Web3 Application Stack on K3s Kubernetes — Lightweight, Scalable, Production-Ready 🚀
Designing a reliable Web3 infrastructure doesn’t always require heavyweight clusters. By leveraging K3s, we can build a streamlined, cloud-native blockchain stack optimized for performance, cost, and operational simplicity.
🔐 Secure Access Layer
NGINX Ingress with TLS provides secure entry for Web3 dApps and browsers, ensuring encrypted traffic and centralized routing.
🧠 Indexing & Query Layer
Graph Node exposes GraphQL endpoints for efficient blockchain data indexing and querying, enabling fast subgraph-driven analytics and dApp performance.
📡 RPC Abstraction
An NGINX-based RPC proxy decouples blockchain clients from consumers, supporting JSON-RPC over HTTP and WebSocket for scalable node access.
⛓ Blockchain Execution Layer
Geth runs as a StatefulSet with persistent storage, maintaining blockchain state and enabling reliable synchronization.
🗄 Data Persistence
PostgreSQL stores indexed data with persistent volumes, ensuring durability and high-performance query workloads.
📦 Decentralized Storage
IPFS enables distributed storage of subgraph manifests and metadata, aligning with decentralized architecture principles.
💡 Why K3s for Web3?
• Lightweight Kubernetes distribution
• Lower infrastructure footprint
• Simplified edge & on-prem deployments
