dateOlderThan for EC2 instances and other resource

[nmiculinic]

Maybe I've misread the docs....though I want to kill all EC2 instances older than 2h for example. (among other resources).

Can I achieve this with this tool, or is it not in the feature set.

@nmiculinic I was trying to do something very similar today and also couldn't figure out how to do it. After spelunking in the code, I found that for EC2 instances, the launchTime metadata is not populated into the properties for that resource -- which means that at the moment, there doesn't appear to be any easy way to nuke EC2 instances that are >= X hours old.

Ref:

aws-nuke/resources/ec2-instances.go

Line 109 in b5ccc00

func (i *EC2Instance) Properties() types.Properties {

This looks pretty useful and easy to add, so hopefully it'll be fixed relatively easily. If I have a few moments, I might open a PR to fix it myself.

I implemented the necessary properties to underly this behaviour and have submitted them in #670. After that PR has been merged, this will be possible with a filter statement like this:

      EC2Instance:
      - property: "LaunchTime"
        type: dateOlderThan
        value: "2h"
