Summary

Enables Container API operations (create, list, retrieve, delete) to be called through litellm proxy with full router support including load balancing, authentication, and fallbacks.

What's Added

1. Proxy Endpoints (litellm/proxy/container_endpoints/endpoints.py)

• POST /v1/containers - Create container
• GET /v1/containers - List containers
• GET /v1/containers/{container_id} - Retrieve container
• DELETE /v1/containers/{container_id} - Delete container

2. Router Integration

• Added 8 container methods to Router.initialize_router_endpoints() (router.py)
• Added container call types to factory_function Literal and async handler (router.py)
• Added early routing check for container operations that don't require model parameter (route_llm_request.py)

3. Request Processing

• Added container route types to common_request_processing.py
• Provider extraction using same pattern as Files API (header > query > body > default)

Usage Example

curl -X POST http://localhost:4000/v1/containers \
  -H "Authorization: Bearer sk-1234" \
  -H "Content-Type: application/json" \
  -d '{"name": "My Container"}'
