Worked on improving the reliability of credential export for OpenSearch in the aws-samples/eks-workshop-v2 repository. Addressed a bug in the AWS Systems Manager parameter retrieval process by refactoring the shell script to remove unnecessary use of tr and adopting jq -r for raw string output. This adjustment ensured that credentials were exported accurately, preventing unintended character stripping and reducing the risk of credential corruption during deployment. Updated related documentation to reflect the new approach. The work demonstrated proficiency in Bash, AWS CLI, and shell scripting, focusing on robust automation and clear documentation to enhance deployment stability and maintainability.
