Jan 1, 2026January 2026 monthly summary for CruGlobal/mobile-content-api focused on deployment readiness, build efficiency, and dev experience improvements. Implemented Dockerfile and deployment configuration enhancements to support Redis-backed sessions/storage, AWS region/bucket configuration for the mobile content API, and external service integrations (Salesforce, Apple, Okta, Facebook). Consolidated asset compilation with DB creation/docs generation to speed builds and reduce cycle times. Updated the documentation generation command to improve maintainability and accessibility of build docs. Cleaned development tooling by removing rubocop-rails-omakase from the Gemfile to simplify the development environment. Fixed arg value handling in Dockerfile to ensure correct deployment configuration, improving reliability. Overall, these changes deliver a more configurable, faster, and more maintainable CI/CD pipeline with broader external service support and a simpler local development workflow.

May 1, 2025May 2025 – CruGlobal/mobile-content-api Key accomplishments: - Upgraded Ruby runtime to 3.2.8, refreshed gem dependencies for compatibility, and adjusted Datadog configuration to improve observability and monitoring. - Stabilized build environment by adding YAML development headers (yaml-dev) in the Dockerfile to ensure gems compile cleanly during image builds. - Implemented Ruby 3.2+ compatibility fixes: replaced File.exists? with File.exist? and adjusted related logic, alongside Brakeman scanner configuration updates to reflect dependency changes (minor version bump). - Commits of record: 09a02c07399e6a00094e5b748f911589a02073ca (Upgrade to Ruby 3.2.8); 1c181d31938d8a14315a99ef755954755947414a (Add yaml-dev during build process); 20a3839d1e9240a8b5bf7d47bd81c4f54c06c39c (Add File monkeypatch). Impact: - Improved deployment reliability and runtime stability on Ruby 3.2+, reducing risk of gem install failures and runtime incompatibilities. - Enhanced security scanning and configuration accuracy with Brakeman updates. - Better observability and operational readiness through Datadog integration improvements. Technologies/skills demonstrated: - Ruby 3.2, Docker build optimization (yaml-dev), Datadog integration, Brakeman scanner configuration, and Ruby monkeypatch techniques.
