Technical requirements

The toolset we are using will only change slightly in this chapter. Besides the classical Docker and minikube, we will need to install Python3. Let's take a look:

1. Python can be installed by following the instructions at https://realpython.com/installing-python/.
2. We will also need to install the apache_beam package using pip:

   $ python3 =m pip install apache_beam

   If something goes wrong, make sure you have the latest version of pip by using the following command:

   $ python3 =m pip install --upgrade pip

3. The highest fully Apache Beam-supported version of Python is 3.7. If you have a higher version installed and do not want to downgrade, you can use the pack-beam pod in minikube, which has the correct Python version bundled with it. All the examples in this chapter can be run using the following command:

   $ kubectl exec -t packt-beam -- \
       /usr/local/bin/<name_of_script.py>

You will also need to have a basic understanding...
