I am using tags by applying them to nightly builds. Then later, I want to use the output of describe --tags --match <latest tag> to tell me how far from the nightly build my images are. This is for QA testing.
I just ran into an error in a clone that is older than the current tag. I ran git fetch --tags, so I see the tag in git tag output, but when I run git describe --tags --match <tagname>, I get fatal: No tags can describe <head sha1 version number>. I cannot do a git pull to update the workspace at this point. Why does this happen and is there a workaround? Thanks very much
