+# Imagine this file as a recipe for setting up a virtual computer.

+# Dockerfiles typically start with a 'base image'. There are loads of these
+# and you can find them at hub.docker.com.
+# We're going to use a base image for Python veresion 3.11
+FROM python:3.11
+
+# This base image contains essentially everything necessary for a 'virtual
+# computer'. It has a terminal, certain basic commands, and of course Python.
+
+# We run a command to install `pipenv`
+RUN pip install pipenv
+
+# We'll need our app's files in the container in order to be able to run them!
+# We copy them in from the current directory to the folder `/app` in
+# our virtual computer. Reminder `.` means 'the current directory'
+COPY . /app
+
+# We set the working directory for commands from this point on
+WORKDIR /app
+
+# We run `pipenv install` to install our project's dependencies. Since we've
+# copied in our `Pipfile`, `pipenv` will use that to get a list of dependencies.
+# We include a couple of extra options suitable for deployment.
+RUN pipenv install --system --deploy
+
+# At this point we've set up our virtual computer, but we've not _yet_ run our
+# application. And we're not going to! We're just setting up the container
+# so that it's ready to do so when we tell it.
+
+# So we're going to tell Docker here that when we _do_ want to run it, this is
+# what it should run:
+CMD ["python", "app.py"]
