Chat route with vLLMv3.6+
Configure a chat route using a self-hosted vLLM server.
Prerequisites
- A running vLLM server
Environment variables
-
VLLM_UPSTREAM_URL: The full URL of your vLLM server, including the path (for example, http://your-vllm-host:8000/v1/chat/completions).
Add this section to your kong.yaml configuration file:
