# T02: Deployed LightRAG on ub01, fixed healthcheck (curl missing from image, switched to Python urllib), verified entity extraction (10 entities, 9 relations) and query returning accurate music production results

**Deployed LightRAG on ub01, fixed healthcheck (curl missing from image, switched to Python urllib), verified entity extraction (10 entities, 9 relations) and query returning accurate music production results**

## What Happened

Created bind mount directory on ub01, copied config files via scp, set real LLM API key. Container started but healthcheck failed because LightRAG image lacks curl — switched to Python urllib with 127.0.0.1. Entity extraction processed music production text about COPYCATT's bass sound design, extracting 10 entities and 9 relationships. Query returned accurate response identifying Serum, OTT, and Valhalla Room. All existing services remained healthy.

## Verification

Health endpoint returns 200, container reports healthy, entity extraction returned 10 entities + 9 relations, query returned correct music production entities, all 10 existing Chrysopedia services still healthy, all 3 slice-level checks pass.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `ssh ub01 'curl -sf http://localhost:9621/health'` | 0 | ✅ pass | 200ms |
| 2 | `ssh ub01 'docker ps --filter name=chrysopedia-lightrag ... | grep -q healthy'` | 0 | ✅ pass | 300ms |
| 3 | `ssh ub01 'curl -sf -X POST http://localhost:9621/documents/text ...'` | 0 | ✅ pass | 500ms |
| 4 | `ssh ub01 'curl -sf -X POST http://localhost:9621/query ...'` | 0 | ✅ pass | 8000ms |
| 5 | `docker compose config 2>&1 | grep -q chrysopedia-lightrag` | 0 | ✅ pass | 500ms |
| 6 | `docker compose config > /dev/null 2>&1` | 0 | ✅ pass | 500ms |
| 7 | `git check-ignore -q .env.lightrag` | 0 | ✅ pass | 10ms |


## Deviations

Changed healthcheck from curl to Python urllib because LightRAG Docker image does not include curl.

## Known Issues

Qdrant client v1.15.1 in LightRAG image warns about server v1.13.2 mismatch but functions correctly. Files deployed via scp — ub01 repo has uncommitted changes.
