You might notice that your docker images are getting deleted by the system.
For example, you can see the below logs:
artifactory-access.log
2022-12-14T20:02:14.626Z [c22114f622fcbe72] [ACCEPTED DELETE] docker-local:get/my/image/tag/...for client : _system_ / .
artifactory-service.log
2022-12-14T20:02:20.801Z [jfrt ] [INFO ] [c22114f622fcbe72] [kerV2TagCleanupServiceImpl:269] [art-exec-7071 ] - Deleted docker tag docker-local:get/my/image:tag
The “_system_” user here is an internal Artifactory user used to run different Artifactory jobs such as clean up or authentication.
If this is the case, you can check whether “Max Unique Tags” is set for your docker repository.
If “Max Unique Tags” value is set, Artifactory will delete any old tags that exceed this limit.
