Deallocate And Delete Unapproved Azure VMs

Lists Azure VMs with a specific Tag values and checks them against the Approved List. If a VM with the desired Tag value is in running state and unapproved then it is deallocated. If a VM with the desired Tag value is in stopped/deallocated state and unapproved then it is deleted. For the deleted VMs, a Zendesk ticket is raised.

If run with flowpipe server, this mod will run the scan every day at 9 AM UTC.

Docker daemon must be installed and running. Please see Install Docker Engine for more information.

Usage

Run the pipeline to run the scan immediately:

To run the scan at the scheduled time, start the Flowpipe server:

flowpipe server

Once started, Flowpipe will run the pipeline automatically at the scheduled time.
