LCA as Google functions: Deployment

Learn how to deploy a Google Cloud Run function in Google Cloud by preparing the environment, enabling required APIs, and deploying your custom logic using a ZIP file containing a JAR package.

Before proceeding with the deployment, ensure the following prerequisites are met:

You have a Google Cloud account with appropriate permissions to deploy Cloud Run functions.
You have permission to upload files to Google Cloud Storage.
You have enabled the Cloud Functions API in your project.
The JAR file containing your custom logic is ready for deployment.

Google LCAs provide a way to build custom logic into operations such as create, update, delete, and others on entities, relationships, and graphs.

To deploy a Google function:

Navigate to your Google Cloud Console and log in.
Create or select an existing project.
Ensure you're working in the correct project where you want to deploy your function.
Go to APIs & Services > Library. Enable the Cloud Functions API, if not enabled already.
In Google Cloud Console, navigate to Cloud Run functions.
1. Select Create Function.
2. Provide a Name for the function.
3. Choose the Region where you want to deploy the function.
4. Set the Trigger type to HTTPS.
In the Runtime - Build and Security Settings, assign an appropriate Service Account for the Google function.

Select Next.

Note:
Google functions only accept the ZIP archive file format.
Upload the ZIP file
1. Select the Runtime environment from the Code page.
  
  Note: We recommend you use the most recent Java version, currently version 21.
2. From the Source Code section, choose one of the following options:
  
  ZIP Upload: Upload the ZIP file from your local machine.
  
  ZIP from Cloud Storage: Select the ZIP file from a Google Cloud Storage bucket.
3. Specify the entry point for your function using the format: <package-name>.<ClassName>.
  This is the fully qualified name of the class that contains your function logic.
4. Select Deploy.
  
  Note:
  Ensure you note the Function URL as this is used in L3 configuration.
5. Copy the function URL once your function is deployed.
