Can we data refer to eventhub instances through eventhub namespaces in Terraform?

Question

I have question around azurerm eventhub. Right now I am data referring to Eventhub namespace but I am unable to get the instances in the output!

data "azurerm_eventhub_namespace" "eventhub_namespace" {
  name  ="example"
  resource_group_name = "example resource group"
}

but do we have something like

data "azurerm_eventhub_instance" "eventhub_instace" {
  name_instance  ="example"
  resource_group_name = "example resource group"
}

What do you mean by instance? You mean eventhubs under the namespace? — Serkant Karaca, Feb 03 '20 at 19:21
Yes to be precise I want to data refer the Eventhub's under the Eventhub namespace's and use them for IoT hub routes — adesh REDDY, Feb 03 '20 at 19:27

Unfortunately, I'm afraid you cannot do that. Terraform only expose azurerm_eventhub_instance in the data source. So what you want does not support by Terraform.

The possible solution is that you can use the external data source to execute the script, and then use the script to get the instance in the namespace.

I came up with these small script to grab con string's.

#!/usr/bin/env bash
RG=$1
EVENTHUBNAMESPACE=$2
SUBSCRIPTION=$3
az eventhubs eventhub list --resource-group "$RG" --namespace-name "$EVENTHUBNAMESPACE" --subscription "$SUBSCRIPTION" > eventhub.json
eventhub=( $(jq -r '.[].name' eventhub.json) )
for eventhub in "${eventhub[@]}"; do
 az eventhubs eventhub authorization-rule keys list --resource-group "$RG"  --namespace-name "$EVENTHUBNAMESPACE" --eventhub-name "$eventhub" --name "$eventhub" --subscription "$SUBSCRIPTION" > eventhubcon.json
 arr=( $(jq -r '.primaryConnectionString' eventhubcon.json) )
  for constr in "${arr[@]}"; do
  printf '%s\n' "${arr[@]}"
  done
done

This is not the answer to the question you asked, although it's another direction of the solution. I think my answer answered your question correctly. — Charles Xu, Feb 05 '20 at 01:34
