Opensearch as Search Engine Deployment with AWS IAM Authentication

[jz-xie]

Ask shown in the document here

Seems like only user and password is supported for Opensearch. It would be useful to have AWS IAM authentication supported as well.

Hi @Prajwal214

Does the IAM auth also works for OpenSearch?

My AWS Opensearch only have IAM and Cognito authentication. I was unable to connect with opensearch using either method.
Is there a way to authenticate Opensearch using any of these approachs?

There is tool might be useful for you:

https://github.com/awslabs/aws-sigv4-proxy

You can try deploy this tool as a sidecar container of OpenMetadata to sign its OpenSearch requests, with you AWS IAM role attached in service account.

I have not deployed it myself because the latest version has a critical vulnerability that would not pass my security check.

Sharing a working solution in EKS deployment:

Attach the application service account with a AWS IAM role that has access your AWS OpenSearch instance, config your helm values like the following

openmetadata:
  config:
    elasticsearch:
      enabled: true
      host: localhost
      searchType: opensearch
      port: 8080
      scheme: http
      connectionTimeoutSecs: 5
      socketTimeoutSecs: 60
      keepAliveTimeoutSecs: 600
      batchSize: 10
      auth:
        enabled: false
