Terraform — simulation environment (T4)
Sim fleet + observability on k3d. Cluster from ../../ansible/sim-cluster.yml. Executable T4 miniature (06 — Environments).
| Resource | Purpose |
|---|---|
StatefulSet drone × drone_count |
Virtual drones; pod names → DRONE_ID; shared /data lake |
Deployment exporter |
Prometheus exporter reading lake with DuckDB |
Deployment explorer + NodePort 30088 |
Partition tree + read-only SQL (prototype live mode) |
Deployment prometheus + NodePort 30990 |
Scrapes exporter |
Deployment grafana + NodePort 30300 |
Dashboard JSON from ConfigMap |
Usage
ansible-playbook ../../ansible/sim-cluster.yml # once: cluster + image
terraform init
terraform apply
terraform output # URLs
Scale without YAML edits:
terraform apply -var drone_count=9 -var speedup=4
Notes
image_pull_policy = "Never"— image imported by Ansible (k3d image import); no registry pull. Air-gap mirror.- Pod name → identity (StatefulSet ordinal).
kubectl delete pod= power cycle: new process, same identity, new flight ID. - Local state only — cluster disposable.
