GitLab CI Artifact Upload Failed

The job failed to upload artifacts due to network issues or incorrect artifact paths.

Understanding GitLab CI

GitLab CI/CD is a powerful tool integrated within GitLab that automates the software development process. It allows developers to build, test, and deploy their code efficiently. By defining pipelines in a .gitlab-ci.yml file, teams can streamline their workflows and ensure consistent delivery of software.

Identifying the Symptom: Artifact Upload Failed

One common issue encountered in GitLab CI is the 'Artifact Upload Failed' error. This error typically occurs during the execution of a job when the system attempts to upload artifacts generated by the job but fails to do so. The error message might look something like this:

ERROR: Job failed: exit code 1
ERROR: Uploading artifacts to coordinator... failed id=12345 responseStatus=500 Internal Server Error

Exploring the Issue: Why Does Artifact Upload Fail?

The 'Artifact Upload Failed' error can arise due to several reasons, primarily network-related issues or misconfigured artifact paths. When the network connection is unstable or the specified paths for artifacts are incorrect, GitLab CI cannot successfully upload the artifacts to the server. This can disrupt the pipeline and prevent subsequent stages from accessing necessary files.

Network Issues

Network interruptions or slow connections can hinder the upload process. If the connection to the GitLab server is lost or unstable, the upload will fail.

Incorrect Artifact Paths

If the paths specified for the artifacts in the .gitlab-ci.yml file are incorrect or do not exist, GitLab CI will not be able to locate and upload the files.

Steps to Resolve the Artifact Upload Issue

To resolve the 'Artifact Upload Failed' error, follow these steps:

1. Verify Network Connection

  • Ensure that your network connection is stable and has sufficient bandwidth.
  • Check if there are any firewall rules or proxy settings that might be blocking the connection to the GitLab server.
  • Consider using a VPN if there are regional restrictions affecting your connection.

2. Check Artifact Paths

  • Review the .gitlab-ci.yml file to ensure that the paths specified under the artifacts section are correct.
  • Ensure that the files or directories you intend to upload actually exist at the specified paths.
  • Example configuration:
    artifacts:
    paths:
    - build/
    - coverage/
    expire_in: 1 week

3. Retry the Job

  • Once you have verified the network and paths, retry the job in GitLab CI to see if the issue persists.
  • Navigate to the job in your GitLab project and click on the 'Retry' button.
