I understand I can change the docker image for a component in the pipeline, but for the

it isn’t possible.

you can always to Task.current_task.connect() from the pipeline function itself, to connect more configuration arguments you basically add via the function itself, all the pipeline logic function arguments become pipeline arguments, it's kind of neat 🙂 regrading docker, the idea is that you use a very basic python docker (the default for services) queue for all the pipeline logic, that said, inside the pipeline function you can call Task.current_task.set_base_docker() and set the base docker to be used. The only caveat is that you first have to run it locally.
It might be a good idea to add docker option to the decorator itself regardless, like we have in the component, wdty?
