TKE AI Playbook

English | 中文

Project Overview

This project provides Kubernetes-based scripts for AI large language model (LLM) operations, including model downloading, inference service deployment, and performance benchmarking, enabling end-to-end AI workflows on Tencent Kubernetes Engine (TKE).

Prerequisites

1. Kubernetes cluster (recommended v1.28+)
2. Tencent Cloud CFS storage (or compatible storage solution)
3. GPU nodes (3 * H20 nodes used in this project)

Capabilities

Model Download

Use the Model Download Utility to download models to CFS storage for reuse across inference services.

Inference Service Deployment

• dynamo: NVIDIA's distributed inference framework (open-sourced at GTC 2025), supporting multiple inference engines including TRT-LLM, vLLM, and SGLang.

Performance Benchmarking

• LLM Benchmark Suite

Examples

dynamo

Single-Node PD Disaggregation

Prerequisites:

• 1 x 8 GPU Node.

Deploys:

• 1 x VllmWorker (4 GPUs for decode phase)
• 4 x PrefillWorker (1 GPU each for prefill phase)
