Drupal CMS

Part of USAGov Architecture patterns

The Drupal CMS runs Drupal plus some additional services in order to build the static assets for the Public static web site:

• Drupal
• nginx
• shell scripts
  • Run drupal/tome to generate static HTML
  • Assemble static HTML plus other assets
  • Copy all to S3 (aws-s3)
• Cron (via s6 overlay)
