Dockerizing Python

Okay, so our first attempt at Dockerizing the Python script didn't work... let's fix it!

The problem is our image doesn't have the python3 interpreter installed, so it can't run the script.

Assignment

Update the Dockerfile.py to use RUN commands to install Python. If you're up for the challenge, figure out how to install Python on your own. (If not, I've included the Dockerfile below in the tip section.)
Rebuild the image:
```
docker build -t bookbot -f Dockerfile.py .
```
It might take a few minutes to build the image... we're installing an entire Python interpreter after all!

Maybe now you can see why I like Go so much...
Run the image in a new container:
```
docker run bookbot
```

If Bookbot ran, then you did it correctly! We've bundled up the Python script, its required data, and its required runtime all into a nice little container image!

Run and submit the CLI tests.

Common technologies often have images available for ease of use. See the Python Official Image from DockerHub Official Images.

Tip

# Build from a slim Debian/Linux image
FROM debian:stable-slim

RUN apt-get update && apt-get install -y python3

# Copy our code into the image
COPY main.py main.py

# Copy our data dependencies
COPY books/ books/

# Run our Python script
CMD ["python3", "main.py"]
