by swagger file

This API has the same issue as #7 , #20 and #21

[moooofly]

a wired case by swagger UI

create a global label by swagger UI

but you will find nothing in harbor UI

run it again, you will get

<== Rsp Body: label 3000 not found

[#550#root@ubuntu-1604 /go/src/github.com/moooofly/harborctl]$

Conclusion

This issue must be related with --deleted parameter which means "Mark the label is deleted or not."

If you call this API with --deleted, you actually create a label that has been marked "Deleted", and you can get it by any means.

This behavior will cause a obscure problem:

• create a label with --deleted and succeed.
• some day after, you want to get it back, but only get "404 Not Found" (you will keep doubting yourself).
• try to create this label with the same parameters (actually any composition will fail). You can do nothing, even make a deletion on it.
• you can only create another label with totally different parameters composition (without --deleted this time).

Here is the question: What is the role of --deleted in fact?
