Best Practices

This section highlights recommended practices for operating GitLab efficiently and securely.

Admin best practices

  • Keep GitLab updated with the latest stable patches
  • Use backups and disaster recovery procedures
  • Enforce strong authentication and least-privilege access
  • Monitor logs, runner health, and system resources
  • Use protected branches for critical code paths

CI/CD best practices

  • Keep pipeline YAML in source control
  • Use small, targeted jobs
  • Define clear stages and dependencies
  • Reuse caches and artifacts for performance
  • Fail fast on syntax or build errors
  • Use environments and approvals for production

Security best practices

  • Restrict pipeline permissions
  • Avoid storing secrets in project files
  • Review dependencies and scan for vulnerabilities
  • Use protected variables and masked secrets
  • Require code review before merge

Team workflow recommendations

  • Standardize branch naming conventions
  • Require merge requests for all changes to protected branches
  • Add reviewers for critical code changes
  • Define a release and rollback plan

Summary

Good GitLab administration and CI/CD design are largely about consistency, security, and visibility across the whole software lifecycle.
