PullPreview writes the following environment variables to /etc/pullpreview/env on the preview instance and uses them during deployment:

• PULLPREVIEW_PUBLIC_DNS: generated public DNS name for the preview
• PULLPREVIEW_PUBLIC_IP: public IP address of the preview instance
• PULLPREVIEW_URL: full preview URL, including scheme and port

These values are available to:
