Worked on the kubernetes/website repository to enhance documentation around Pod restart policies and sidecar container behavior. Focused on clarifying restart semantics by introducing a comprehensive comparison table and detailed YAML examples for the Always, OnFailure, and Never policies. Added a dedicated section explaining how sidecar and main containers interact during restarts, with concrete YAML usage examples to illustrate real-world deployment patterns such as Deployments and Jobs. Incorporated reviewer feedback to address documentation issue 51757, improving clarity for new users. The work leveraged Kubernetes expertise, container orchestration knowledge, and technical writing skills, using Markdown and YAML for documentation updates.
