PROFILE
Mario Manno
Over five months, Michael Manno engineered robust infrastructure and deployment solutions across the rancher/fleet and rancher/dartboard repositories. He enhanced CI/CD reliability by migrating workflows to standalone GitHub Actions runners, improving isolation and resource control. In rancher/fleet, he refined the Helm deployer’s service account impersonation logic and clarified documentation, reducing deployment errors for Kubernetes operators. Michael also improved the GitOps CLI user experience and test suite maintainability using Go and YAML. On rancher/dartboard, he advanced large-scale AWS fleet provisioning with Terraform and Shell, optimizing network scalability and ARM64 compatibility. His work demonstrated depth in DevOps, cloud infrastructure, and end-to-end testing.

Jul 1, 2025For 2025-07, three core deliverables for rancher/dartboard focused on reliability, scalability, and documentation. Implemented RKE2 installation sourcing artifacts from a prime Rancher internal registry with a local artifact path, eliminating Docker Hub dependency and improving reliability. Expanded AWS subnet CIDR sizes and tuned ARP cache and inotify limits to support larger deployments and K3s vcluster scenarios, with new sysctl config applied. Authored and published a comprehensive documentation guide for provisioning a 5000 K3k vCluster fleet, detailing AWS requirements, Dartboard modifications, and step-by-step configuration for K3k, Fleet, and agent registration.
