I am trying to create multiple service bus topics with different subscriptions in azure using terraform.
locals {
servicebus = {
"topic_1" = [{
subscription = ["subscription1", "subscription2", "subscription3"]
}],
"topic_2" = [{
subscription = ["subscription4", "subscription5", "subscription6"]
}],
“topic_3” = [{
subscription = ["subscription7", "subscription8", "subscription9"]
}]
}
service_bus = merge([
for topicname, topic in local.servicebus : {
for subname in topic[0].subscription :
"${topicname}-${subname}" => {
name = topicname
subscription_name = subname
}
}
]…)
}
resource “azurerm_resource_group” “rg” {
name = “demo”
location = “eastus2”
}
