In this tutorial, we will walk through the process of deploying a Flask app to AWS (Amazon Web Services). AWS is a cloud computing platform that offers a wide range of services, including hosting and running applications.<\/p>\n
Before getting started, make sure you have the following prerequisites:<\/p>\n
The first step is to create an EC2 (Elastic Compute Cloud) instance, which will act as a virtual server to host your Flask app.<\/p>\n
Once the instance is created, note down the public IP address or DNS name of your instance, as you will need it to access your Flask app later.<\/p>\n
To deploy a Flask app to your EC2 instance, you need to establish a secure connection to the instance using SSH (Secure Shell).<\/p>\n
path\/to\/key.pem<\/code> with the actual path to your private key file:\nchmod 400 path\/to\/key.pem\n<\/code><\/pre>\n<\/li>\n- Connect to the EC2 instance using the SSH command. Replace
your-instance-public-ip<\/code> with the actual public IP address or DNS name of your instance:\nssh -i path\/to\/key.pem ec2-user@your-instance-public-ip\n<\/code><\/pre>\nYou might see a warning about the authenticity of the host. Simply type yes<\/code> to continue the connection.<\/p>\n<\/li>\n<\/ol>\nCongratulations! You are now connected to your EC2 instance.<\/p>\n
Step 3: Install Dependencies<\/h2>\n
Next, you need to install the necessary dependencies on your EC2 instance to run your Flask app.<\/p>\n
\n- Update the package index on your EC2 instance:\n
sudo yum update -y\n<\/code><\/pre>\n<\/li>\n- Install Python and pip on your EC2 instance:\n
sudo yum install python3 -y\nsudo amazon-linux-extras install python3.8 -y\nsudo yum install python3-pip -y\n<\/code><\/pre>\n<\/li>\n- Install virtualenv to isolate your Flask app’s environment:\n
sudo pip3 install virtualenv\n<\/code><\/pre>\n<\/li>\n- Create a new virtual environment for your Flask app:\n
python3 -m venv myenv\n<\/code><\/pre>\n<\/li>\n- Activate the virtual environment:\n
source myenv\/bin\/activate\n<\/code><\/pre>\n<\/li>\n- Install Flask and any other dependencies required by your Flask app:\n
pip install Flask\n<\/code><\/pre>\n<\/li>\n<\/ol>\nNow your EC2 instance is ready to run your Flask app.<\/p>\n
Step 4: Upload Your Flask App<\/h2>\n
To deploy your Flask app, you need to upload the app’s files to your EC2 instance.<\/p>\n
\n- Open a new terminal window on your local machine (while keeping the SSH connection to your EC2 instance open).<\/li>\n
- Change to the directory where your Flask app’s files are located.<\/li>\n
- Use the
scp<\/code> command to securely copy your app’s files to your EC2 instance. Replace path\/to\/key.pem<\/code> with the actual path to your private key file, and your-instance-public-ip<\/code> with the actual public IP address or DNS name of your instance:\nscp -i path\/to\/key.pem -r .\/* ec2-user@your-instance-public-ip:\/home\/ec2-user\/\n<\/code><\/pre>\n<\/li>\n- Switch back to the SSH connection to your EC2 instance and navigate to the directory where you uploaded your app’s files:\n
cd \/home\/ec2-user\/\n<\/code><\/pre>\n<\/li>\n- Run your Flask app on the EC2 instance:\n
python app.py\n<\/code><\/pre>\nIf you experience any issues related to port conflicts, you can run the Flask app on a different port by specifying the -p<\/code> option followed by the desired port number.<\/p>\n<\/li>\n<\/ol>\nNow your Flask app should be running on your EC2 instance, accessible through the public IP address or DNS name of the instance. You can test it by opening a web browser and navigating to `http:\/\/your-instance-public-ip`.<\/p>\n
Step 5: Run the Flask App as a Service<\/h2>\n
Currently, your Flask app is running in the foreground, which means it will be shut down if your SSH connection to the EC2 instance is closed. To keep your Flask app running even after you disconnect, you need to run it as a service.<\/p>\n
\n- Press
Ctrl+C<\/code> to stop your Flask app.<\/li>\n- Create a systemd service file with the following command:\n
sudo nano \/etc\/systemd\/system\/flaskapp.service\n<\/code><\/pre>\n<\/li>\n- Add the following content to the file:\n
[Unit]\nDescription=Flask App Service\nAfter=network.target\n\n[Service]\nUser=ec2-user\nWorkingDirectory=\/home\/ec2-user\/\nExecStart=\/home\/ec2-user\/myenv\/bin\/python app.py\nRestart=always\n\n[Install]\nWantedBy=default.target\n<\/code><\/pre>\n<\/li>\n- Save and close the file by pressing
Ctrl+X<\/code>, then Y<\/code>, and finally Enter<\/code>.<\/p>\n<\/li>\n- \n
Enable the Flask app service to start automatically at boot time:<\/p>\n
sudo systemctl enable flaskapp\n<\/code><\/pre>\n<\/li>\n- Start the Flask app service:\n
sudo systemctl start flaskapp\n<\/code><\/pre>\n<\/li>\n<\/ol>\nCongratulations! Your Flask app is now running as a service on your EC2 instance.<\/p>\n
Conclusion<\/h2>\n
In this tutorial, you learned how to deploy a Flask app to AWS using an EC2 instance. We covered the process of creating an EC2 instance, connecting to it, installing dependencies, uploading the app’s files, and running the app as a service. With your Flask app deployed on AWS, it can be accessed by anyone with an internet connection.<\/p>\n
Keep in mind that this tutorial covers the basic steps to deploy a Flask app to AWS. Depending on your specific requirements, you might need to configure additional services or make further optimizations.
