Terraform — ground warehouse (T3)
The stationary half of the system: the historical warehouse that receives sealed partitions after every flight (03 — Storage tiers). It is the longest-lived, most conventional infrastructure in the design — and therefore the most natural Terraform territory.
Runs in the same k3d cluster as ../sim-env but in its own
namespace with its own state: the fleet is disposable, the warehouse is not,
and the two lifecycles must never share a terraform destroy.
| Resource | Purpose |
|---|---|
Deployment minio + PVC + NodePort 30901 |
Object-store facade of the warehouse for downstream consumers (training pipelines, replay) |
CronJob offload |
Post-flight offload: copies Hive partitions verbatim from the fleet lake (T1) into the warehouse (T3), then mirrors into MinIO |
Deployment warehouse-explorer + NodePort 30089 |
Second explorer instance over the warehouse path — historical read-only SQL across all flights |
Usage
terraform init
terraform apply
terraform output
After a couple of offload runs, the warehouse explorer shows the same partition tree as the live lake but accumulated across flights — the T1 layout is the T3 layout, which is the whole point: no transform step, no schema drift, DuckDB queries work identically on both ends.
Simulation vs production
- The CronJob compresses "drone lands, docks, offloads, prunes" into a periodic rsync-style copy. Production offload is event-driven per docking and verifies checksums from the flight's partition manifest before pruning the on-board lake.
- MinIO credentials here are throwaway defaults; production credentials are sealed per site and never in state or VCS.
