4. Advanced Features and Integrations (For Advanced Users)

CI/CD Integrations

Backstage integrates seamlessly with tools like:

Jenkins: Add Jenkins pipelines to your workflows.
GitHub Actions: Monitor workflows with the GitHub plugin.
CircleCI: Integrate CircleCI pipelines for build management.

Multi-Environment Deployments

Use app-config.local.yaml for environment-specific configurations:

app:
  baseUrl: http://staging.example.com

Governance Best Practices

Define clear plugin development guidelines.
Use monitoring tools like Prometheus to track performance.

5. Security Considerations

Role-Based Access Control (RBAC)

Restrict access to sensitive features with RBAC:

permissions:
  policies:
    - name: adminPolicy
      allow:
        - 'admin:*'
    - name: readOnlyPolicy
      allow:
        - 'catalog:read'

Securing Sensitive Data

Store secrets in environment variables:bashCopy codeexport GITHUB_TOKEN=your_token_here
Audit dependencies regularly for vulnerabilities.

6. Troubleshooting Common Issues

Issue 1: Installation Errors

Solution: Clear dependencies and reinstall:

rm -rf node_modules && yarn install

Issue 2: Plugin Not Loading

Solution: Verify plugin registration in App.tsx.

Issue 3: Authentication Failures

Solution: Ensure OAuth credentials are correctly configured in app-config.yaml.
