Let's start by creating the folder in which we will place the application files. First, create a directory called notifier and go into that directory so we can create the virtual environment:
mkdir notifier && cd notifierWe create the virtual environment using pipenv:
pipenv --python ~/Installs/Python3.6/bin/python3.6Remember that if Python 3 is in our path, you can simply call:
pipenv --threeTo build this service we are going to use the micro web framework Flask, so let's install that:
pipenv install flaskWe are also going to install the requests package, which will be used when sending requests to the order service:
pipenv install requestsThat should be everything we need for now. Next, we are going to see how we can use AWS Simple Email Service to send emails from our applications.
