Worked on the Katello/katello repository to deliver a repository stream upgrade and cleanup, focusing on aligning supported streams with version 6.16. The work involved updating repository configurations to include the latest Capsule, Maintenance, and Utils repositories while removing outdated Client2 repositories for RHEL 7 ELS and other legacy versions. Using JavaScript and full stack development skills, the changes improved consistency across environments, reduced deployment drift, and simplified ongoing maintenance. By ensuring systems pull only the latest supported streams, the update enhanced deployment reliability and security posture, addressing specific issues and streamlining repository management for future releases.
