Thu, 24 Jul 2025 00:00:00 +0000

You’ve been there. You push your code, a new CI/CD pipeline kicks off in GitLab, and you wait for that satisfying green checkmark. Instead, you get a dreaded red ‘X’. The pipeline failed. Digging into the job logs, you find a cryptic message: “ERROR: Job failed (system failure): prepare environment: exit code 1”. The culprit is often the GitLab Runner executor—the very engine responsible for running your jobs—failing in its environment.
