Delete a MIG

This document describes how to delete a managed instance group (MIG) that you no longer need so you can stop paying for the resources it uses.

Before you begin

Delete a MIG

When you delete a managed instance group, all VMs in the group are deleted. If you want to keep any of the VMs, abandon the VMs first to remove those VMs from the group. Then, delete the managed instance group.

The disks in a MIG are deleted only if you had set the disk's auto-delete property to true when defining the disks in the MIG's instance template. If a disk's auto-delete property is set to false, then you can manually clean up the disks when you no longer need them.

When you delete a managed instance group and its instances by using the Google Cloud console or the gcloud CLI, any attached autoscalers are automatically deleted. However, if you use the Compute Engine API, you must first issue separate requests to delete any attached autoscalers with the autoscalers.delete method or regionAutoscalers.delete method.

For each disk, you can also override the auto-delete property to specify whether the disk should be deleted when its associated instance is deleted.

Console

  1. In the Cloud console, go to the Instance groups page.

    Go to Instance groups

  2. Select one or more groups on the list that you want to delete.

  3. Click Delete to delete the group and all of the VMs in the managed instance group.

gcloud

Use the delete command.

gcloud compute instance-groups managed delete INSTANCE_GROUP_NAME \
    --zone ZONE

API

Call the delete method for a zonal or regional MIG resource.

DELETE https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instanceGroupManagers/INSTANCE_GROUP_NAME

If the instance group is a regional managed instance group, replace zones/ZONE with regions/REGION.
