In this article, we will guide you through the process of deploying your Flask app to Google Cloud, making your app accessible globally while freeing up your time to work on what truly matters.

Google Cloud is a powerful platform that offers a wide range of services, including virtual machines, storage, databases, and more. One of the best ways to utilize its features is by deploying your Flask app to Google App Engine. Google App Engine is a completely managed platform that enables you to develop web and mobile applications that can scale up or down automatically according to demand.

Before we dive into the deployment process, make sure you have the necessary tools installed on your computer. These tools include the Google Cloud SDK, Git, and Python. Once you have these tools, create a new project on the Google Cloud Console and download your project’s credentials.

Next, let’s set up our Flask app. Make sure your app follows the standard Flask file structure and that it contains all necessary files, including the main app.py file and requirements.txt file. We’ll also need to create an app.yaml file that tells Google App Engine what to do with our app.

When it comes to deployment, there are two methods: standard and flexible environment. The standard environment is suitable for small to medium-sized apps with moderate traffic, while the flexible environment is designed for large and complex apps with high traffic.

Nowadays, users expect fast-loading websites and apps. In fact, research shows that every second added to a website’s loading time reduces conversions by 7%. By deploying your Flask app to Google App Engine, you can take advantage of the platform’s fast loading times and incredible scalability that will keep your users happy and engaged.

Another great advantage of deploying your Flask app to Google Cloud is that it allows you to easily implement features like auto-scaling, traffic splitting, and authentication. You can also use other Google Cloud services like Cloud SQL or Cloud Functions to extend the functionality of your app.

Once we’ve successfully deployed our app, we can use the Cloud Console to monitor its usage and make any necessary changes. The console provides us with insights into traffic, errors, resource utilization, and more.

Don’t let server maintenance and scaling issues prevent you from focusing on building great applications. By deploying your Flask app to Google Cloud, you can take advantage of a managed platform that will allow you to seamlessly scale your app, save time, and ultimately increase your user base.

In conclusion, leveraging Google Cloud for deploying your Flask app is a smart choice. It allows for better scalability, easier management, and faster load times. Hopefully, this article has given you an idea of how to get started with deploying your Flask app to Google Cloud. Start deploying your Flask app to Google Cloud and enjoy all the benefits of a truly managed platform.


Introduction

Google Cloud Platform has the potential to be an ideal place to deploy your Flask app when you're preparing to take it to production. There are many providers in the market, but Google Cloud Platform stands out for its size, features, and the number of different services it provides. With that being said, we will be going through the process of deploying a Flask App to Google Cloud Platform without using containers.

Requirements

In order to follow along with this article, there a few major requirements you will need:

  • A google cloud platform account - You can create one here
  • A Flask App - If you do not have one, go ahead and create one by following the tutorial at their official website here
  • Python 3.x installed on your machine

The Process

Step 1 - Create A Google Cloud Project

The first step is to create a project on the Google Cloud Platform. Go to the create project page, give it a name, and click create. Remember your project ID as we will need it later on.

Step 2 - Enable the Required APIs

We will need to enable a few APIs in order to make our app work properly, these are:

  • Google App Engine Admin API
  • Cloud Logging API
  • Cloud Monitoring API
  • Cloud Build API

To enable these APIs, go to the Google Cloud Platform console, select your project, and go to APIs and services -> Dashboard. From there, you can search for the necessary APIs and enable them.

Step 3 - Create an App Engine Application

We will now create an App Engine application to deploy our Flask app to. To create the App Engine application, navigate to the App Engine section in the Google Cloud Platform console, click CREATE APP ENGINE APP and follow the prompts. When asked to choose the environment, select Standard and choose your preferred region and language (Python 3.7).

Step 4 - Update Your App Settings

The next step is to update your Flask application's settings. Ensure your Flask app listens on all interfaces by setting the host to '0.0.0.0' and a port (let's say port 8080).

```if __name__ == '__main__': app.run(host='0.0.0.0', port=8080)```

Step 5 - Install and Configure gcloud SDK

The gcloud SDK allows us to interact with our applications and Cloud Platform directly from the command line. Go ahead and follow the installation instructions for Windows, MacOS or Linux. Ensure you connect your system to the correct Google Project.

Step 6 - Writing a deployment script

We will now create a deployment script that helps streamline our deployments. You can create the script and save it in your app's directory on your local machine.

```#!/bin/bashgcloud app deploy```

This simple deployment script will use gcloud app deploy to deploy our App Engine application. You can then run this script at any point to deploy your application. Ensure you have installed and initialized the Google Cloud SDK before running this command.

Step 7 - Deploy Your Application

To deploy our application, navigate back to your terminal and run the script:

```./deploy.sh```

After successful deployment, you should see the URL link that you can use to view your application. Open that link, and voila, your Flask application is now live!

Conclusion

We just went through the process of deploying a Flask app without using containers on the Google Cloud Platform. We created the necessary Google Cloud configuration, used the Google Cloud SDK, and executed a couple of commands to get our application online. Of course, deploying apps does come with its share of challenges, but Google Cloud Platform makes it easier than most other providers. Happy Deploying!

Deploy Flask App To Google Cloud

Are you a Python developer and looking to deploy your Flask web application on Google Cloud? You are in the right place. In this article, we will guide you on how to deploy your Flask app to Google Cloud.

Google Cloud offers multiple ways to deploy your Flask app. One of the easiest ways is to use the Google App Engine, which is a fully managed serverless platform.

Getting Started

Before we dive into the deployment process, make sure you have the following prerequisites:

  • A Google Cloud account
  • A Flask application (can be a sample app)
  • The Google Cloud SDK installed on your local machine
  • Basic knowledge of the command line interface (CLI)

Once, you have all the prerequisites ready, let's move on to the next step where we will create an App Engine project.

Create an App Engine Project

First, we need to create an App Engine project. Follow the below steps:

  1. Login to Google Cloud Console
  2. Select the project from the drop-down menu or create a new one
  3. Click on Navigation Menu → App Engine → Dashboard
  4. Click on Create Application
  5. Enter the desired Application ID and select the Region where you want to host your app
  6. Click on Create

Now, wait for a few minutes until the App Engine project is created. Once, it's created, we can move on to the next step.

Configure Your Flask App

Before we deploy the Flask app on Google Cloud, we need to make some changes to our app. Follow these steps:

  1. Add the google-cloud-logging and google-cloud-storage packages to your app's requirements.txt file if it doesn't have them already
  2. Create a new file named app.yaml in your Flask app's root directory
  3. Add the following code to the app.yaml file:
```runtime: python37entrypoint: gunicorn -b :$PORT main:apphandlers:- url: /static static_dir: static- url: /(.*\.(gif|png|jpg|ico|txt))$ static_files: \1 upload: (.*\.(gif|png|jpg|ico|txt))$- url: /.* secure: always redirect_http_response_code: 301 script: auto```

This YAML file specifies the information that the App Engine needs to know to run your Flask app in a container. It also specifies the entry point of your application, which is main:app.

Next, update your Flask app file with the following line at the end:

```if __name__ == '__main__': app.run() ```

Replace the above line with:

```if __name__ == '__main__': app.run(host='127.0.0.1', port=8080, debug=True) ```

These changes will allow your app to be run locally and also in the Google Cloud environment.

Deploy Your Flask App

Now that we have made the required changes to our Flask app and created the App Engine project, we are ready for deployment. Follow these steps:

  1. Open the terminal and navigate to the root directory of your Flask app
  2. Run the following command to authenticate your Google Cloud account
```gcloud auth login```

Ensure that you are using the correct Google Cloud project (the one you just created for this app). Run the following command to set the current project:

```gcloud config set project [YOUR_PROJECT_ID]```

Replace [YOUR_PROJECT_ID] with the ID of your Google Cloud project.

Next, deploy your app using the following command:

```gcloud app deploy```

It may take a few minutes to deploy your Flask app to Google Cloud.
