Django - Docker - The Application Default Credentials are not available

Question

I would like to use Google Cloud SDK with Django project in Docker container. Let's assume that I would like to use

from google.cloud import vision
from google.cloud.vision import types

When I install google-cloud using requirements.txt file I get error shown below. On my local machine without container it works properly. Does anyone have an idea how can I solve this?

django_1 | oauth2client.client.ApplicationDefaultCredentialsError: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

UPDATE I work on MacBook and I found on this website this:

docker run --rm -it -v ~/.config/gcloud:/.config/gcloud google/cloud-sdk

At this moment I get errors shown below. Any ideas how can I solve this?

Try this docker run -e "GOOGLE_APPLICATION_CREDENTIALS=$GOOGLE_APPLICATION_CREDENTIALS" --rm -it -v ~/.config/gcloud:/.config/gcloud google/cloud-sdk — Tarun Lalwani
@TarunLalwani After using your command there is root@4271b8a28802:/# and still the same error. — user7304253
can you run env on your mac and post all google related environment variables? Make any value that need to be private replaced by dummy value. — Tarun Lalwani
@TarunLalwani Did you mean information that I added to the updated question? — user7304253
You need to use service account cloud.google.com/storage/docs/…. Read this google-cloud-python.readthedocs.io/en/latest/core/auth.html — Tarun Lalwani

The issue is the you are mounting the folder to / instead of /root/ where the config will be checked for

change

docker run --rm -it -v ~/.config/gcloud:/.config/gcloud google/cloud-sdk

to

docker run --rm -it -v ~/.config/gcloud:/root/.config/gcloud google/cloud-sdk

If you are use docker-compose then add it to the yaml of the particular server

volumes:
  - ~/.config/gcloud:/root/.config/gcloud
