Version

v1.0.1

Overview

EBS volumes attached to stopped instances still incur costs even though they may not be used; these should be reviewed and either detached from the stopped instance or deleted.

This query trigger detects EBS volumes attached to stopped instances and then either sends a notification or attempts to perform a predefined corrective action.

Getting Started

By default, this trigger is disabled, however it can be configured by setting the below variables

ebs_volumes_attached_to_stopped_instances_trigger_enabled should be set to true as the default is false.
ebs_volumes_attached_to_stopped_instances_trigger_schedule should be set to your desired running schedule
ebs_volumes_attached_to_stopped_instances_default_action should be set to your desired action (i.e. "notify" for notifications or "detach_volume" to detach the volume from the instance).

Then starting the server:

flowpipe server

or if you've set the variables in a .fpvars file:

flowpipe server --var-file=/path/to/your.fpvars
