Worked on the elastic/cloud-on-k8s repository to improve the reliability of Elasticsearch snapshot backups using S3 by addressing documentation accuracy. Focused on aligning the secretName in the snapshot manifest example with the actual secret used for the custom truststore, this update reduced the risk of misconfiguration in production environments. The contribution involved a targeted documentation fix using asciidoc, ensuring that users referencing the backup configuration receive correct and actionable guidance. By prioritizing clear and precise documentation, the work helped prevent potential support issues and streamlined the setup process for backup reliability, demonstrating attention to detail and expertise in documentation practices.
