What is your question?

we have a file in our repository - called image.lst that contains a list of docker images that are used in other parts of our code base. (this is used to pull an offline copy of the images for an air-gapped install, but I don't think that is relevant here)

this file has one docker image/tag/digest per line e.g. looks a bit like this (the actual file is a bit longer)

busybox:1.36.1@sha256:6d9ac9237a84afe1516540f40a0fafdc86859b2141954b4d643af7066d598b74

renovate is happily creating PR's to update our kubernetes manifests (yaml files) with new images, is there any way I can tell renovate about this file and get it to update the relevant line here at the same time?

I would be open to minor changes to the file format / name as well if that was needed to get this working, as long as I can still process the list of images in a script afterwards.

Many thanks

Yes, use a custom (regex) manager: https://docs.renovatebot.com/modules/manager/regex/
