Apparently you can upload 0-size content wihtout GCS reportin any errors back to you. This is something a lot of our users experienced and reported. See here for at least one example: github.com/distribution/issues/3018 This sets tbe MD5 sum on the uploaded content which should rectify things according to the docs: https://pkg.go.dev/cloud.google.com/go/storage#ObjectAttrs Signed-off-by: Milos Gajdos <milosthegajdos@gmail.com>

Would it be worth adding a comment here (to save future visitors from having to go through git history?

LOL autocorrect; it's really git I meant, not hot (edited) 😆

Apparently, you can upload 0-size content without GCS reporting any errors back to you. Registry operations fail in these situations
This is something a lot of our users experienced and reported. See here for at least one example:
#3018
This PR sets the MD5 sum on the uploaded content which should rectify things according to the docs:
https://pkg.go.dev/cloud.google.com/go/storage#ObjectAttrs
The alternative would be to set
CRC32Cbut that's not been verified unlike the MD5 which is used by GitLab in their registry.Closes: #3018
