Create a new app in google app engine

Here's a step-by-step guide to creating a new app in Google App Engine:

Prerequisites:

  1. You need a Google account to create an App Engine app.
  2. You need to have the Google Cloud SDK installed on your computer.

Step 1: Create a new project in the Google Cloud Console

  1. Go to the Google Cloud Console (console.cloud.google.com) and sign in with your Google account.
  2. Click on the "Select a project" dropdown menu and click on "New Project".
  3. Enter a project name, select an organization (if you have one), and click on "Create".

Step 2: Enable the App Engine API

  1. In the sidebar, click on "APIs & Services" and then click on "Dashboard".
  2. Search for "App Engine" in the search bar and click on the result.
  3. Click on the "Enable" button to enable the App Engine API.

Step 3: Create a new App Engine app

  1. In the sidebar, click on "App Engine" and then click on "Create Application".
  2. Enter a unique app ID (e.g., "myapp") and a location (e.g., "us-central1").
  3. Choose a runtime (e.g., "Python 3.9" or "Java 11") and click on "Create".

Step 4: Set up your App Engine app

  1. In the App Engine dashboard, click on the "Settings" icon (three vertical dots) next to your app ID.
  2. Click on "App settings" and enter the following information:
    • App name: Enter a name for your app (e.g., "My App").
    • App description: Enter a brief description of your app.
    • Default language: Choose the default language for your app (e.g., "English").
  3. Click on "Save" to save your app settings.

Step 5: Create a new directory for your app

  1. Create a new directory on your computer for your app (e.g., "myapp").
  2. Navigate to the directory in your terminal or command prompt.

Step 6: Initialize your app with the App Engine SDK

  1. Run the following command to initialize your app with the App Engine SDK:
    gcloud app create --project=<your-project-id> --region=<your-region>

    Replace <your-project-id> with the ID of your project and <your-region> with the region you chose earlier (e.g., "us-central1").

Step 7: Create a new file for your app

  1. Create a new file in your app directory called app.yaml (this file will contain configuration settings for your app).
  2. Add the following code to the file:
    runtime: python39

    This sets the runtime for your app to Python 3.9.

Step 8: Write your app code

  1. Create a new file in your app directory called main.py (this file will contain the code for your app).
  2. Write your app code in this file (e.g., a simple "Hello, World!" app).

Step 9: Deploy your app

  1. Run the following command to deploy your app:
    gcloud app deploy app.yaml

    This will deploy your app to the App Engine platform.

Step 10: Test your app

  1. Once your app is deployed, you can test it by visiting the URL:
    https://<your-app-id>.appspot.com

    Replace <your-app-id> with the ID of your app.

That's it! You've created a new App Engine app.
