How to create new windows AMI with packer

Question

I have an EC2 running Windows with 2 volumes, one for OS and one for DB and application. I've tried to search in Packer docs for creating new updated image but all I've found is that I need to provide existing AMI ID, which currently I don't have. How can I use packer to create an update image of the running instance?

Answer 1

From the Packer documentation:

What is Packer?

Packer is an open source tool for creating identical machine images for multiple platforms from a single source configuration. Ref

Packer can't create an image from a running instance and that is not the purpose of Packer, since that would not be repeatable.

Instead just follow the AWS documentation for Creating a Windows AMI from a Running Instance .
