If you are running a private v2 docker registry, and you are storing your data on disk, running this script from the machine where the data lives will let you fully delete an image or tag

@joey-jihua yes, i was able to replicate what is probably your issue after messing around with a unit test for awhile. i think what's likely going on is that the registry is caching some state in memory about what data it has stored, so when we push a tag, delete it out from under the registry without it knowing using the script, and then repush it, the registry may believe that it already has the layer in question, so it doesn't re-store it. If you delete line 143 from the test, the test fails. so the fix is to make sure your registry is down while you're running the script. thanks for the report. i had never actually seen an issue caused by keeping the registry running when using this script.
