KDV

Kubernetes Dependency Viewer (KDV)

KDV (Kubernetes Dependency Viewer) is an open-source tool designed to visualize the relationships and dependencies between various Kubernetes resources within a cluster. It provides an intuitive, interactive graph interface to help developers and DevOps engineers understand how workloads, services, configurations, and storage are connected.

Features

• Interactive Graph Visualization: Uses React Flow to render clear, interactive dependency graphs.
• Namespace Filtering: Easily switch between namespaces to focus on specific environments.
• Resource Relationships: Visualizes connections such as:
  • Deployment/StatefulSet/DaemonSet ➡️ Pod
  • Service ➡️ Pod
  • Ingress ➡️ Service
  • Pod ➡️ ConfigMap, Secret, PersistentVolumeClaim
  • PersistentVolumeClaim ➡️ PersistentVolume
  • CronJob ➡️ Job ➡️ Pod
• Zero Configuration: Automatically reads your ~/.kube/config when run locally or uses the ServiceAccount token when running in-cluster.
• Single Container Deployment: Backend (FastAPI) and Frontend (React/Vite) are bundled together for easy deployment.

Technology Stack

• Backend: Python 3.12, FastAPI, Kubernetes Python Client
• Frontend: TypeScript, React 18, Vite, React Flow, Zustand, TanStack Query
• Deployment: Docker, Docker Compose, Helm
• CI/CD: GitHub Actions (Linting, Docker Build & Push, Releases)

Quick Start (Local with Docker Compose)

To run KDV locally using your existing ~/.kube/config:

# Clone the repository
git clone https://github.com/AlexPokatilov/KDV.git
cd KDV

# Run with docker-compose
docker compose up -d

Open your browser and navigate to http://localhost:8000.

Kubernetes Deployment (Helm)

# Add the Helm repository
helm repo add kdv https://alexpokatilov.github.io/KDV
helm repo update

# Install the chart
helm install kdv kdv/kdv --namespace kdv --create-namespace

Important Helm Configuration (values.yaml)

By default, the Helm chart creates a Role and RoleBinding to allow KDV to read resources only in the namespace it is deployed to.

If you want KDV to view resources across the entire cluster, enable cluster-scoped RBAC:

rbac:
  create: true
  clusterScoped: true
