Worked on the 2gis/on-premise-helm-charts repository to enhance the reliability and security of the Tiles API deployment. Focused on configuration management and DevOps practices, the developer upgraded the Helm chart to version 4.69.0 and introduced a readiness probe using Kubernetes and YAML, ensuring pods were healthy before receiving traffic and reducing startup failures. Additionally, they implemented granular API key management by separating authentication tokens for raster and vector data, updating documentation and proxy configurations to support this change. These improvements strengthened access control and security while streamlining deployment processes for on-premise environments, reflecting a methodical approach to infrastructure reliability.
