Network as Code
summary
Ticketmaster applies GitLab CI + AWX (Ansible Tower) to push YAML variables into Jinja templates, rendering vendor‑agnostic configs and enforcing PCI hardening across hundreds of devices. Workflow runs dev → staging (physical hardware) → production with pre/post checks, idempotency tests, and automatic rollback; daily jobs delete running config not present in repo. Demo shows config‑replace and diff-based fixes working end‑to‑end, catching unauthorized NTP entries and requiring pipelines to pass before merges. YAML variables + Jinja templates and idempotency + automated rollback are the core.
