GCP Firestore (Datastore mode) Architecture

Prerequisites

• Follow the Connecting to GCP guide.

Existing Database

Step 1: Accessing GCP Firestore Instance from a DevBox

1. Connect to your DevZero workspace.

2. Store the Google Authentication Credentials on the workspace.

3. Install Python and PIP:

sudo apt update
sudo apt install python3 python3-dev python3-venv
sudo apt-get install wget
wget https://bootstrap.pypa.io/get-pip.py

4. Install Firestore Admin API:

pip install --upgrade google-cloud-datastore

5. Set the GOOGLE_APPLICATION_CREDENTIALS environment variable.

export GOOGLE_APPLICATION_CREDENTIALS=/path/to/the/key.json

6. Write a Python scipt to test the Firestore Admin API Connection:

from google.cloud import datastore

datastore_client = datastore.Client(project='content-gen-418510', database='devzero-test')

if datastore_client:
    print('Connected')
else:
    pass

7. Run the Python Script:

python3 <file-name>.py

If the connection is successful, you should see "Connected" printed in the terminal output.

    print('Connected')
else:
    pass

7. Run the Python Script:

python3 <file-name>.py

If the connection is successful, you should see "Connected" printed in the terminal output.
