Developed a comprehensive TLS Migration Documentation Guide for the etcd-io/website repository, focusing on helping users transition existing non-TLS etcd clusters to secure TLS configurations for both client-to-server and server-to-server communication. The work involved creating detailed, step-by-step instructions using Markdown, covering cluster status checks, certificate preparation, TLS enablement, and post-migration verification. Emphasizing DevOps and security best practices, the guide provides a reusable documentation pattern that reduces migration risks and streamlines onboarding for secure deployments. This contribution enhanced the clarity and accessibility of security-focused documentation, supporting users in implementing robust TLS configurations with practical, actionable guidance.
