o_delete replace the following instance_template_name is the name of the template to create source_instance is the name of the instance to use as a model for the new template source_instance_zone is the zone that contains the source instance source_disk is the name of a source instance disk that you want to override within the template instantiate_options specifies whether to include the disk and which image to use valid values depend on the type of disk source image or source image family valid only for boot and other persistent read write disks specify this option if you want to use the same source image or source image family that was used to create the disk in the source vm instance custom image valid only for boot and other persistent read write disks if you want to retain applications and settings from the source vms in your instance template you can create a custom image and then specify it when you create the template if specified then provide the path or url for the custom image as shown in the following example alternatively you can specify an image family using the following format configure disk device name data_disk_name instantiate from custom image custom image projects project_id global images family image_family_name attach read only valid only for read only disks blank valid only for non boot persistent disks and local ssds if specified then when the template is used to create a new instance the disk is created unformatted you must format and mount the disk in a startup script before you can use it in a scalable setup do not include valid only for non boot persistent disks and read only disks auto_delete specifies whether the disk is auto deleted when the instance is deleted valid values are false no true and yes for example the following command creates an instance template based on my source instance with the option to use the original image from data disk a but set auto delete to true and replace data disk b with a custom image gcloud

instance_template template_name rest to create a regional instance template use the regioninstancetemplates insert method or to create a global instance template use the instancetemplates insert method in your request you must specify the sourceinstance field to override how the source instance s disks are defined add one or more diskconfigs fields for example make the following call to create a global instance template from an existing instance post https compute googleapis com compute v1 projects project_id global instancetemplates name instance_template_name sourceinstance zones source_instance_zone instances source_instance sourceinstanceparams diskconfigs devicename source_disk instantiatefrom instantiate_options autodelete false replace the following project_id your project id instance_template_name the name for the new template source_instance_zone the zone of the source instance source_instance the name of the source instance to use as a model for this instance template source_disk the name of a source instance disk that you want to override within the template instantiate_options specifies whether to include the disk and which image to use valid values depend on the type of disk source image or source image family valid only for boot and other persistent read write disks custom image valid only for boot and other persistent read write disks if you want to retain applications and settings from the source vms in your instance template you can create a custom image and then specify it when you create the template if specified then provide the path or url for the custom image as shown in the following example alternatively you can specify an image family using the following format diskconfigs devicename data_disk_name instantiatefrom custom image customimage projects project_id global images family image_family_name attach read only valid only for read only disks blank valid only for non boot persistent disks and local ssds if specified then when the template is used to create a new instance the disk is created unformatted you must format and mount the disk in a startup script before you can use it in a scalable setup do not include valid only for non boot persistent disks and read only disks the following example creates a new instance template based on my source instance in the instance template the image for data disk a is replaced with projects cos cloud global images cos 89 16108 403 15 post https compute googleapis com compute v1 projects my_project global instancetemplates name my instance template sourceinstance

the following table shows how the options for overriding disks are defined in the template disk type options boot disk default use the same source image or image family that was used to create the boot disk in the source instance use the url of any image custom or public as described in the preceding example or specify an image family using the following format projects exampleproject global images family image_family_name other read write persistent disks default use the same source image source image family that was used to create the disk in the source instance note if the source instance s disk doesn t have a source image source image family property then it is included in the template as a blank disk use the url of any image custom or public as described in the preceding example or specify an image family using the foll...
