PROFILE
Mattia
Mattia contributed to the cozystack/cozystack repository by enabling secure, multi-tenant SSH access to KubeVirt VMs through RBAC-based port forwarding, using YAML to define precise access controls. He implemented least-privilege RBAC rules for virtualmachineinstances/portforward, allowing authorized SSH tunnels via virtctl while minimizing exposure and supporting operational efficiency. In a later phase, Mattia improved reliability and observability by aligning CoreDNS RBAC permissions and correcting a PromQL syntax error in monitoring alerts. His work leveraged Kubernetes, Prometheus, and Helm, resulting in more stable DNS resolution and alerting, and demonstrated a strong grasp of cloud infrastructure and DevOps best practices.

Feb 1, 2026February 2026 monthly summary for cozystack/cozystack. This period focused on reliability and observability improvements in the DNS stack and monitoring alerts. Key deliverables reduced operational risk by aligning CoreDNS with Kubernetes RBAC and fixing a PromQL syntax error in CNPGClusterOffline alert, leading to more stable pod behavior and fewer alert-related disruptions. Technologies demonstrated include Kubernetes RBAC and ServiceAccounts, CoreDNS deployment via Helm charts, Prometheus/VMA (vmalert) query correctness, and solid Git-based change provenance.
