GitHub Actions CI Failures

This page targets engineers searching for specific troubleshooting steps when a GitHub Actions run fails. The content focuses on practical evidence collection and debugging steps.

What is a GitHub Actions CI failure​

A CI failure in GitHub Actions is any workflow or job that exits with a non-zero status. Failures might be unit test failures, linting errors, or runner environment problems.

Why this problem happens​

  • Broken tests or build scripts
  • Missing secrets or environment variables in the runner
  • Network or runner resource failures

How engineers debug this​

  1. Fetch the workflow run logs and identify the failing step.
  2. Record the run id, job id, and commit SHA that triggered the run.
  3. Re-run the workflow with debug logging or locally reproduce using the runner container.

Best practices​

  • Emit structured logs and artifacts to make failure evidence searchable.
  • Keep secrets and environment configuration consistent across runner tiers.

Tools that help​

OctoLaunch can ingest GitHub Actions events and help link a failing run to a deployed artifact and related incident evidence.

FAQ​

  • Q: How can I preserve workflow logs for postmortems?
    • A: Upload logs as artifacts and store the artifact link in the incident record.
  • Q: What runtime info should I capture from runs?
    • A: Runner image, environment variables, and resource usage metrics.
