Dear ONAP team, As mentioned today by Helen on the TSC call, it seems that we have experienced an issue with Nexus3 where the dependency images "disappear" for some moment and come back.
I was investigating this issue a little bit closer, let me try to explain what I think is happening with Gary's example. In his case, onap/aaf/aaf_cm/manifests/2.1.0-SNAPSHOT <https://nexus3.onap.org/repository/docker.snapshot/v2/onap/aaf/aaf_cm/manifests/2.1.0-SNAPSHOT> (among other AFF images) disappeared on the 9th of may and re-appeared the same day after few hours. Looking at the job that pushed this image https://jenkins.onap.org/view/aaf/job/aaf-authz-master-docker-java-shell-daily/ , seems like AAF bins were successfully pushed on the 7th and on the 9th but failed on the 8th. At the same time, I believe this rule kicked in: This rule seems to be scanning for dependencies and will remove any snapshot not being referenced by anyone every day. https://help.sonatype.com/repomanager3/configuration/system-configuration#SystemConfiguration-TypesofTasksandWhentoUseThem There is not much configuration on this rule to be able to explain what is actually looking for, but I believe this is the cause. This rule might have removed the AAF image pushed on the 7th and, since the AAF jenkins job failed to push a new image on the 8th, the rule might have remove it for some time. Then the job that kicked in on the 9th brought it back. So, here is my suggestions: - We need to make sure our daily jobs are healthy and address any failures on a daily basis to avoid this issue in future - Keeping this rule in place is helping us keep stability on disk space. If we were to remove it we will have grater issues to address. - I have confirmed with Andy and we prefer keeping this known configuration in place to avoid disk usage issues. Let me know if I was clear on my explanation and we can see if keeping an eye on the dailies helps us reducing this occurrences. Thanks a ton! Jess
