Debug Output

Panic Output

Expected Behavior

default_labels are applied to google_sql_database_instance.

Actual Behavior

Resource does not get any labels. Probably because the argument for google_sql_database_instance is named user_labels.

Steps to Reproduce

1. terraform apply

Important Factoids

References

• Code where default_labels are applied: https://github.com/GoogleCloudPlatform/magic-modules/blob/main/mmv1/third_party/terraform/tpgresource/labels.go#L58

  Looks to me like it skips this if there is no labels argument.

The default_labels is not going to be applied to google_sql_database_instance resource as user_labels is nested inside settings and there is a bug in terraform sdk that SetNew is not working in the nested fields. It needs to wait until the resource is migrated to plugin framework.

The default_labels will be available in the data source google_client_config (https://github.com/hashicorp/terraform-provider-google/issues/19140)
