Description

Add support of BigTable cluster autoscaling_config for google_bigtable_instance resource. We want to add policy to control the max_nodes in autoscaling of BigTable.
Is there any other way to read the terraform state json directly? so we can use that until this support is added.

Affected Resource(s)

• https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/bigtable_instance

Resource converter exists?

No

gcloud terraform vet supports Terraform-based constraints: https://cloud.google.com/docs/terraform/policy-validation/create-terraform-constraints

@melinath I tried with gcloud beta terraform vet, but same issue, I am not able to access autoscaling_config. Even though its available in tfplan.json.
I can see only location, serverNodes, defaultStorageType, name when I print input.review which is supported https://github.com/GoogleCloudPlatform/terraform-validator/blob/main/converters/google/resources/bigtable_cluster.go#L65

Is that mean as of now there is no way to access autoscaling_config, with out adding them in https://github.com/GoogleCloudPlatform/terraform-validator/blob/main/converters/google/resources/bigtable_cluster.go#L65?

The support for Terraform resources in gcloud terraform vet doesn't go through Terraform Validator - it just passes the resource change data directly from your plan file to the validation framework.
