# T01: Added chrysopedia-lightrag service to docker-compose.yml with Qdrant vector storage, Ollama embeddings, and DGX Sparks LLM config in .env.lightrag

**Added chrysopedia-lightrag service to docker-compose.yml with Qdrant vector storage, Ollama embeddings, and DGX Sparks LLM config in .env.lightrag**

## What Happened

Added the chrysopedia-lightrag service definition to docker-compose.yml between Ollama and FastAPI services. Uses ghcr.io/hkuds/lightrag:latest, binds port 9621, mounts persistent storage, depends on Qdrant and Ollama healthy. Created .env.lightrag with OpenAI-compatible LLM binding for DGX Sparks, Ollama embedding binding, Qdrant vector storage, NetworkX graph storage, JSON KV/DocStatus storage, and music production entity types. File is already git-ignored by the .env.* wildcard.

## Verification

All four verification checks passed: docker compose config renders the chrysopedia-lightrag service, exits 0 with no errors, and .env.lightrag is excluded from git tracking via the existing .env.* wildcard pattern.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `docker compose config 2>&1 | grep -q chrysopedia-lightrag` | 0 | ✅ pass | 500ms |
| 2 | `docker compose config > /dev/null 2>&1` | 0 | ✅ pass | 500ms |
| 3 | `grep -q 'env.lightrag|.env.*' .gitignore` | 0 | ✅ pass | 10ms |
| 4 | `git check-ignore -q .env.lightrag` | 0 | ✅ pass | 10ms |


## Deviations

Added explicit KV/DocStatus storage settings, SUMMARY_LANGUAGE, MAX_ASYNC, MAX_TOKENS, OLLAMA_EMBEDDING_NUM_CTX, and RERANK_BINDING based on upstream env.example review. Used env_file required:true.

## Known Issues

LLM_BINDING_API_KEY is a placeholder — must be set on ub01 before LLM requests will work.
