- Test thoroughly — use Molecule and check mode
- Document decisions — future team members will thank you
- Version control — commit everything to git
- Security first — use Vault, limit access, audit actions
Common Mistakes
| Mistake | Impact | Fix |
|---|---|---|
| Over-engineering | Complexity, maintenance burden | KISS principle |
| No testing | Broken deployments | Molecule + CI/CD |
