lambder-create-images

create-images is an AWS Lambda function for use with Lambder.

REQUIRES:

• python-lambder

This lambda function creates an Amazon Machine Image from each EC2 instance tagged with Key: 'LambderBackup'. By default, instances will not be rebooted during the image creation process. The function will retain at most 3 images and delete the oldest images to stay under this threshold.

Installation

1. Clone this repo
2. cp example_lambder.json lambder.json
3. Edit lambder.json to set your S3 bucket
4. lambder functions deploy

Usage

Schedule the function with a new event. Rember that the cron expression is based on UTC.

lambder events add \
  --name CreateImages \
  --function-name Lambder-create-images \
  --cron 'cron(0 6 ? * * *)'

TODO

• Parameterize the tag in the input event object
• Parameterize number of old images to retain
• Parameterize no-reboot option
