·2 min read·246 words
NetDevOps : application of pratiques DevOps au network. Git for configs, CI/CD for déploiements, tests automatisés, GitOps workflow. Transformation culturelle + technique. Guide NetDevOps 2026 : tools, pipeline exemple, quick wins.
Principes NetDevOps
- Config = code : tout dans Git
- CI/CD : pipeline automatisé lint + test + deploy
- Tests : validation pré-deploy (Batfish)
- GitOps : source of truth = Git repo
- Collaboration : PR reviews, pair programming
- Continuous improvement
Tools stack type
- Git : GitLab, GitHub, Bitbucket
- CI/CD : GitLab CI, GitHub Actions, Jenkins
- Source of Truth : NetBox, Nautobot, Infoblox
- Automation : Ansible, Nornir, Terraform
- Testing : Batfish, SuzieQ, pytest
- Monitoring : Prometheus + Grafana
Pipeline exemple
- 1. Engineer crée branch feature
- 2. Modifie YAML config source of truth
- 3. Push + Pull Request
- 4. CI : lint YAML + Ansible syntax + Batfish
- 5. Review par pair
- 6. Merge → auto-deploy staging
- 7. Tests post-deploy (ping, BGP status)
- 8. Manual approval → deploy prod
- 9. Monitoring continuous
Batfish
- Simulation config network avant deploy
- Détecte : routing loops, ACL conflicts, reachability issues
- Open source
- Intégration CI : pybatfish
Quick wins
- Backup configs en Git (30 min setup)
- Linting YAML (1h)
- Ansible Vault for secrets (2h)
- Staging lab VM (1j)
- Pipeline CI basique (3j)
Transformation culturelle
- NetOps ≠ NetDevOps : changement mentalité requis
- Form factorion Python + Git + YAML
- Peer review
- Blameless post-mortems
- Documentation vivante
