Create a simple Python Flask application

o Your application should have two different routes

$$ GET $/$add $-$ uses the query string to obtain two input values and returns the result of the

addition of those two values

$$ POST $/$sub $-$ uses the post body to obtain two input values and returns the result of the

subtraction of those two values

o Create the needed requirements.txt file

$$ Create three different docker images from that one application

o Image $1$

$$ Base image $=$ ubuntu

$$ Host port $=5001,$ Container Port $=5000$

o Image $2$

$$ Base image $=$ alpine

$$ Host port $=5002,$ Container Port $=5000$

o Image $3$

$$ Base image $=$ python

$$ Host port $=5003,$ Container Port $=5003$
