Worked on the crossoverJie/starrocks repository to enhance the security posture of the Iceberg quickstart documentation by disabling AWS EC2 metadata service usage. This change, implemented using Markdown and grounded in cloud security best practices, aimed to minimize the risk of metadata exposure and strengthen defense-in-depth for users following the quickstart guide. The update was developed collaboratively, adhering to contributor guidelines and version-control standards, and received multi-author review and sign-off. The work demonstrated a focus on documentation-driven security hardening, ensuring that the repository’s onboarding materials align with evolving security standards and reduce the potential data surface for new deployments.
