Docker image push issue (no basic auth credentials)

Docker Hub
1

Hi everyone, I am facing some weird issue in regards to pushing docker images to the registry. The issue occurs randomly during CI builds. For context, my team’s tech stack consists of:

  1. Docker version 18.09.6, build 481bc77156
  2. Private SonaType Nexus artifact registry (Sonatype Nexus Repository - Binary & Artifact Management | Sonatype) running in our own datacenter based for hosting different builds including docker imges.
  3. TeamCity 2023.11.4 build 147586 (TeamCity: the Hassle-Free CI/CD Tool by JetBrains) on premise CI/CD automation tool.
  4. Red Hat Enterprise Linux Server 7.6 (Linux master 3.10.0-957.12.1.el7.x86_64) OS based agent nodes (where TeamCity CI/CD pipelines run.
  5. Docker Compose version v2.17.2

The issue is that during TeamCity builds, Docker randomly throws no basic auth credentials provided error even though Docker successfully logins into the registry at the start.

If I re-run the pipeline manually, it works just fine. It even works correctly during most of the automatic builds.Another thing that i’ve noticed is that when docker push fails. it shows the image with latest tag even though the custom image tag is already specified.Does someone have any idea why it is happening or has at least a partial idea.?

That is a very old version, more then 5 years old and could have many compatibility issues with recent registries or images.

This issue doesn’t appear in 99% of the builds. In some cases, it does. Upon rerunning the steps manually, it disappears.

I understand, but old Docker versions can have unexpected behavior, can be unstable. I can’t explain the error, but the old version is definitely something you should avoid.
