Root Cause

Docker registry requires authentication to pull or push images.

generic

Workarounds

  1. 96% success Login to the registry: docker login <registry-url> 
    Stores credentials in ~/.docker/config.json

    Sources: https://docs.docker.com/reference/cli/docker/login/

  2. 90% success For CI/CD, use a credential helper or environment variables 
    echo $TOKEN | docker login -u user --password-stdin

Dead Ends

Common approaches that don't work:

  1. Making the registry public 90% fail

    Exposes all images to anyone; security risk

  2. Storing credentials in Dockerfile 95% fail

    Credentials are baked into the image layer and visible to anyone
