I'm testing the "for_each" resource attribute now available in Terraform 12.6 but can't manage to reference created instances in other resources.
azure.tf
variable "customers" {
type = map(object({name=string}))
}
resource "azurerm_storage_account" "provisioning-datalake" {
for_each = var.customers
name = "mydatalake${each.key}"
resource_group_name = "${azurerm_resource_group.provisioning-group.name}"
location = "${azurerm_databricks_workspace.databricks.location}"
account_kind = "StorageV2"
account_tier = "Standard"
account_replication_type = "GRS"
is_hns_enabled = true
enable_advanced_threat_protection = true
tags = {
environment = var.environment
customer = each.value.name
}
}
resource "azurerm_key_vault_secret" "key-vault-datalake-secret" {
for_each = var.customers
name = "mydatalake-shared-key-${each.key}"
value = azurerm_storage_account.provisioning-datalake[each.key].primary_access_key
key_vault_id = azurerm_key_vault.key-vault.id
tags = {
environment = var.environment
customer = each.value.name
}
}
build.tfvars
environment = "Build"
customers = {
dev = {
name = "Development"
},
int = {
name = "Integration"
},
stg = {
name = "Staging"
}
}
I expect "keyvault-datalake-secret" entries to be created with the matching keys of the generated "provisioning-datalake" resources.
But when I run terraform plan --var-file=build.tfvars
, I get the following error:
Error: Invalid index
