  # Hack to ensure ordering of resource creation.
  # This is a homemade `depends_on` https://discuss.hashicorp.com/t/tips-howto-implement-module-depends-on-emulation/2305/2
  # Do not create node_groups before other resources are ready and removes race conditions
  # Ensure these resources are created before "unlocking" the data source.
  # Will be removed in Terraform 0.13
