How to Deploy as Google Cloud Function


◷ Reading Time: 5 minutes

You can deploy a project as a Google Cloud Function. By doing this, you can get the service URL of your project without needing to install FlexRule Server.

We are deploying this Decision Table as an example. It takes a person’s age as an input and outputs the title according to the age range.

This is the input object of the decision table.


The complete project is attached at the end of the page.

How to Deploy

Open your project’s entry document.
In this example, the decision table is the entry document.

Click on the Package Builder.

Add your package details such as,

  • Package identifier
  • Package version
  • Service version
Go to Deployment tab and select Google Cloud Function.

Enter Google Cloud subscription details. For more information about Service Account Key refer to How to retrieve Google Cloud service account key.

For the Service Account Key, click on the key icon to open a file browser and locate your Service Account Key json file or the template json file as discussed below.

Optionally, you can create a JSON according to the following template and save it as a JSON file (.json). Then use the button
to upload the created JSON file with Google Cloud subscription details.

"Keypath": "C:\Downloads\fr-project-305102-3d18b1f31767.json",
"Bucket": "flexrule-service",
"Location": "us-west2"

If the specified Bucket doesn’t exist yet, it will create a new one under the selected region.

Location depends on Tier Pricing. Please refer to this link to find out more. If the service account key is not valid, the Location dropdown will be empty.

Select the Runtime license file. The Runtime folder will be automatically taken from the Runtime path you have defined in your project.

Click Publish.

Once the package was created successfully, you will see a confirmation message.

The deployment will happen in the background. In the background task window, you will see the list of deployment tasks.

The complete list of deployment tasks can be seen along with their status.

If there are any errors, you can see the specific task(s) with the error(s).

Select the errored task and click on View Task Result to see the detailed exception.

Once the deployment is completed you can see the completed status with the icon .

Click on View Task Result to see the results.

You will receive the URLs of the successful deployment.
