Help make proxy non-standard - external nginx proxy

[IwanSE]

Hello everybody!

I'm solving a non-standard problem.

I need to make a project proxy - harbor.domain.zone/project-name.

The goal is to configure nginx to perform pull.
We are temporarily unable to perform regular docker pull - docker pull harbor.domain.zone/project-name/kubectl:latest

I'm trying to configure it using this guide - Link
I get the error:

docker pull some-name.domain.tech/kubectl:latest
Error response from daemon: unauthorized: unauthorized to access repository: temp-proxy2nexus/kubectl, action: pull: unauthorized to access repository: temp-proxy2nexus/kubectl, action: pull

Please help us find a solution together, I think that such a solution will help many!
Sorry for the personal note, but maybe you can help, I will be very grateful!
@Vad1mo, @OrlinVasilev, @AllForNothing, @wy65701436 Maybe you know in which direction to investigate this non-standard case, I will be grateful to any feedback.

Hi @IwanSE, I'll convert that to discussion as issues are to report problems and discussion is more suitable for this!
