Terragrunt Manager not yet able to fetch GitLab release notes

[lstoeferle]

Hi everyone,
we're hosting a bunch of terraform modules in a self-hosted GitLab instance, that are used/included in several other terraform projects. Renovate can find those dependencies and is able to open a PR in case we published a new tf-module version via GitLab releases.

Unfortunately the PRs do not include any changelog, since the terragrunt manager currently only supports git-tags, github-tags and terraform-module datasources, which are not able to fetch changelogs from out GitLab Releases.

Is it possible to extend the terragrunt manager to be able to fetch the changelogs?

I'm happy to work on a PR, but first I want to hear your opinion and maybe you already know how to start implementing such a feature. I personally thought about adding support for the gitlab-releases datasource.

Kind regards,
Lukas

PS: using self-hosted Renovate on GitLab

The manager itself doesn't need to support changelogs explicitly. What's needed is that results are returned from a datasource which itself supports the sourceUrl field. If the gitlab package are being looked up via git-tags currently then it may be enough that they get looked up via gitlab-tags instead with a little rework in the manager to identify dependencies hosted on gitlab similar to how it does for github

Hi @rarkins,
I've opened a PR here #27903.

Hi there,

Please do not unnecessarily @ mention maintainers like @rarkins or @viceice. Doing so causes annoying mobile notifications and makes it harder to maintain this repository.

For example, never @ mention a maintainer when you are creating a discussion if your desire is to get attention. This is rude behavior, just like shouting out your coffee order in a Starbucks before it's your turn.

It's OK to comment in an issue or discussion after multiple days or weeks. But please, still don't @ mention people. The maintainers try to answer most discussions, but they can't answer all discussions. If you're still not getting an answer, take a look at the information you've given us and see if you can improve it.

Thanks, the Renovate team
