduces a manifest/version file to manage all versions/distros/versions/hashes. It's not defined how the manifest should be designed, it's a discussion base.
I used a built-in python Template system to use a variable with
%delimiter in the Dockerfile to dynamically change it with python variables, it enables regular Dockerfile variable with$and template variable with%.About alpine & potentially other bases, a lot may evolve, I tried to figure out some components which may change to update it when things evolve.
load_templatemay select different base according to a variant/distro for example, variables for templates are set in 3 lines and withrelease_files, which may be updated depending on manifest evolution.I followed the behavior of openjdk apply-templates.sh which delete and recreate all files. Their template script vary, the current script is pretty dumb and do not provide option, behavior to discuss too.
