i have google bigtable cluster created. i'm trying connect following this tutorial trying download cli project , build it, when try execute command fails. tried build simpler example of connector. here is:

computeenginecredentials cannot find metadata server. because code not running on google compute engine.
so mean code can run inside compute engine? there way connect local computer? have examples of this?
for running locally, need make sure environment variable google_application_credentials set key.json got cloud console. cause in case.
