# Dynamo Kubernetes Platform

Deploy and manage Dynamo inference graphs on Kubernetes with automated orchestration and scaling, using the Dynamo Kubernetes Platform.

## Quick Start Paths

**Path A: Production Install**
Install from published artifacts on your existing cluster → [Jump to Path A](#path-a-production-install)

**Path B: Local Development**
Set up Minikube first → [Minikube Setup](minikube.md) → Then follow Path A

**Path C: Custom Development**
Build from source for customization → [Jump to Path C](#path-c-custom-development)

## Prerequisites

```bash
# Required tools
kubectl version --client  # v1.24+
helm version             # v3.0+
docker version           # Running daemon

# Set your inference runtime image
export DYNAMO_IMAGE=nvcr.io/nvidia/ai-dynamo/vllm-runtime:0.5.0
# Also available: sglang-runtime, tensorrtllm-runtime
```

> [!TIP]
> No cluster? See [Minikube Setup](minikube.md) for local development.

## Path A: Production Install

Install from [NGC published artifacts](https://catalog.ngc.nvidia.com/orgs/nvidia/teams/ai-dynamo/collections/ai-dynamo/artifacts) in 3 steps.

```bash
# 1. Set environment
export NAMESPACE=dynamo-kubernetes
export RELEASE_VERSION=0.5.0 # any version of Dynamo 0.3.2+

# 2. Install CRDs
helm fetch https://helm.ngc.nvidia.com/nvidia/ai-dynamo/charts/dynamo-crds-${RELEASE_VERSION}.tgz
helm install dynamo-crds dynamo-crds-${RELEASE_VERSION}.tgz --namespace default

# 3. Install Platform
kubectl create namespace ${NAMESPACE}
helm fetch https://helm.ngc.nvidia.com/nvidia/ai-dynamo/charts/dynamo-platform-${RELEASE_VERSION}.tgz
helm install dynamo-platform dynamo-platform-${RELEASE_VERSION}.tgz --namespace ${NAMESPACE}
```

> [!TIP]
> By default, Grove and Kai Scheduler are NOT installed. You can enable them by setting the following flags in the helm install command:

```bash
--set "grove.enabled=true"
--set "kai-scheduler.enabled=true"
```

## Path C: Custom Development

Build and deploy from source for customization.

### Quick Deploy Script

```bash
# 1. Set environment
export NAMESPACE=dynamo-cloud
export DOCKER_SERVER=nvcr.io/nvidia/ai-dynamo/  # or your registry
export DOCKER_USERNAME='$oauthtoken'
export DOCKER_PASSWORD=<YOUR_NGC_CLI_API_KEY>
export IMAGE_TAG=0.5.0

# 2. Build operator
cd deploy/cloud/operator
earthly --push +docker --DOCKER_SERVER=$DOCKER_SERVER --IMAGE_TAG=$IMAGE_TAG
cd -

# 3. Create namespace and secrets
kubectl create namespace ${NAMESPACE}
kubectl create secret docker-registry docker-imagepullsecret \
  --docker-server=${DOCKER_SERVER} \
  --docker-username=${DOCKER_USERNAME} \
  --docker-password=${DOCKER_PASSWORD} \
  --namespace=${NAMESPACE}

# 4. Deploy
helm repo add bitnami https://charts.bitnami.com/bitnami
./deploy.sh --crds
```

### Manual Steps (Alternative)

<details>
<summary>Click to expand manual installation steps</summary>

**Step 1: Install CRDs**
```bash
helm install dynamo-crds ./crds/ --namespace default
```

**Step 2: Install Platform**
```bash
helm dep build ./platform/
helm install dynamo-platform ./platform/ \
  --namespace ${NAMESPACE} \
  --set "dynamo-operator.controllerManager.manager.image.repository=${DOCKER_SERVER}/dynamo-operator" \
  --set "dynamo-operator.controllerManager.manager.image.tag=${IMAGE_TAG}" \
  --set "dynamo-operator.imagePullSecrets[0].name=docker-imagepullsecret"
```
</details>

→ [Verify Installation](#verify-installation)

## Verify Installation

```bash
# Check CRDs
kubectl get crd | grep dynamo

# Check operator and platform pods
kubectl get pods -n ${NAMESPACE}
# Expected: dynamo-operator-* and etcd-* pods Running
```

## Next Steps

1. **Deploy Model/Workflow**
   ```bash
   # Example: Deploy a vLLM workflow with Qwen3-0.6B using aggregated serving
   kubectl apply -f components/backends/vllm/deploy/agg.yaml -n ${NAMESPACE}

   # Port forward and test
   kubectl port-forward svc/agg-vllm-frontend 8000:8000 -n ${NAMESPACE}
   curl http://localhost:8000/v1/models
   ```

2. **Explore Backend Guides**
   - [vLLM Deployments](../../../components/backends/vllm/deploy/README.md)
   - [SGLang Deployments](../../../components/backends/sglang/deploy/README.md)
   - [TensorRT-LLM Deployments](../../../components/backends/trtllm/deploy/README.md)

3. **Optional:**
   - [Set up Prometheus & Grafana](metrics.md)
   - [SLA Planner Deployment Guide](sla_planner_deployment.md) (for advanced SLA-aware scheduling and autoscaling)

## Troubleshooting

**Pods not starting?**
```bash
kubectl describe pod <pod-name> -n ${NAMESPACE}
kubectl logs <pod-name> -n ${NAMESPACE}
```

**HuggingFace model access?**
```bash
kubectl create secret generic hf-token-secret \
  --from-literal=HF_TOKEN=${HF_TOKEN} \
  -n ${NAMESPACE}
```

**Clean uninstall?**
```bash
./uninstall.sh  # Removes all CRDs and platform
```
