Web3 NFT Marketplace Infrastructure: Multi-Environment EKS with Blockchain Node Automation and Secrets Management
Built Owens.market NFT platform on multi-environment EKS with AWS Secrets Manager CSI, Terraform + Ansible for Antelope blockchain nodes, and GitHub Actions CI/CD.
Key Results
Production, testing, and load testing on EKS
All credentials via Secrets Manager CSI
Terraform + Ansible for blockchain nodes
Rolling updates with rollback capability
What We Were Solving
Owens was building a Web3 NFT marketplace combining traditional cloud infrastructure with blockchain networks and AI-powered NFT generation. This hybrid architecture presented unique DevOps challenges spanning multiple technology domains.
Infrastructure complexity:
- Multi-environment isolation needed — production, testing, and load testing environments for a high-value NFT platform
- Antelope blockchain nodes required automated provisioning and deployment with specific configurations
- Sensitive credentials (database passwords, API keys, encryption keys) needed secure injection without storing in Git repositories
- DALL-E and GPT integration for AI-generated NFTs required reliable infrastructure with proper rate limiting and cost controls
- Smart contract deployment coordination between blockchain nodes and marketplace backend
How We Solved It
We designed a comprehensive Web3 infrastructure combining Kubernetes for the marketplace platform, Terraform for blockchain node automation, and enterprise-grade secrets management.
Multi-Environment EKS Platform
Built isolated Kubernetes namespaces for production, testing, and load testing with environment-specific configurations, resource quotas, and network policies preventing cross-environment access.
Secrets Management
- Implemented AWS Secrets Manager CSI driver for runtime injection of credentials directly into pods
- Secrets never stored in Kubernetes etcd — fetched on-demand from AWS Secrets Manager
- Automatic secret rotation without pod restarts using CSI driver sync
Blockchain Node Automation
- Terraform modules for Antelope blockchain node provisioning with VPC, security groups, and EC2 instances
- Ansible playbooks for blockchain software installation and configuration management
CI/CD & Testing
- GitHub Actions pipeline with Docker builds, ECR pushes, and rolling EKS deployments
- Locust-based load testing for marketplace APIs including fee calculations and vault operations
Technologies Used
“Building a Web3 platform requires bridging traditional cloud infrastructure with blockchain networks. QuantaCodes understood both worlds and delivered an infrastructure that scales with our marketplace while keeping our secrets secure and our deployments reliable.”
