Hashicorp Packer is a great tool for building Amazon Machine Images. However, sometimes the virtual machine running packer is not stopped. This utility stops or terminated all virtual machines with the name tag 'Packer Builder'
You can use it as a command line utility or install it as an AWS Lambda function and stop the spend , NoOps style!
Since Packer version 1.0.9 the default name tag "Packer Builder" was removed. To make the utility work for your builders, add a run_tags block to the Packer builder spefification:
source "amazon-ebs" "ubuntu" {
name = "my_ubuntu"
...
run_tags = {
Name = "Packer Builder"
}
to install the packer reaper, type:
pip install aws-hashicorp-packer-reaper
To show running packer instances:
$ aws-hashicorp-packer-reaper list

$ aws-hashicorp-packer-reaper stop --older-than 2h
INFO: stopping i-035ebe427a538c829 (Packer Builder) created 2 hours ago
INFO: total of 1 running instances stopped

To deploy the packer reaper as an AWS Lambda, type:
git clone https://github.com/binxio/aws-hashicorp-packer-reaper.git
cd aws-hashicorp-packer-reaper
aws cloudformation deploy \
--capabilities CAPABILITY_IAM \
--stack-name aws-hashicorp-packer-reaper \
--template-file ./cloudformation/aws-hashicorp-packer-reaper.yaml
This will install the packer reaper in your AWS account and run every hour, stopping packer instances launched more than 2 hours ago and terminate instances older than 24 hours. You can change the schedule and the action to meet your requirements.
