Andrey Kazakov developed and deployed a custom Tiles API solution, tilegen, for on-premise clusters using Helm in the 2gis/on-premise-helm-charts repository. He engineered a comprehensive Kubernetes deployment, incorporating CronJobs, Deployments, Jobs, ConfigMaps, Secrets, and Services, and introduced a health check endpoint to ensure reliable operation. His work emphasized configurability, enabling dynamic image tagging and customizable tileset names through YAML and Helm templating. Andrey also refined documentation in Markdown and improved onboarding by standardizing deployment processes. The result was a robust, maintainable deployment pipeline that streamlined upgrades and facilitated on-demand, configurable tile generation for enterprise Kubernetes environments.
