Is there a limit for the length of docker tags?

[jorisjumanne]

I seem to have found a limit for the length of tags of docker images to be shown in Harbor. A very long tag name of around 70 characters doesn't show up in the harbor UI, where a tag length of 15 characters does.

Does a limit apply and, if so, what is this limit? I can then take it into account while settings tags for my images and no longer have tagless images in Harbor.

I would like to convert this as a bug, and we will have a debug.

Dear @wy65701436 I think this issue can be closed. I found out that images were being untagged because new versions were uploaded. The untagged images were being cleaned up by harbor's garbage collection.
