May 2025 monthly summary for opensupplyhub/open-supply-hub focused on expanding deployment capabilities, hardening security, and improving CI/CD reliability to drive faster, safer releases and broader environment support. Key outcomes include: - Deployed RBA environment support by updating CI/CD pipelines and Terraform configurations, disabled CSV export in RBA, and fixed a frontend environment check to ensure correct environment handling. - Simplified AWS deployment workflow by removing an unnecessary tag check and eliminating a None assignment to the deploy-env variable, ensuring deployments always target a defined environment. - Tightened security and governance by removing a deprecated CORS origin (a.os-hub.net), reducing attack surface and potential misconfigurations in CORS settings. Business value: - Expanded deployment scenarios (RBA) enable new environments and customers with safer, more predictable deployments. - Reduced risk and operational overhead through streamlined CI/CD and robust environment handling. - Improved security posture and compliance by removing obsolete origins from allowed CORS origins. Technologies/skills demonstrated: - Django CORS configuration and origin management - GitHub Actions-based CI/CD; Terraform-based infrastructure updates - Frontend environment checks and release workflow integration - Terraform and deployment pipeline governance
