CI/CD Secrets

Overview

CI/CD secrets protect deployment credentials, registry tokens, and signing keys used in automation pipelines.

Secure Pipeline Practices

• Use built-in secret stores from CI platforms
• Mask secrets in logs
• Restrict secret usage by environment and branch
• Use short-lived tokens when possible

Practical Example

steps:
  - name: Deploy
    env:
      API_TOKEN: ${{ secrets.DEPLOY_API_TOKEN }}

Production Example

Teams commonly separate non-production and production credentials with approval gates to prevent accidental promotion misuse.

Common Pitfalls

• Echoing secrets in debug output
• Reusing one token across many pipelines
• Missing secret rotation during personnel changes

Key Takeaways

• CI/CD secret handling is a critical supply-chain control.
• Runtime-only injection reduces leakage risk.
• Segmentation and rotation improve security posture.
