Description

One or more AWS attribute best practices are not followed for this Databricks cluster.

The rule flags databricks_cluster resources when:

  • aws_attributes.availability is set to SPOT
  • aws_attributes.first_on_demand is missing or set to 0
  • aws_attributes.zone_id is not equal to auto

Each finding includes documentId, resourceType, resourceName, searchKey, issueType, keyExpectedValue, and keyActualValue.

Compliant Code Examples

resource "databricks_cluster" "negative" {
  cluster_name            = "Shared Autoscaling"
  spark_version           = data.databricks_spark_version.latest.id
  node_type_id            = data.databricks_node_type.smallest.id
  autotermination_minutes = 20
  autoscale {
    min_workers = 1
    max_workers = 50
  }
  aws_attributes {
    availability           = "SPOT_WITH_FALLBACK"
    zone_id                = "auto"
    first_on_demand        = 1
    spot_bid_price_percent = 100
  }
