# dynamo-platform

A Helm chart for NVIDIA Dynamo Platform.

![Version: 0.5.0](https://img.shields.io/badge/Version-0.5.0-informational?style=flat-square) ![Type: application](https://img.shields.io/badge/Type-application-informational?style=flat-square)

## 🚀 Overview

The Dynamo Platform Helm chart deploys the complete Dynamo Cloud infrastructure on Kubernetes, including:

- **Dynamo Operator**: Kubernetes operator for managing Dynamo deployments
- **NATS**: High-performance messaging system for component communication
- **etcd**: Distributed key-value store for operator state management
- **Grove**: Multi-node inference orchestration (optional)
- **Kai Scheduler**: Advanced workload scheduling (optional)

## 📋 Prerequisites

- Kubernetes cluster (v1.20+)
- Helm 3.8+
- Sufficient cluster resources for your deployment scale
- Container registry access (if using private images)
