[Terraform provider reference documentation](https://registry.terraform.io/providers/hashicorp/google/latest/docs).

```terraform

  name                             = "example-rmig"
  region                           = "us-east1"
  distribution_policy_zones        = ["us-east1-b", "us-east1-c"]
  distribution_policy_target_shape = "BALANCED"

    minimal_action               = "REFRESH"
    instance_redistribution_type = "NONE"
    max_unavailable_fixed        = 3
  }
  target_size        = 30
