Sep 1, 2025September 2025: Delivered meaningful security improvements and CI reliability for the sysdiglabs/charts repository. Implemented Shield Chart documentation updates, security hardening by removing unsafe sysctls in OpenShift SecurityContextConstraints, and a Shield chart version bump. Fixed a critical CI/testing bottleneck by replacing bitnami/kubectl with the Sysdig-provided quay.io/sysdig/sysdig-kubectl across multiple Helm charts. These changes improve security posture, CI consistency, and maintainability, delivering clearer documentation, safer defaults, and more predictable deployments.

Jun 1, 2025June 2025 monthly summary for sysdiglabs/charts focusing on Shield reliability and cluster shield feature enhancements. Key work includes correcting the Shield Chart Collector port to 443 across region-specific templates and tests (affecting Linux and Windows hosts), and introducing a new respond feature mapping in cluster-shield configuration with queue length, timeout, and per-cluster settings. The chart version was bumped and tests updated to reflect these changes. These efforts reduce regional misconfigurations, improve deployment stability, and enhance automated response capabilities for Shield.

Nov 1, 2024November 2024 focused on securing and stabilizing chart deployments in sysdiglabs/charts. Delivered two key features: (1) Kubernetes audit webhook configurability with a new webhook_rules parameter and a cluster-shield bump to v1.5.0; (2) Shield Helm chart stability and enhancements, including reliable values merging, default Kubernetes metadata, clarified configuration options, removal of non-supported cluster_type ('other'), and refined OpenShift host context constraints and host port logic. Tests were updated to reflect these changes. The work reduces operational risk, accelerates secure deployments, and improves upgrade safety. Technologies demonstrated: Kubernetes, Helm, OpenShift, YAML, CI/test automation, and security-focused chart design.
