title: Install Docker on Agent in Team Services
body: <p>Is it possible to install Docker on the build agent or set it as a requirement?</p>
  
  <p>My tests try to run Docker on the command line but this doesn't seem to work.</p>
  
  <p>I would have expected to add it as a <code>Demand</code> but adding <code>docker</code> doesn't work.</p>
