Run Flask App [MyGarage] as a Service in Ubuntu

In my previous post I talked about how I created a Flask app and hosted it on AWS Reserved EC2 Instance.

But hosting of the app was more like executing Gunicorn command and thats it. However I needed my app to be running in background also, even if system restarts.

So, I decided to create it as a service and its very simple.

First, I created file mygarage.service under /etc/systemd/system folder

and it contains below code:

[Unit]
Description=Gunicorn instance to serve Flask app: MyGarage
After=network.target

[Service]
User=ubuntu
WorkingDirectory=/home/ubuntu/MyGarage
ExecStart=gunicorn -b 0.0.0.0 app:app

[Install]
WantedBy=multi-user.target

And thats it.

All I needed to do next was

sudo systemctl start mygarage

to start the service and

sudo systemctl enable mygarage

to start it whenever machine starts

We can check the status of service by using

sudo systemctl status mygarage

My application is running successfully as a service.
