I'd like to be able to identify how much space is used by all images with a certain tag. The idea for this, is to be able to tell which dev team is consuming "too much" space.
Each dev team, will use a particular container TAG that will help identify them.
I tried using gcloud cli for this matter but I was unable to find a way to achieve such thing.
Any ideas?
As of the moment, you can only determine the size of Google Artifact Registry per image. You can determine the size in two ways:
gcloud artifacts docker images list
You may check this documentation on listing images for additional information.
You may also want to file this as a feature request through this link. There's no specific ETA on this but you can check its progress by following the ticket once it's created.
