  <pre><code>curl -sSO https://dl.google.com/cloudagents/install-logging- agent.sh 
  sudo bash install-logging-agent.sh
  apt-get update apt-get install -yq git supervisor python python-pip
  pip install --upgrade pip
  virtualenv useradd -m -d /home/pythonapp pythonapp
  export HOME=/root
  git clone -b steps https://github.com/GoogleCloudPlatform/getting-started-python.git
  /opt/app virtualenv -p python3 /opt/app/gce/env
  source /opt/app/gce/env/bin/activate
  /opt/app/gce/env/bin/pip install -r /opt/app/gce/requirements.txt 
  chown -R pythonapp:pythonapp /opt/app 
  # Put supervisor configuration in proper place
  cp /opt/app/7-gce/python-app.conf /etc/supervisor/conf.d/python-app.conf
  cat &gt;/etc/supervisor/conf.d/python-app.conf &lt;&lt; EOF
