Lassi Virtanen developed and enhanced Helm chart deployments for the fmidev/helm-charts repository, focusing on scalable, secure Kubernetes provisioning. Over two months, Lassi delivered a robust Deployment Helm Chart for obsapi, implementing Kubernetes Deployments, Services, and ConfigMaps to manage logging and database connectivity with resource controls and environment-specific configurations. He improved deployment reliability by introducing dynamic templating for logging and TNS names, removing hardcoded secrets, and simplifying security contexts. Using YAML and Helm, Lassi also resolved a logging configuration bug, ensuring correct log level determination. His work established reproducible, maintainable infrastructure and accelerated environment parity across development teams.

July 2025: Delivered the initial Deployment Helm Chart for obsapi in fmidev/helm-charts. The chart provisions Kubernetes Deployment, Service, and ConfigMaps for logging and database connection details, with resource requests/limits, image repository/tag, and environment configurations to support reliable, scalable deployments. No major bugs fixed this month. Key results: - Key features delivered: Deployment Helm Chart for obsapi with Kubernetes deployment, service, and config maps for logging and DB connection details; resource management and environment configuration included. - Major bugs fixed: None reported in this period. - Overall impact and accomplishments: Established a reproducible, scalable deployment artifact enabling faster provisioning, standardized environments across dev/stage/prod, and safer rollouts with minimal manual intervention. - Technologies/skills demonstrated: Kubernetes, Helm charts, ConfigMaps, resource management, image tagging/versioning, environment configuration, and version-controlled infrastructure.
