Question 2

How does Packer interact with system images?

APacker has to be installed within the target image and is executed during the image's first boot in order to execute preparation tasks.

BPacker installs a client within the image which has to be run periodically via cron in order to retrieve the latest template from the Packer server and apply it locally.

CPacker periodically connects through the network to the Packer daemons of all running Packer images in order to re-apply the whole template to the running instance.

DPacker downloads and extracts an image in order to make changes to the image's file system, repack the modified image and upload it again.

EPacker creates an instance based on a source image, prepares the instance through a network connection and bundles the resulting instance as a new system image.
