Deploy Hello World application on GCP App Engine | Google Cloud Platform | Tutorial for Beginners

Introduction

This tutorial will guide you through the process of deploying a simple "Hello World" application on Google Cloud Platform's App Engine. This beginner-friendly guide will help you understand the basic steps involved in deploying applications using GCP, making it a great starting point for anyone new to cloud computing.

Step 1: Set Up Your Google Cloud Account

• Visit the Google Cloud Platform website.
• Sign in with your Google account or create a new one if necessary.
• If you are a new user, you may be eligible for a free trial that provides credits for using GCP services.

Step 2: Create a New Project

• In the GCP Console, navigate to the project dropdown at the top of the page.
• Click on "New Project."
• Enter a name for your project (e.g., "HelloWorldApp") and select your organization if applicable.
• Click "Create."

Step 3: Enable App Engine

• In the GCP Console, find "App Engine" in the navigation menu.
• Click on "Dashboard" and then select "Create Application."
• Choose your preferred region for the application.
• Click "Next" and follow the prompts to set up the App Engine.

Step 4: Set Up Your Development Environment

• Install the Google Cloud SDK on your local machine. You can download it from this link.
• After installation, open your terminal or command prompt.
• Initialize the SDK with the command:

  gcloud init
  

• Follow the prompts to log in and select your newly created project.

Step 5: Download the Sample Application

• Clone the sample application repository using Git:

  git clone https://github.com/GoogleCloudPlatform/python-docs-sample
  

• Navigate to the cloned directory:

  cd python-docs-sample/appengine/hello_world
  

Step 6: Deploy the Application

• Before deployment, ensure that you have the App Engine configuration file (app.yaml) in your application directory. This file defines your application settings.
• Deploy the application using the command:

  gcloud app deploy
  

• Confirm the deployment when prompted.

Step 7: Access Your Application

• After the deployment is complete, you can access your application using the URL provided in the terminal output.
• The URL typically follows the format: https://<your-project-id>.appspot.com.
