Tensorboard Unavailable: Error executing an HTTP request: libcurl code 6

When I try to run tensorboard with a logdir in google cloud storage I get the following error (with various retry attempts):

Error executing an HTTP request: libcurl code 6 meaning 'Couldn't
resolve host name', error details: Couldn't resolve host 'metadata'

I have previously run gcloud auth and can be confident that I am authenticated correctly because I can read from the given logdir by running

gcloud auth

gsutil ls gs://path/to/logdir


which works as expected.

Any idea how to proceed so that I can run tensorboard against this logdir?

This was happening because the GOOGLE_APPLICATION_CREDENTIALS environment variable was not set.

GOOGLE_APPLICATION_CREDENTIALS

Seems that gsutil was authenticated ok with the gcloud auth ... command but that tensorboard also needed the GOOGLE_APPLICATION_CREDENTIALS env to be set to point to the key file

gsutil

gcloud auth ...

GOOGLE_APPLICATION_CREDENTIALS
