Production vLLM deployment of DeepSeek Coder V2 236B on RTX Spark. Configs, systemd, TLS, observability.
Install
Install vLLM via pip/docker/apt as appropriate. Verify GPU visibility with nvidia-smi.
- # vLLM install
- pip install vllm
Config
Optimized vLLM config for DeepSeek Coder V2 236B at Q3_K_M: batch, KV cache dtype, and parallelism knobs.
Systemd unit
[Unit] Description=vLLM for DeepSeek Coder V2 236B — [Service] ExecStart=/usr/bin/vllm serve deepseek-coder-v2-236b --port 8000 — Restart=always.
nginx + TLS
Terminate TLS at nginx with a Let's Encrypt cert, rate-limit at 20 req/s per IP, and proxy to the local vLLM port.
Observability
Scrape vLLM Prometheus metrics into Grafana; watch tokens_per_second, batch_size, and kv_cache_usage.
Frequently asked questions
Is vLLM the fastest for DeepSeek Coder V2 236B?
Yes for throughput; TensorRT-LLM edges it on p50 latency.
Can I run multiple models with one instance?
Yes with --served-model-name and multi-LoRA.
