PROFILE
Shashank Wagle K
Over seven months, contributed to Siemens-Healthineers/K2s by engineering robust CI/CD and containerization workflows, focusing on addon export/import, logging, and deployment automation. Developed OCI-compliant packaging and GitOps-based deployment using Go, PowerShell, and YAML, enabling seamless integration with tools like Argo CD and Flux CD. Enhanced logging infrastructure with Fluent Bit and OpenSearch, supporting both Linux and Windows environments, and improved reliability through refined error handling and resource optimization. Delivered modular features such as Windows Exporter and streamlined KEDA configuration, while strengthening documentation and testing. These efforts improved deployment stability, observability, and maintainability across diverse cloud and on-premises environments.

Apr 1, 2026April 2026 — Siemens-Healthineers/K2s: Delivered a robust Fluent Bit logging addon with optional OpenSearch deployment and Windows logging integration, delivering end-to-end observability while controlling costs. Key deliveries include: (1) Fluent Bit deployment with --omitOpensearch flag; updated manifests and documentation; added end-to-end tests to verify Fluent Bit deployment with and without OpenSearch. (2) Reliability enhancements: separated readiness checks into a dedicated function, extended DaemonSet rollout timeouts, updated Windows image and configuration, and improved error handling in PowerShell scripts. (3) Quality and maintainability: added new stdout ConfigMaps for Linux and Windows, refactored error handling and readiness logic, and updated visibility through docs. (4) Testing and compatibility: updated tests for omitOpenSearch path; attempted Fluent Bit upgrade to 5.0.3 with a rollback to maintain stability and compatibility. (5) Cross-cutting improvements: kernel/WSL2 compatibility fixes (kernel grep), and ongoing documentation improvements. Business value and impact: enhanced cross-platform log collection and observability, reduced OpenSearch footprint when not required, more reliable deployments, faster troubleshooting, and clearer operational guidelines for the logging stack. Technologies demonstrated: Fluent Bit, OpenSearch (optional), Windows/Linux logging, Kubernetes (DaemonSets, ConfigMaps), Dockerfiles, PowerShell automation (Get-Status.ps1, Update.ps1, Enable.ps1), e2e testing, and YAML/Manifest management.

Nov 1, 2025November 2025: Siemens-Healthineers/K2s delivered three core features, stabilized cross-OS export workflows, and reduced maintenance overhead. Key features: 1) Addon Image Management via YAML manifests (flexible external YAML-specified addon images; improved extraction and path resolution). 2) Windows Exporter modular deployment and export workflow (on-demand component; improved Windows image export reliability; cross-OS handling). 3) KEDA configuration simplification (simplified YAML naming; aligns with latest docs). Major bugs fixed: - Fixed path resolution of additional images in addons manifest; - Fixed exporting Windows-Exporter image as a tar during offline export; - Fixed Windows-exporter image pull via nerdctl/crictl; - Reverted experimental Windows/Linux export loop due to stability). Overall impact: enhanced reliability and maintainability; on-demand Windows monitoring; more predictable multi-OS image exports; improved image management. Technologies demonstrated: YAML manifests, image extraction/path resolution, tar exports, nerdctl/crictl, on-demand deployment patterns, cross-OS export orchestration.

Oct 1, 2025October 2025 focused on delivering a CD-ready addon packaging workflow for Siemens-Healthineers/K2s. Delivered a CD-compatible Addon Export/Import with Versioned Archives and Metadata, enabling Argo CD-style deployment of addons. Implemented versioned zip naming and added a version.info file within each addon's content to carry CD-friendly metadata. Refined import manifest handling to correctly merge multiple implementations and excluded tar files during import. Implemented processing/removal of version.info files as part of the workflow to keep artifacts clean. A critical fix: Make addon zip content usable by CD solutions like Argo CD (commit c39891b0b95e2c9e39f533192a457fd66489b0d8), resolving deployment blockers and improving automation reliability.
