OpenSearch - Connections for Cross-Cluster Search

[arturobayo]

Terraform Version

1.3.0 (latest)

Use Cases

Amazon ElasticSearch/OpenSearch domains (clusters) may connect to other ElasticSearch/OpenSearch domains via "Connections", that are available on AWS API:

https://docs.aws.amazon.com/opensearch-service/latest/developerguide/configuration-api.html

• AcceptInboundConnection
• CreateOutboundConnection
• DeleteInboundConnection
• DescribeInboundConnections
• DescribeOutboundConnections
• RejectInboundConnection

This allows cross-cluster search use cases, for example creating hub-and-spoke search architectures with search clusters distributed across the globe in multiple locations.

Attempted Solutions

1. Use the local-exec provisioner to run a custom script after creating the Domain resource that uses the AWS CLI/API under the hood to create the Connections.

2. Leverage the AWS CloudFormation Stack resource to deploy a custom CloudFormation resource that creates the Connections for the domain.

Proposal

Proposal is to add two new resources to OpenSearch: opensearch_connection and opensearch_connection_accepter

Similar to how Resource Access Manager resource shares work (ram_resource_share and ram_resource_share_accepter)

Hello,

This appears to be a question or an issue with a provider, not with Terraform itself. You can check existing issues and file a new one in the provider's project repository, linked from the their registry page. If you have questions about Terraform or the provider, it's better to use the community forum where there are more people ready to help. The GitHub issues here are monitored only by a few core maintainers.

Thanks!
