Web3 NFT Marketplace Infrastructure: Multi-Environment EKS with Blockchain Node Automation and Secrets Management

Why This Matters

These results demonstrate the tangible business value of investing in the right technology infrastructure — from improved reliability to measurable cost savings.

Owens's Challenge

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

Implementation Details

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
