Packer builder plugin that allows to AMI from empty volume.

{
  "type": "amazon-scratch",
  "region": "ap-northeast-1",
  "source_ami": "ami-936d9d93",
  "subnet_id": "subnet-XXX",
  "associate_public_ip_address": true,
  "instance_type": "t2.micro",
  "ssh_username": "ubuntu",
  "ami_name": "packer {{timestamp}}",
  "worker_device_name": "/dev/sdf",
  "volume_size": 4,
  "volume_type": "gp2"
}

this will starts instance with 4GB gp2 EBS, using ami-936d9d93. Then provision your stuff on /dev/sdf.

Finally /dev/sdf will be used as root block device on new AMI.

Difference with amazon-chroot

• amazon-chroot doesn't allow do something on host machine -- it runs all commands in chrooted environment.
• amazon-chroot requires run packer on an existing EC2 instance, but this doesn't.
• this launches source_ami to create AMI, each time.
• this creates empty EBS. amazon-chroot always requires source AMI as base.
