# CI/CD Health Checklist

A comprehensive checklist for assessing and maintaining GitLab CI/CD pipeline health.

## Pipeline Performance

- [ ] **Build Times**: Average pipeline duration < 15 minutes
- [ ] **Success Rate**: Pipeline success rate > 85%
- [ ] **Job Parallelization**: Critical jobs run in parallel where possible
- [ ] **Cache Utilization**: Dependencies and artifacts properly cached
- [ ] **Resource Usage**: No jobs consistently hitting memory/CPU limits

## Pipeline Reliability

- [ ] **Retry Logic**: Flaky tests have appropriate retry mechanisms
- [ ] **Failure Notifications**: Team notified immediately on failures
- [ ] **Rollback Capability**: Failed deployments can be rolled back quickly
- [ ] **Environment Isolation**: Test environments don't affect each other
- [ ] **Dependency Management**: External dependencies have fallbacks

## Code Quality Gates

- [ ] **Test Coverage**: Minimum 80% code coverage enforced
- [ ] **Linting**: Code style violations block merge
- [ ] **Security Scanning**: SAST/DAST scans pass before deployment
- [ ] **Performance Tests**: Critical paths have performance benchmarks
- [ ] **Documentation**: API changes require documentation updates

## Infrastructure Integration

- [ ] **IaC Validation**: Infrastructure changes validated in CI
- [ ] **Environment Parity**: CI environment matches production
- [ ] **Secret Management**: No secrets in code or CI logs
- [ ] **Monitoring Integration**: Deployments tracked in monitoring
- [ ] **Backup Verification**: Backup/restore procedures tested

## Development Workflow

- [ ] **Branch Protection**: Main branches protected with CI requirements
- [ ] **Merge Request Flow**: All changes go through MR with CI validation
- [ ] **Review Apps**: Preview environments for each MR
- [ ] **Automated Releases**: Semantic versioning and changelog generation
- [ ] **Rollout Strategy**: Canary/blue-green deployments configured

## Monitoring & Observability

- [ ] **Pipeline Metrics**: Duration, success rate, and frequency tracked
- [ ] **Job Analytics**: Slowest jobs identified and optimized
- [ ] **Error Tracking**: Failed job logs aggregated and analyzed
- [ ] **Cost Monitoring**: CI resource usage and costs tracked
- [ ] **Trend Analysis**: Performance degradation detected early

## Team Practices

- [ ] **CI Documentation**: Pipeline configuration well-documented
- [ ] **Onboarding Guide**: New developers can understand CI quickly
- [ ] **Best Practices**: Team follows established CI/CD patterns
- [ ] **Regular Reviews**: Monthly CI health review meetings
- [ ] **Continuous Improvement**: CI optimizations tracked and prioritized

## Emergency Preparedness

- [ ] **Incident Response**: Clear process for CI failures
- [ ] **Manual Override**: Emergency deployment process exists
- [ ] **Communication Plan**: Stakeholders notified of CI issues
- [ ] **Recovery Time**: CI can be restored within 30 minutes
- [ ] **Post-Mortems**: CI failures analyzed and documented

## Integration Health

- [ ] **JIRA Sync**: CI status reflected in issue tracking
- [ ] **Slack/Teams**: Build notifications in team channels
- [ ] **Deployment Tracking**: Releases linked to tickets
- [ ] **Artifact Management**: Build artifacts properly stored
- [ ] **Cross-Team Coordination**: Dependencies managed effectively

## Compliance & Security

- [ ] **Access Control**: CI permissions follow least privilege
- [ ] **Audit Logging**: All CI actions logged and retained
- [ ] **Compliance Scans**: Required compliance checks automated
- [ ] **Vulnerability Management**: CVEs tracked and patched
- [ ] **License Compliance**: Dependencies license-compliant
