Attach a databricks_instance_pool to databricks_cluster_policy via terraform

[mannepk85]

Hello Team,

I am trying to create a databricks instance pool and attach it to a cluster policy in our terraform code. But I am having hard time finding a good documentation. Has any one done it? Below is my sample code and I am getting error

I keep getting error in Databricks UI "Invalid JSON". Json is valid. Is it even possible to attach the instance pool at cluster policy level or should it be done at cluster level only?

resource "databricks_instance_pool" "dev_test_cluster_pool" {
  instance_pool_name                    = "dev_test_cluster_pool-small"
  provider                              = databricks.workspace-development
  idle_instance_autotermination_minutes = 10
  min_idle_instances                    = 1
  node_type_id                          = m6gd.large
  aws_attributes {
    availability           = "ON_DEMAND"
    spot_bid_price_percent = "100"
  }
}

resource "databricks_cluster_policy" "dev_test_policy" {
  provider = databricks.workspace-development
  name     = "app.databricks.dev.test.app.policy"
  ........ # removed other attributes
  "instance_pool_id":databricks_instance_pool.dev_test_cluster_pool.id
  description = "this Policy is managed by terraform and created for testing pools"
  
}

Fixed it! 

"instance_pool_id" : {
  type   = "fixed"
  values = "databricks_instance_pool.dev_test_cluster_pool.id"
}
