Add reader connection endpoint for aws_elasticache_replication_group #23691

Closed Shivang44 closed 4 years ago

Shivang44 commented 4 years ago

Current Terraform Version

Terraform v0.12.13

Use-cases

When creating an elasticache redis cluster (with cluster mode disabled) you get a "primary" endpoint and a read-only "reader" endpoint. The aws_elasticache_replication_group doesn't output the reader endpoint, despite this information being displayed (both the primary and reader) when you click the redis cluster in AWS: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Endpoints.html

Attempted Solutions

A workaround right now is to replace the word "master" in the primary endpoint with "replica". However this seems brittle as AWS could change their naming scheme. It would be nice to use the Reader URL returned directly in the AWS response.

Proposal

add reader_endpoint_address to the output of aws_elasticache_replication_group
