Aoshi worked on the eksctl-io/eksctl repository, focusing on backend development and testing using Go. During the month, Aoshi addressed a critical bug in addon version resolution by implementing an exact-match check before partial matching, ensuring that versions with multi-digit suffixes such as v1.7.7-eksbuild.2 and v1.7.7-eksbuild.20 are correctly distinguished. This approach improved the reliability of addon upgrades and reduced the risk of unintended deployments across clusters. Aoshi also expanded unit test coverage to include multi-digit suffix scenarios, strengthening regression protection and stabilizing the version management workflow for eksctl’s addon upgrade process.
