title: How to set path to chromedriver in Google Cloud Composer
body: <p>I am attempting to run a DAG that will use selenium to scrape a web page every week on Cloud Composer. </p>
  
  <p>I have already tried to give the path when creating the WebDriver.Chrome() instance to a driver that I uploaded to GCS, though I imagine this is not the best way to do this. </p>
  
  <p>Airflow is giving this error</p>
  
  <pre><code>Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
  </code></pre>
  
  <p>If you have any tips as to updating Cloud Composer's PATH variable, would be greatly appreciated. If I need to put in more info, drop a comment and I'll add on.</p>
