Docker token expires causing pipeline to fail

Describe your question in as much detail as possible:
Using the docker executor w/ DOCKER_AUTH_CONFIG as a pipeline variable (Using Docker images | GitLab)

Docker auth token expires and causes the pipeline to fail with this error:
"Using Docker executor with image privateimage:v1 ERROR: Preparation failed: Error response from daemon: Head unauthorized authentication required (docker.go:143:0s)

  • What are you seeing, and how does that differ from what you expect to see?
    I’m able to solve the error by logging into my private registry and copying the docker configuration into my DOCKER_AUTH_CONFIG variable.

  • What version are you on? Are you using self-managed or
    Self-managed Gitlab. Using docker executor


  name = "docker"
  url = ""
  token = "HHsjdjjcjckdjkss"
  executor = "docker"
    tls_verify = false
    image = "ruby:2.7"
    privileged = false
    disable_cache = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0
  • GitLab (Hint: /help):
  • Runner (Hint: /admin/runners):
  • Add the CI configuration from .gitlab-ci.yml and other configuration if relevant (e.g. docker-compose.yml)

  • What troubleshooting steps have you already taken? Can you link to any docs or other resources so we know where you have been?

Thanks for taking the time to be thorough in your request, it really helps! :blush:
