Short answer as I'm in a hurry but I ll edit this afternoon when I have more time.

It is basically because of the implantation of the Docker Registry.

See the implementation (https://github.com/docker/distribution/blob/master/registry/handlers/catalog.go)

But maybe we should let the user know that the maximum is up to 100 by request.

'last' parameter should be used as described in the API spec to go page by page.

+1 on @mnarusze comment : when provisionning data, if show all is selected, it should call the api in loop /v2/_catalog?n=&last=<100thRepoFound> with the last item found from previous search until no results are found

I can't really test it from work. If sometone with the issue can check with that PR, it would be nice.

@drallieiv any updates on this?

[binhex]

just tripped up on this myself, setting the number to something high works around the issue e.g. ...repositories/99999

but it would be nice to have the 'all' limit working as designed.
