Worked on enhancing operator-facing documentation for RKE2 networking requirements in the rancher/rke2-docs repository. Focused on clarifying that ports 6443 and 9345 must be open across all RKE2 nodes, not just agent nodes, and updated the requirements table to accurately reflect source and destination details. Improved network configuration guidance to help reduce cluster setup errors and ensure smoother deployments. The work was delivered as a targeted documentation update using Markdown, leveraging skills in technical writing and networking. All changes were tracked for traceability and review, contributing to more reliable and accessible documentation for RKE2 cluster administrators.
