Occasional "unknown blob" while uploading release


Use case:

Automatically upload release when test has been passed successful


I have seen similar behavior as described in There was a problem uploading the images to the registry.

Jenkins jobs are setup to compile and test software. When all is okay, the software is combined into a resin docker image and uploaded to the resin backend.

Sometimes this upload process fails with the error message “Unknown blob”. The size of image is 2.3GB. Likelihood is approximately once per 20 upload.

To recover from this, then just upload the image again and all is good.
