Corrupted docker images: error pulling image configuration: unknown blob
-
We're using ProGet 4.7.11 and have started to notice that often after we publish a new revision of a docker image to proget's repository, that previous versions of the image are corrupted and cannot be used anymore. The error from docker is:
error pulling image configuration: unknown blob
There is no workaround but to update our code to use the latest revision of the image. We're using the default package store and disk path. I believe we saw this error in a previous version of Proget, 4.7.6, but we're seeing it a lot more as we are producing more and more revisions of an image in docker.
Seen with docker mac client as well as docker in our ec2 instance. That's actually where we notice it: we're using ECS with Jenkins and the jenkins build hangs as it tries to start an older image (i.e. not latest) and can't because proget returns the "unknown blob" error.
Here is example output from docker pull:

We are currently investigating this in a ticket from another user, and will try to update this when we have more information

Hello Jeff,
There is currently a bug in the FeedCleanup task for Docker feeds. PG-1030 has been fixed for the next version of ProGet, but until then, disable the FeedCleanup task for any Docker feeds in
/administration/scheduled-tasks.
