Hi Ashish, can you try connecting Pega SRS to AWS OpenSearch using IAM role-based authentication, your only solution is to manually force the required ServiceAccount annotations during your deployment process. First, you must update your Helm values file by setting your specific AWS region under the srs.srsStorage.awsIAM.region parameter, which activates the required IAM authentication protocol within the SRS application. Next, because the chart lacks a native values block for identity tags, you must apply a custom patch during your Helm deployment to inject the eks.amazonaws.com/role-arn annotation directly into the generated SRS Kubernetes ServiceAccount. The underlying SRS Docker image fully supports standard AWS credentials, so forcefully attaching this role annotation ensures EKS automatically grants your pod the exact identity needed to securely access OpenSearch.
