Set Environment Variables

(Note: If you are using OAuth2, you will also need the environment variables described here.)

Setting these two environment variables will support a smooth authentication process that occurs in the background:

• GOOGLE_CLOUD_PROJECT – Project ID of the project that you will authenticate to.

• GOOGLE_APPLICATION_CREDENTIALS – Path to a key file containing your service account credentials.

To set these, replace the following angle brackets (<>) and everything between them with your values.

export GOOGLE_CLOUD_PROJECT="<my-project-id>"
export GOOGLE_APPLICATION_CREDENTIALS="</local/path/to/GCP_auth_key.json>"

If you open a new terminal, you will need to set the variables again. Conda can simplify this. The following commands will configure it to automatically set these variables when your environment is activated, and erase them when it is deactivated.

Activate your Conda environment and make sure the variables GOOGLE_CLOUD_PROJECT and GOOGLE_APPLICATION_CREDENTIALS are set. Then:

# create the activate/deactivate files if they don't already exist
mkdir -p "${CONDA_PREFIX}/etc/conda/activate.d"
mkdir -p "${CONDA_PREFIX}/etc/conda/deactivate.d"
touch "${CONDA_PREFIX}/etc/conda/activate.d/env_vars.sh"
touch "${CONDA_PREFIX}/etc/conda/deactivate.d/env_vars.sh"

# store the variables to export them automatically when the environment is activated
echo "export GOOGLE_CLOUD_PROJECT=${GOOGLE_CLOUD_PROJECT}" >> "${CONDA_PREFIX}/etc/conda/activate.d/env_vars.sh"
echo "export GOOGLE_APPLICATION_CREDENTIALS=${GOOGLE_APPLICATION_CREDENTIALS}" >> "${CONDA_PREFIX}/etc/conda/activate.d/env_vars.sh"

# remove the variables automatically when the environment is deactivated
echo "unset GOOGLE_CLOUD_PROJECT" >> "${CONDA_PREFIX}/etc/conda/deactivate.d/env_vars.sh"
echo "unset GOOGLE_APPLICATION_CREDENTIALS" >> "${CONDA_PREFIX}/etc/conda/deactivate.d/env_vars.sh"
