I have a Nexus Docker Proxy Registry containing several hundred Docker Repositories. I want to use the Docker ‘_catalog’ API to retrieve the entire list. This is a “paged” interface meaning that the entire list cannot be retrieve with a single call. Using the “n” and “last” parameters, you are supposed to be able to retrieve “pages” of data. No matter what values I set for “n”, the interface only returns the first 100 entries.
Attached is an example with “n” set to 10. I replaced “https://” with “*******” so that this site would let me post this. I also removed “.” from the URLs.
Notice on the last item that no “Link” variable is returned indicating that Nexus has no more items to return.
Testing with page size = 10
