Dynamic 5G Core Infrastructure with FluxCD Terraform Controller
summary
Orange deploys an experimental 5G standalone core on AWS by reconciling Terraform through FluxCD Terraform Controller, reusing existing Terraform modules while adding GitOps features: multi-tenancy, drift detection, manual approvals, dependency ordering, and variable passing via Kubernetes ConfigMaps and Secrets. One-time resources like an AWS VPN Gateway are created once and referenced; new radio sites trigger per-site VPNs. Performance-sensitive UPFs land on a dedicated tainted node with Terraform runners pinned to it; deletion ordering and serialized complex variables prove the main operational gotchas.
