@Matthias Roels very much sympathise with your pain here! This discussion is very relevant: https://github.com/kedro-org/kedro/discussions/1436. The way to do this now is through the hook

after_context_created

that makes available

context.config_loader

. You can pass this as a global variable to your

register_pipelines

function and do

config_loader.get("pipeline")

(or whatever) there. This still feels very hacky to me and I would like to have a better way to do it, but unfortunately since per-environment pipeline.yml files isn't really the "kedro way" it is awkward to support. IMO we should make it much easier for people to use a plugin that enables this functionality
