Default OLLAMA_MODEL to embeddinggemma:300m in docker-compose#1
Merged
Conversation
Adds OLLAMA_MODEL env var to the code_nexus service with embeddinggemma:300m as the default. Matches the existing 768-dim vector size and lets users override with `OLLAMA_MODEL=... docker-compose up`.
The published image doesn't include curl, so every healthcheck probe failed with "executable file not found" and the container was reported unhealthy even though Phoenix on :4100 was serving fine. Switch to the same bash /dev/tcp probe qdrant uses.
