reduce

Generic reduce filter to group, sort, and limit your resources.

This example will select the longest running instance from each ASG, then randomly choose 10% of those, maxing at 15 total instances.

example

- name: oldest-instance-by-asg
  resource: ec2
  filters:
    - "tag:aws:autoscaling:groupName": present
    - type: reduce
      group-by: "tag:aws:autoscaling:groupName"
      sort-by: "LaunchTime"
      order: asc
      limit: 1

Or you might want to randomly select a 10 percent of your resources, but no more than 15.

example

- name: random-selection
  resource: ec2
  filters:
    - type: reduce
      order: randomize
      limit: 15
      limit-percent: 10
