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.
