SYNOPSIS
gcloud alpha compute instance-groups managed set-instance-template NAME --template=TEMPLATE [--region=REGION     | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) gcloud alpha compute instance-groups managed set-instance-template sets the instance template for an existing managed instance group.

The new template applies to all new instances added to the managed instance group.

To apply the new template to existing instances in the group, use one of the following methods:

  • Update instances using the update-instances command.
  • Recreate instances using the recreate-instances command.
  • Use the rolling-action start-update command.
  • Use the API to set the group's updatePolicy.type to PROACTIVE.

gcloud alpha compute instance-groups managed set-instance-template \
example-managed-instance-group --template=example-global-instance-template

Sets the instance template for the 'example-managed-instance-group' group to a global resource 'example-global-instance-template'.

To use a regional instance template, specify the full or partial URL of the template.
