How GitLab CI supported Ticketmaster's ramp up to weekly mobile releases

This post details Ticketmaster's migration from a slow Jenkins CI pipeline to GitLab CI for their Android and iOS mobile releases. Key technical contributions include: configuring GitLab CI to push Docker container images to Amazon ECR and pull them for builds, achieving build/test/artifact generation times under 8 minutes, and integrating Gradle and SonarQube for code quality analysis. The post highlights the challenges with the legacy Jenkins setup (plugin dependency, update difficulties, long build times) and the benefits of GitLab CI (speed, integrated analytics, unified platform).
