        Error: Duplicate provider configuration

          on terraform_plugin_test.tf line 2:

        A default (non-aliased) provider configuration for "kubectl" was already
        given at terraform_plugin_test.tf:1,1-19. If multiple configurations are
        required, set the "alias" argument for alternative configurations.
