使用 NVIDIA Dynamo 安装
本指南分步说明如何将 vLLM Semantic Router 与 NVIDIA Dynamo 集成。
关于 NVIDIA Dynamo
NVIDIA Dynamo 是面向大语言模型推理的高性能分布式推理平台。Dynamo 通过智能路由与缓存机制,帮助优化 GPU 利用率并降低推理延迟。
主要特性
- 分离式服务(Disaggregated Serving):Prefill 与 Decode 工作进程分离,更好利用 GPU
- KV 感知路由:将请求路由到具备相关 KV 缓存的工作进程,优化前缀缓存
- 动态扩缩容:Planner 组件按负载自动扩缩
- 多级 KV 缓存:GPU HBM → 系统内存 → NVMe,分层管理缓存
- 工作进程协调:etcd 与 NATS 用于分布式注册与消息队列
- 后端无关:支持 vLLM、SGLang、TensorRT-LLM 等后端
集成收益
将 vLLM Semantic Router 与 NVIDIA Dynamo 结合可获得:
- 双层智能:Semantic Router 在请求层做模型选择与分类;Dynamo 在基础设施层优化工作进程选择与 KV 缓存复用
- 智能模型选择:Semantic Router 理解内容并路由到合适模型;Dynamo 的 KV 感知路由器选择最优工作进程
- 双层缓存:语义缓存(请求级,Milvus)与 KV 缓存(token 级,Dynamo 管理)叠 加,降低延迟
- 安全增强:PII 与越狱检测在请求到达推理工作进程前过滤
- 分离式架构:Prefill/Decode 分离与 KV 感知路由,降低延迟、提高吞吐
架构
本部署采用 分离式路由器部署 模式并 启用 KV 缓存,Prefill 与 Decode 工作进程分离以更好利用 GPU。

部署模式
本指南部署 分离式路由器 且 启用 KV 缓存(frontend.routerMode=kv)。推荐该配置以获得最佳性能:KV 感知路由可在请求间复用已计算的 attention;Prefill/Decode 分离可最大化 GPU 利用率。
依据 NVIDIA Dynamo 部署模式,Helm Chart 支持两种模式:
聚合模式(默认)
工作进程 同时处理 Prefill 与 Decode。部署更简单,所需 GPU 更少。
# No workerType specified = defaults to "both"
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[1].model.path=Qwen/Qwen2-0.5B-Instruct
- 工作进程在 ETCD 中注册为
backend组件 - 无
--is-prefill-worker标志 - 每个工作进程可处理完整推理请求
分离模式 (高性能)
Prefill 与 Decode 工作进程分离,更好利用 GPU。
# Explicit workerType = disaggregated mode
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[0].workerType=prefill \
--set workers[1].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[1].workerType=decode
| Worker | 标志 | ETCD 组件 | 角色 |
|---|---|---|---|
| Prefill | --is-prefill-worker | prefill | 处理输入 token,生成 KV 缓存 |
| Decode | (无特殊标志) | backend | 生成输出 token,仅处理 decode 请求 |
分离模式下仅 Prefill 工作进程使用 --is-prefill-worker。Decode 工作进程使用默认 vLLM 行为(无特殊标志)。KV 感知前端将 Prefill 请求路由到 prefill 工作进程,Decode 请求路由到 backend 工作进程。
前置条件
GPU 要求
本部署至少需要 3 块 GPU:
| 组件 | GPU | 说明 |
|---|---|---|
| Frontend | GPU 0 | Dynamo Frontend,KV 感知路由(--router-mode kv) |
| Prefill Worker | GPU 1 | 推理 Prefill 阶段(--worker-type prefill) |
| Decode Worker | GPU 2 | 推理 Decode 阶段(--worker-type decode) |
所需工具
开始前请安装:
NVIDIA 运行时配置(一次性)
将 Docker 默认运行时设为 NVIDIA:
# Configure NVIDIA runtime as default
sudo nvidia-ctk runtime configure --runtime=docker --set-as-default
# Restart Docker
sudo systemctl restart docker
# Verify configuration
docker info | grep -i "default runtime"
# Expected output: Default Runtime: nvidia
步骤 1:创建支持 GPU 的 Kind 集群
创建带 GPU 支持的本地 Kubernetes 集群,任选其一:
选项 1:快速设置(外部文档)
按官方 Kind GPU 文档快速创建:
kind create cluster --name semantic-router-dynamo
# Verify cluster is ready
kubectl wait --for=condition=Ready nodes --all --timeout=300s
GPU 支持见 Kind GPU 文档(extra mounts 与 NVIDIA device plugin 等)。
选项 2:完整 GPU 设置(E2E 流程)
与仓库 E2E 测试相同的流程,包含 Kind 内 GPU 所需的全部步骤。
2.1 使用 GPU 配置创建 Kind 集群
# Create Kind config for GPU support
cat > kind-gpu-config.yaml << 'EOF'
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
name: semantic-router-dynamo
nodes:
- role: control-plane
extraMounts:
- hostPath: /mnt
containerPath: /mnt
- role: worker
extraMounts:
- hostPath: /mnt
containerPath: /mnt
- hostPath: /dev/null
containerPath: /var/run/nvidia-container-devices/all
EOF
# Create cluster with GPU config
kind create cluster --name semantic-router-dynamo --config kind-gpu-config.yaml --wait 5m
# Verify cluster is ready
kubectl wait --for=condition=Ready nodes --all --timeout=300s
2.2 在 Kind Worker 中准备 NVIDIA 库
从宿主机复制 NVIDIA 库到 Kind worker 节点:
# Set worker name
WORKER_NAME="semantic-router-dynamo-worker"
# Detect NVIDIA driver version
DRIVER_VERSION=$(nvidia-smi --query-gpu=driver_version --format=csv,noheader | head -1)
echo "Detected NVIDIA driver version: $DRIVER_VERSION"
# Verify GPU devices exist in the Kind worker
docker exec $WORKER_NAME ls /dev/nvidia0
echo "✅ GPU devices found in Kind worker"
# Create directory for NVIDIA libraries
docker exec $WORKER_NAME mkdir -p /nvidia-driver-libs
# Copy nvidia-smi binary
tar -cf - -C /usr/bin nvidia-smi | docker exec -i $WORKER_NAME tar -xf - -C /nvidia-driver-libs/
# Copy NVIDIA libraries from host
tar -cf - -C /usr/lib64 libnvidia-ml.so.$DRIVER_VERSION libcuda.so.$DRIVER_VERSION | \
docker exec -i $WORKER_NAME tar -xf - -C /nvidia-driver-libs/
# Create symlinks
docker exec $WORKER_NAME bash -c "cd /nvidia-driver-libs && \
ln -sf libnvidia-ml.so.$DRIVER_VERSION libnvidia-ml.so.1 && \
ln -sf libcuda.so.$DRIVER_VERSION libcuda.so.1 && \
chmod +x nvidia-smi"
# Verify nvidia-smi works inside the Kind worker
docker exec $WORKER_NAME bash -c "LD_LIBRARY_PATH=/nvidia-driver-libs /nvidia-driver-libs/nvidia-smi"
echo "✅ nvidia-smi verified in Kind worker"
2.3 部署 NVIDIA Device Plugin
# Create device plugin manifest
cat > nvidia-device-plugin.yaml << 'EOF'
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: nvidia-device-plugin-daemonset
namespace: kube-system
spec:
selector:
matchLabels:
name: nvidia-device-plugin-ds
template:
metadata:
labels:
name: nvidia-device-plugin-ds
spec:
tolerations:
- key: nvidia.com/gpu
operator: Exists
effect: NoSchedule
containers:
- image: nvcr.io/nvidia/k8s-device-plugin:v0.14.1
name: nvidia-device-plugin-ctr
env:
- name: LD_LIBRARY_PATH
value: "/nvidia-driver-libs"
securityContext:
privileged: true
volumeMounts:
- name: device-plugin
mountPath: /var/lib/kubelet/device-plugins
- name: dev
mountPath: /dev
- name: nvidia-driver-libs
mountPath: /nvidia-driver-libs
readOnly: true
volumes:
- name: device-plugin
hostPath:
path: /var/lib/kubelet/device-plugins
- name: dev
hostPath:
path: /dev
- name: nvidia-driver-libs
hostPath:
path: /nvidia-driver-libs
EOF
# Apply device plugin
kubectl apply -f nvidia-device-plugin.yaml
# Wait for device plugin to be ready
sleep 20
# Verify GPUs are allocatable
kubectl get nodes -o custom-columns=NAME:.metadata.name,GPU:.status.allocatable.nvidia\\.com/gpu
echo "✅ GPU setup complete"
Semantic Router 仓库包含自动化 E2E,可自动完成上述 GPU 环境:
make e2e-test E2E_PROFILE=dynamo E2E_VERBOSE=true
将创建带 GPU 的 Kind 集群、部署组件并运行测试套件。
步骤 2:安装 Dynamo 平台
部署 Dynamo 平台组件(etcd、NATS、Dynamo Operator):
# Add the Dynamo Helm repository
helm repo add dynamo https://nvidia.github.io/dynamo
helm repo update
# Install Dynamo CRDs
helm install dynamo-crds dynamo/dynamo-crds \
--namespace dynamo-system \
--create-namespace
# Install Dynamo Platform (etcd, NATS, Operator)
helm install dynamo-platform dynamo/dynamo-platform \
--namespace dynamo-system \
--wait
# Wait for platform components to be ready
kubectl wait --for=condition=Available deployment -l app.kubernetes.io/instance=dynamo-platform -n dynamo-system --timeout=300s
步骤 3:安装 Envoy Gateway
部署启用 ExtensionAPIs 的 Envoy Gateway,以便与 Semantic Router 集成:
# Install Envoy Gateway with custom values
helm install envoy-gateway oci://docker.io/envoyproxy/gateway-helm \
--version v1.3.0 \
--namespace envoy-gateway-system \
--create-namespace \
-f https://raw.githubusercontent.com/vllm-project/semantic-router/refs/heads/main/deploy/kubernetes/dynamo/dynamo-resources/envoy-gateway-values.yaml
# Wait for Envoy Gateway to be ready
kubectl wait --for=condition=Available deployment/envoy-gateway -n envoy-gateway-system --timeout=300s
重要: values 文件启用 extensionApis.enableEnvoyPatchPolicy: true,Semantic Router ExtProc 集成需要此项。
步骤 4:部署 vLLM Semantic Router
使用面向 Dynamo 的配置部署 Semantic Router:
# Install Semantic Router from GHCR OCI registry
helm install semantic-router oci://ghcr.io/vllm-project/charts/semantic-router \
--version v0.0.0-latest \
--namespace vllm-semantic-router-system \
--create-namespace \
-f https://raw.githubusercontent.com/vllm-project/semantic-router/refs/heads/main/deploy/kubernetes/dynamo/semantic-router-values/values.yaml
# Wait for deployment to be ready
kubectl wait --for=condition=Available deployment/semantic-router -n vllm-semantic-router-system --timeout=600s
# Verify deployment status
kubectl get pods -n vllm-semantic-router-system
说明: 该 values 将 Semantic Router 配置为路由到 Dynamo 工作进程提供的 TinyLlama 模型。
步骤 5:部署 RBAC 资源
为 Semantic Router 访问 Dynamo CRD 授予 RBAC:
kubectl apply -f https://raw.githubusercontent.com/vllm-project/semantic-router/refs/heads/main/deploy/kubernetes/dynamo/dynamo-resources/rbac.yaml
步骤 6:部署 Dynamo vLLM 工作进程
使用 Helm Chart 部署 Dynamo 工作进程,可通过 CLI 灵活配置而无需手改 YAML。
选项 A:使用 Helm Chart(推荐)
# Clone the repository (if not already cloned)
git clone https://github.com/vllm-project/semantic-router.git
cd semantic-router
# Basic installation with default TinyLlama model
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system
# Wait for workers to be ready
kubectl wait --for=condition=Available deployment -l app.kubernetes.io/instance=dynamo-vllm -n dynamo-system --timeout=600s
选项 B:通过 CLI 指定自定义模型
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[1].model.path=Qwen/Qwen2-0.5B-Instruct
选项 C:显式 Prefill/Decode
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[0].workerType=prefill \
--set workers[1].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[1].workerType=decode
选项 D:需认证的模型(Llama、Mistral 等)
# Create secret with HuggingFace token
kubectl create secret generic hf-secret \
--from-literal=HF_TOKEN=hf_xxxxxxxxxxxxxxxxxxxx \
-n dynamo-system
# Install with secret reference
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set huggingface.existingSecret=hf-secret \
--set workers[0].model.path=meta-llama/Llama-2-7b-chat-hf \
--set workers[1].model.path=meta-llama/Llama-2-7b-chat-hf
选项 E:自定义 GPU 分配
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set frontend.gpuDevice=0 \
--set workers[0].gpuDevice=1 \
--set workers[0].workerType=prefill \
--set workers[1].gpuDevice=2 \
--set workers[1].workerType=decode
未指定 gpuDevice 时,Chart 使用合理默认:
- Frontend:GPU 0
- Worker 0:GPU 1(index + 1)
- Worker 1:GPU 2(index + 1)
- Worker N:GPU N+1
GPU 0 预留给 Frontend,工作进程依次使用后续 GPU。仅有特定拓扑需求时才需覆盖。
选项 F:合并工作进程模式(非分离)
单工作进程同时处理 Prefill 与 Decode(更简单、GPU 更少):
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[0].workerType=both \
--set workers[0].gpuDevice=1
选项 G:模型调参
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[0].model.maxModelLen=4096 \
--set workers[0].model.gpuMemoryUtilization=0.85 \
--set workers[0].model.enforceEager=true \
--set workers[1].model.path=Qwen/Qwen2-0.5B-Instruct \
--set workers[1].model.maxModelLen=4096 \
--set workers[1].model.gpuMemoryUtilization=0.85 \
--set workers[1].model.enforceEager=true
选项 H:多节点与 nodeSelector
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=meta-llama/Llama-2-7b-chat-hf \
--set workers[0].nodeSelector."kubernetes\.io/hostname"=gpu-node-1 \
--set workers[1].model.path=meta-llama/Llama-2-7b-chat-hf \
--set workers[1].nodeSelector."kubernetes\.io/hostname"=gpu-node-2
选项 I:自定义 CPU/内存
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set workers[0].model.path=meta-llama/Llama-2-7b-chat-hf \
--set workers[0].resources.requests.cpu=4 \
--set workers[0].resources.requests.memory=32Gi \
--set workers[0].resources.limits.cpu=8 \
--set workers[0].resources.limits.memory=64Gi \
--set workers[1].model.path=meta-llama/Llama-2-7b-chat-hf \
--set workers[1].resources.requests.cpu=4 \
--set workers[1].resources.requests.memory=32Gi \
--set workers[1].resources.limits.cpu=8 \
--set workers[1].resources.limits.memory=64Gi
选项 J:使用 Values 文件
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
-f ./deploy/kubernetes/dynamo/helm-chart/examples/values-multi-model.yaml
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
-f ./deploy/kubernetes/dynamo/helm-chart/examples/values-multi-node.yaml
选项 K:Frontend 路由模式
# KV-aware routing (default, recommended)
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set frontend.routerMode=kv
# Round-robin routing
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set frontend.routerMode=round-robin
# Random routing
helm install dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--set frontend.routerMode=random
升级已有部署
# Change model
helm upgrade dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--reuse-values \
--set workers[0].model.path=new-model-name \
--set workers[1].model.path=new-model-name
# Scale replicas
helm upgrade dynamo-vllm ./deploy/kubernetes/dynamo/helm-chart \
--namespace dynamo-system \
--reuse-values \
--set workers[0].replicas=2 \
--set workers[1].replicas=2
验证工作进程
kubectl get pods -n dynamo-system
# Expected output:
# dynamo-vllm-frontend-xxx 1/1 Running
# dynamo-vllm-prefillworker0-xxx 1/1 Running
# dynamo-vllm-decodeworker1-xxx 1/1 Running
Helm Chart 创建:
- Frontend:带 KV 感知路由的 HTTP API(GPU 0)
- prefillworker0:处理 prompt 的 Prefill 工作进程(GPU 1)
- decodeworker1:生成 token 的 Decode 工作进程(GPU 2)
步骤 7:创建 Gateway API 资源
kubectl apply -f https://raw.githubusercontent.com/vllm-project/semantic-router/refs/heads/main/deploy/kubernetes/dynamo/dynamo-resources/gwapi-resources.yaml
# Verify EnvoyPatchPolicy is accepted
kubectl get envoypatchpolicy -n default
重要: EnvoyPatchPolicy 状态须为 Accepted: True。若为 False,请确认 Envoy Gateway 使用了正确的 values 安装。
验证部署
端口转发
# Get the Envoy service name
export ENVOY_SERVICE=$(kubectl get svc -n envoy-gateway-system \
--selector=gateway.envoyproxy.io/owning-gateway-namespace=default,gateway.envoyproxy.io/owning-gateway-name=semantic-router \
-o jsonpath='{.items[0].metadata.name}')
# Port forward to Envoy Gateway (with Semantic Router protection)
kubectl port-forward -n envoy-gateway-system svc/$ENVOY_SERVICE 8080:80 &
# Port forward directly to Dynamo (bypasses Semantic Router)
kubectl port-forward -n dynamo-system svc/dynamo-vllm-frontend 8000:8000 &
