We have a list of transactions, each transaction is a tuple (P1, P2, t,s,hash), where s is equal to the amount of money transferred from person P1 to person P2 at time t and hash is the key of the tuple.

We have the current date in second since 01-01-2023.

Building the docker image

We built the docker image using the following command in the terminal

docker build -t flask-app . 

Using the docker images command

Running the docker image in a container

sudo docker run -it -p 5000:5000 -d flask-app

This will lauch our flask application on localhost port 5000 We use docker ps to display running containers

We can see at the end we have the follow result

Update

We have already implemented all the features in the app.py file before releasing
