From 353068222a3fa4c0247233a8ab938dd5dabf2c1e Mon Sep 17 00:00:00 2001 From: "Bot (Matt McCarthy)" Date: Wed, 6 May 2026 09:55:40 -0500 Subject: [PATCH] feat: implement CI/CD pipeline with GitHub Actions and AWS Lambda Replace manual EC2 deployment with structured serverless infrastructure: - GitHub Actions workflow for automated testing, building, and deployment - AWS Lambda functions for staging and production environments - Environment-specific configuration files (dev/staging/prod) - AWS SAM CloudFormation template for infrastructure-as-code - DevOps test suite for infrastructure validation - Smoke tests for deployed environment health checks - Comprehensive deployment documentation This implementation addresses all requirements from issue #7: 1. Build release images outside production (in CI pipeline) 2. Decouple from EC2 to serverless architecture (AWS Lambda) 3. Implement DevOps test suite (pytest-based infrastructure tests) 4. Define GitHub Actions pipeline with staging/production stages 5. Clearly define environment variables for each stage 6.

+✅ **Separation of Concerns**: Development, staging, and production are isolated environments +✅ **Infrastructure as Code**: All infrastructure defined in version-controlled YAML +✅ **Automated Testing**: Tests run automatically on every commit +✅ **Staged Deployments**: Changes validated in staging before production +✅ **Audit Trail**: All deployments tracked in GitHub Actions and AWS +✅ **Secrets Management**: Sensitive data in GitHub Secrets, never in code +✅ **Rollback Capability**: Easy rollback to previous versions +✅ **Monitoring**: CloudWatch metrics and alarms for observability + +## Related Issues + +- Issue #1: CSP Whitelist for Inline Scripts - Uses this infrastructure for deployment +- Related documentation: See AWS SAM, GitHub Actions, and serverless best
