Description

When we've created a Kafka cluster, expose the IPs of the individual brokers as an attribute so that they can be used for other configuration. This is already being exposed by the AWS Go SDK: https://github.com/aws/aws-sdk-go/blob/363ee75f96be07cb7dd905ad9fda37d0eeafeb68/service/kafka/api.go#L2204

Hi, here's some candidate code to use list_nodes to add a new output containing a comma separated list of all ClientVpcIpAddress values for a cluster.

https://github.com/carl34/terraform-provider-aws/blob/msk_list_nodes/website/docs/r/msk_cluster.html.markdown

Example:

output "broker_client_vpc_ip_address" {
  description = "Broker IP Addresses"
  value       " "${aws_msk_cluster.example.broker_client_vpc_ip_addresses}"
}

broker_client_vpc_ip_addresses = 10.0.0.1,10.0.0.2,10.0.0.3

I've run the code successfully, but am still working on unit testing. Please let me know if someone who is familiar with the MSK unit tests can assist.

[WIP] PR created, #12821

Unit test output added to #12821, removed [WIP] from the PR

I think the best solution for this will be a new aws_msk_nodes data source as implemented in #20615.
