Requirements

  • Python (3.8+)
  • FastAPI
  • Postgresql/Sqlite

Running Application

First, we need to create virtual environment and install dependencies. After successful installation, we will run the backend application. Following are the commands which does the same.

virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt
cd src
python main.py

Output:

INFO:     Started server process [16967]
INFO:     Waiting for application startup.
Database created
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)

Test whether the application is started properly or not, just hit the docs API link from below and you should see the swagger api response on browser.

Running Tests

cd src
python test.py

Deployment

1. Docker Compose

Docker compose will first build the api image using Dockerfile and then run the postgres and api containers

docker compose up

2. Kubernetes

For deployment in Kubernetes cluster you can refer the k8s folder for .yaml based configuration files. Assuming you have minikube cluster setup and a kubectl, then you can simply run the following commands to deploy the application and postgresql.

kubectl apply -f k8s/api-deployment.yaml
kubectl apply -f k8s/postgres-deployment.yaml
