- K8s API ACL restricted to Tailscale CGNAT (100.64.0.0/10) + admin IPs
- CI and GPU pools: min_size=0 with lifecycle ignore_changes on size
so autoscaler manages actual node count without Terraform drift
- Add harden.sh script for post-provisioning security lockdown
(ACL setup, exposed service check, bucket ACL verify, registry visibility)
- Update smoke-test.sh default region to fr-par
Security audit results:
- All services ClusterIP only (no LoadBalancer/NodePort)
- No Ingress resources
- Container registry: private
- S3 buckets: HTTP 403 on anonymous access
- Gitea: all ports closed on public IP (Tailscale-only via security group)
- Kapsule nodes: no open ports on external IPs
