Alert Slack on GitLab CI/CD pipeline failures

Overview

Never miss a broken build. This workflow monitors GitLab CI/CD pipelines and sends immediate Slack alerts when a pipeline fails, including the commit, author, and failure details.

How it works

1. GitLab webhook triggers on pipeline status change
2. Failed pipeline details are extracted (branch, commit, author)
3. Error logs are summarized for quick diagnosis
4. A formatted alert is sent to the team's Slack channel

Key features

• Pipeline stage identification (which stage failed)
• Direct links to failed jobs
• Author mention for quick resolution
• Configurable severity filtering

Use cases
