Add attributes and filter query params to 'List repository tags' endpoint

[pflannery]

Would be great if we could only fetch the data we need from the 'List repository tags' endpoint to make it faster and get smaller page download sizes.

Currently my project versionlens uses this endpoint to fetch all tags for a repository but has to limit the requests to a maximum of 3 pages because it's just too slow for larger repositories.

This example fetch url takes around 0.5 secs to fetch one page containing only 100 results (almost 30kb).

NOTE

the undocumented name query param feature for this endpoint isn't useful for versionlens because versionlens
needs to determine if their is a major, minor or patch update available

Is it possible to add the attributes and filter query params to this endpoint? e.g. attributes=name,digest&filter=tag_status eq "active"

thanks

Thanks for the feedback! FYI - "status" is nothing more than "was pushed less than 1 month ago". If you need this, you can also just sort by newest then stop paging after you start seeing tags older than 1 month.

We can evaluate these options, but generally speaking, adding complexity on the querying side is going to make performance even worse given the volume of scraping that goes on. I'm curious if you are able to do any caching of results on your end? I assume these requests are also all unauthenticated due to being a plugin?

@jcarter3 Thanks for your reply

Yes versionlens caches but the speed hit still occurs when using with docker compose with multiple images or multiple FROM clauses in dockerfiles.

Versionlens supports authorized requests but I don't see this making it faster due to the 100 tags per page limit

Maybe instead there could be a dedicated endpoint for just tags with their related digests? would be awesome
