ProGet GET requests not returning expected payload

[james.traxler_1560]

GET requests on https://our.proget.com/v2/qa-feed-1/library/nginx/manifest/latest with header Accept: application/vnd.docker.distribution.manifest.v1+json return a payload of type application/vnd.docker.distribution.manifest.v2+json which doesn’t contain the data we are expecting (i.e. we can’t explore the layers of the manifest through the requested version of this manifest).

See screenshot:

Note: Regarding requested URL: /api/registries/1 – part of the URL is only a backend proxy, passing the request as-is to the Proget API – basically transforming http://localhost:9000/api/registries/1/v2/… to https://our.proget.com/v2/…

This issue was mentioned on forum topic 3541, but we thought it best to just log as a separate topic.

Hi @james-traxler_1560,

I'm not really sure I totally understand the issue, or how to resolve it... but I'll explain how a GET manifest request to your URL would work.

Basically, ProGet returns whatever manifest file you uploaded, or whatever was downloaded via the connector. We do not generate the manifest files, or pay attention to the Accept request header.

I understand that application/vnd.docker.distribution.manifest.list.v2+json is a "fat manifest", which is basically a manifest that points to other manifests on different architectures. So you don't know exactly what image you'll get until you install it on the machine.

So if you want to inspect layers, you would first need to decide which manifest to use, I guess

Cheers,
Alana
