provide Docker image tags for minor and major releases (coarser matching)

[das-g]

Additionally to the tags with the full patch version x.y.z, provide tags that allow to be on the latest release of a certain minor version x.y and tags that allow to be on the latest release of a certain major version x.

So
Tag 1.1 should point to the same image as the latest 1.1.* tag (currently 1.1.0, later maybe 1.1.15, but never 1.2.0).
Tag 1 should point to the same image as the latest 1.*.* tag (currently 1.1.0, later maybe 1.5.42, but never 2.0.0).

Off course this is only really useful if this project uses semantic versioning. But although I didn't see it declared explicitly, I assume that's the case, isn't it?

Hello @das-g , thanks for opening this issue! The use case is described clearly, and it is a legit request.
We'll see how to implement this behavior, but if you feel ready, do not hesitate to open a PR with a proposal (even as a "draft"), as any help is welcome.

Thanks!

I think this is best done through the autobuild configuration on dockerhub.

Type	Name	Dockerfile Location	Docker Tag Name
Branch	master	/	latest
Tag	/^v([0-9]+)\.([0-9]+)\.([0-9]+)$/	/	{\1}
Tag	/^v([0-9]+)\.([0-9]+)\.([0-9]+)$/	/	{\1}.{\2}
Tag	/^v([0-9]+)\.([0-9]+)\.([0-9]+)$/	/	{\1}.{\2}.{\3}

That would have to be done by someone with configuration access to https://github.com/asciidoctor/docker-asciidoctor.

Whether there's any way to accomplish the same through a PR (i.e., by changing the content of files in this repo), I don't know.

Thanks a lot @das-g for these insights.

The release 1.2.0 had been published with this new tags, and the previous tagged version are currently being rebuilt: https://hub.docker.com/repository/docker/asciidoctor/docker-asciidoctor/tags?page=1
