How to Create a GCP Function using Node.js and Deploy to GCPGoogle Cloud Platform (GCP) offers a robust serverless computing service called Cloud Functions, which allows developers to create and deploy small, single-purpose functions that respond to events and execute in a scalable and efficient manner. In this article, we will walk through the process of creating a GCP Function using Node.js and deploying it to the GCP environment.
PrerequisitesBefore we dive into the implementation, make sure you have the following prerequisites in place:
1. A GCP account with appropriate access and permissions.
2. The Google Cloud SDK installed on your local machine.
Step 1: Set Up the Development EnvironmentTo begin, ensure that you have Node.js installed on your local machine. You can download it from the official Node.js website. Once installed, open a terminal and verify that Node.js is correctly installed by running the following command:
Step 2: Create a New GCP ProjectNext, navigate to the Google Cloud Console (https://console.cloud.google.com/) and create a new project by clicking on the project dropdown and selecting "New Project". Give your project a meaningful name and click "Create".
Step 3: Enable Cloud Functions APIIn the Cloud Console, navigate to the "APIs & Services" section and select "Library". Search for "Cloud Functions API" and enable it for your project.
Step 4: Set Up AuthenticationTo authenticate your local machine with GCP, you need to generate a service account key. In the Cloud Console, navigate to "IAM & Admin" and select "Service Accounts". Create a new service account, grant it the necessary permissions (e.g., Cloud Functions Developer), and generate a JSON key file.
Save the JSON key file to a secure location on your local machine.
Step 5: Install and Initialize the Google Cloud SDKOn your local machine, install the Google Cloud SDK by following the instructions provided in the official documentation (https://cloud.google.com/sdk/docs/install). Once installed, open a terminal and run the following command to initialize the SDK and authenticate with GCP:
Step 6: Set the Project and RegionSpecify your GCP project and region by running the following commands in the terminal:
Step 7: Create a New FunctionNow, it's time to create a new GCP function. In your terminal, navigate to the directory where you want to store your function's code. Run the following command to initialize a new function:
Create a function that will be called when any file we be uploaded in the DEMO_BUCKET
Step 9: Deploy the FunctionTo deploy the function to GCP, run the following command in the terminal:
Deploye the function, this function will be called when any file will be uploaded in the DEMO_BUCKET
Ensure that you are in the same directory where your function's code is located.
