docker pull from proget not working

jyip_5228

I have setup a nginx proxy with SSL certs setup. I am able to do docker pull and docker push, IF i do a docker login first with Admin for example. The anonymous permissions allows for the tasks of 'view and download packages' however I am unable to do a docker pull without any login.

I get the following error:
Error response from daemon: received unexpected HTTP status: 500 Internal Server Error

I am running the proget docker image with mssql and nginx.

Can we confirm if its possible to download docker images without login?

Thank you

Hello; you should be able to get the error message from Admin > Diagnostic center, inside of PRoGet. Hopefully that will give some insight as to where the underlying problem is...

hi,

i just checked the diagnostics center, I see other errors regarding feeds etc, but i do anything regarding docker pull.

Its weird i only get this issue when i'm not logged in as a user; unless this was by design.

Hello @jyip_5228,

Anonymous Docker feed access is supported, and a 500 response is (almost) always a bug.

In the ProGet advanced settings, you can set Diagnostics.FeedErrorLogging to the Docker feed's numeric ID and it should give more information about the failed request in the diagnostic center.

I'm getting the same issue. Output from diagnostic center is :

A 500 error occurred in (unknown feed): The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

Hello @aslepikas_5779 and @jyip_5228:

It looks like this happens in the processing of the Authorization: Bearer anonymous header. I've filed PG-1669 to fix this.

I updated to 5.2.25 where PG-1669 was fixed. This still appears to be an issue, same warning as above, only difference is the User Agent field

Is the stack trace actually empty? If not, it would be very helpful in tracking down this bug.

@ben

yeah, the stacktrace is empty

Hello; can you try updating ProGet? Actually, it seems 5.2.5 wasn't pushed/available at the until just a few days ago.

I did update proget manually, I built my own docker image for 5.2.25, deployed it, same issue (that version did fix the helm 3 support that I was waiting for as well). Today I've updated to 5.2.26, same 500 issue as before.

if you know where proget puts the logs in the linux container or a way to set the standard out more verbosely so I can get a better stack-trace for your guys, let me know.

Hello; this should get resolved in PG-1676, which is scheduled for the next maintence release.

5.2.27 has fixed the issue. Thank you so much!
