Hello, running into an issue where sporadically we are unable to pull a particular image from our docker hub proxy. IE docker pull mynexusurl:mynexusport/node:lts results in not found: manifest unknown: manifest unknown
this is odd as it worked literally yesterday [2021-12-21T21:14:35.314Z] + docker pull mynexusurl:mynexusport/node:lts [2021-12-21T21:14:35.314Z] lts: Pulling from node
now the only known variable is that in between the success case and now we had the service stop and upgrade nexus and restart. Is there a potential unsafe behavior in this causing some sort of corruption? Is there a way to fix it?
Or is this a known issue that can be worked around? I have verified that pulling directly from docker hub works just fine.
As this started happening I deleted the image from the cache thinking it would just get re-pulled. But it is still throwing the same error
The nexus logfile contains the following excerpt which I think has some similar noise from a diff image:
