Worked on stabilizing upgrade troubleshooting for Kyverno within the giantswarm/handbook repository, focusing on restoring and clarifying documentation to support cluster upgrade resiliency. Addressed upgrade-failure scenarios by reinstating a deleted troubleshooting guide, ensuring operators have access to critical steps for resolving Kyverno stuck-in-pending-upgrade issues. Enhanced the documentation with a rollback path for the security bundle Helm chart, enabling forced re-reconciliation during upgrades and reducing potential fallout. Utilized Markdown and YAML to deliver clear, actionable guidance, while applying Kubernetes expertise to preserve knowledge base integrity. The work emphasized documentation quality, troubleshooting accuracy, and operational continuity for on-call engineering teams.
