A very simple Flask application.
1- In the root directory, build the docker image using command docker build -t my_flask .
2- Once the image is build, run the container using command docker run -p 5000:5000 my_flask.
3- You can verify the running container by docker ps
4- On the endpoint localhost:5000/calculator, submit the POST json request with two numbers, it will add both of them and display the results.
A sample json input:
{
"num1" : 150.5,
"num2" : 90.5
}
