Automated deployment and management system for 20+ blockchain validator nodes
Production-grade automation toolkit for deploying blockchain validator infrastructure. Reduced deployment time from 2+ hours to under 5 minutes with zero-downtime updates and automated health checks.
Managed Infrastructure: 20+ nodes across protocols including Nexus, Nillion, Ocean Protocol, Ink, Nesa, and Network3.
- One-Command Deployment - Automated installation with dependency resolution
- Port Conflict Prevention - Pre-flight checks before deployment
- Interactive CLI - Menu-driven interface for all node operations
- Docker Orchestration - Multi-container coordination with health checks
- Zero-Downtime Updates - Rolling updates with automated rollback
- Secure Key Management - Hidden private key input and credential handling
- Real-Time Monitoring - Log streaming and sync status checks
- Infrastructure: Docker, Docker Compose, systemd, GNU screen
- Scripting: Bash automation with error handling
- Networking: Custom RPC configurations, P2P networking, WebSocket endpoints
- Tools: Git, curl, jq, protobuf, Rust toolchain
