Can the image-automation-controller preserve blank lines in yaml files?

[jammy-d]

When the image-automation-controller updates an image on a yaml file, it seems to have the default behaviour to remove any blank lines in the file.

In most manifests this may be fine, but the image-automation-controller is able to update non-manifest yaml files, e.g. .gitlab-ci.yml, docker-compose.yml, etc. For these files it is fairly common to have blank lines between structured blocks.

Is it currently possible, or would it be possible to have the image-automation-controller preserve these blank lines (and any general structure in the YAML file), so that it effectively only edits the lines that are intended to be edited?

We're pretty much depending on the upstream kyaml lib for this functionality and that doesn't have a way to preserve blank lines. I'd be more than happy if you would be able to raise a ticket with the kustomize project in this matter.

Thanks @makkes for the reply. I would like to raise the ticket on kustomize project. Is there any additional info, I can add to the ticket for when the image-automation-controller applies its changes?

There's #117 with some rabbit holes into kustomize issues, but it seems this particular issue was never explicitly raised upstream.

That said, I agree it's a real issue with my use-case too, doing updates to values.yaml files that rely on comments and blank lines for legibility.
