<h1>Answer My Own Question</h1>

<p>I recently upgraded to Airflow 1.10 which introduced the <code>KubernetesPodOperator</code> however whenever I use it I see the following error in the webserver: <code>No module named 'kubernetes'</code>. Why does this happen and how can I fix it?</p>

<p>This happens because the kubernetes library isn't installed with vanilla airflow. You can fix this by running <code>pip install "apache-airflow[kubernetes]"</code>. </p>
