string

Output only. The resource type, which is always compute#instanceGroupManager for managed instance groups.

string (uint64 format)

Output only. A unique identifier for this resource type. The server generates this identifier.

string

Output only. The creation timestamp for this managed instance group in RFC3339 text format.

string

The name of the managed instance group. The name must be 1-63 characters long, and comply with RFC1035.

string

An optional description of this resource.

string

Output only. The URL of a zone where the managed instance group is located (for zonal resources).

string

Output only. The URL of the region where the managed instance group resides (for regional resources).

object

Policy specifying the intended distribution of managed instances across zones in a regional managed instance group.

object

Zones where the regional managed instance group will create and manage its instances. By default, a regional MIG doesn't automatically select an AI zone to create instances, even if an AI zone is available in the specified region. To create instances in an AI zone in the selected region, you must explicitly specify it in the distribution policy together with the other preferred zones.

string

The URL of the zone. The zone must exist in the region where the managed instance group is located.

enum

The distribution shape to which the group converges either proactively or on resize events (depending on the value set in updatePolicy.instanceRedistributionType).

string

The URL of the instance template that is specified for this managed instance group. The group uses this template to create all new instances in the managed instance group. The templates for existing instances in the group do not change unless you run recreateInstances, run applyUpdatesToInstances, or set the group's updatePolicy.type to PROACTIVE.

object

Specifies the instance templates used by this managed instance group to create instances.

Each version is defined by an instanceTemplate and a name. Every version can appear at most once per instance group. This field overrides the top-level instanceTemplate field. Read more about the relationships between these fields. Exactly one version must leave the targetSize field unset. That version will be applied to all remaining instances. For more information, read about canary updates.

string

Name of the version. Unique among all versions in the scope of this managed instance group.

string

The URL of the instance template that is specified for this managed instance group. The group uses this template to create new instances in the managed instance group until the targetSize for this version is reached. The templates for existing instances in the group do not change unless you run recreateInstances, run applyUpdatesToInstances, or set the group's updatePolicy.type to PROACTIVE; in those cases, existing instances are updated until the targetSize for this version is reached.

object

Specifies the intended number of instances to be created from the instanceTemplate. The final number of instances created from the template will be equal to:

• If expressed as a fixed number, the minimum of either targetSize.fixed or instanceGroupManager.targetSize is used.
• if expressed as a percent, the targetSize would be (targetSize.percent/100 * InstanceGroupManager.targetSize) If there is a remainder, the number is rounded.

integer

Specifies a fixed number of VM instances. This must be a positive integer.

integer

Specifies a percentage of instances between 0 to 100%, inclusive. For example, specify 80 for 80%.

integer

Output only. Absolute value of VM instances calculated based on the specific mode.

• If the value is fixed, then the calculated value is equal to the fixed value.
• If the value is a percent, then the calculated value is percent/100 * targetSize. For example, the calculated value of a 80% of a managed instance group with 150 instances would be (80/100 * 150) = 120 VM instances. If there is a remainder, the number is rounded.

object

Specifies configuration that overrides the instance template configuration for the group.

object

Properties to set on all instances in the group.

You can add or modify properties using the instanceGroupManagers.patch or regionInstanceGroupManagers.patch. After setting allInstancesConfig on the group, you must update the group's instances to apply the configuration. To apply the configuration, set the group's updatePolicy.type field to use proactive updates or use the applyUpdatesToInstances method.

map (key: string, value: string)

The metadata key-value pairs that you want to patch onto the instance. For more information, see Project and instance metadata.

map (key: string, value: string)

The label key-value pairs that you want to patch onto the instance.

string

Output only. The URL of the Instance Group resource.

string

The URLs for all TargetPool resources to which instances in the instanceGroup field are added. The target pools automatically apply to all of the instances in the managed instance group.

string

The base instance name is a prefix that you want to attach to the names of all VMs in a MIG. The maximum character length is 58 and the name must comply with RFC1035 format.

When a VM is created in the group, the MIG appends a hyphen and a random four-character string to the base instance name. If you want the MIG to assign sequential numbers instead of a random string, then end the base instance name with a hyphen followed by one or more hash symbols. The hash symbols indicate the number of digits. For example, a base instance name of "vm-###" results in "vm-001" as a VM name. @pattern [a-z](([-a-z0-9]{0,57})|([-a-z0-9]{0,51}-#{1,10}(\[[0-9]{1,10}\])?))

string (bytes format)

Fingerprint of this resource. This field may be used in optimistic locking. It will be ignored when inserting an InstanceGroupManager. An up-to-date fingerprint must be provided in order to update the InstanceGroupManager, otherwise the request will fail with error 412 conditionNotMet.

To create a disk with a custom image that you created, specify the image name in the following format:

global/images/my-custom-image

You can also specify a custom image by its image family, which returns the latest version of the image in that family. Replace the image name with family/family-name:

global/images/family/my-image-family

If the source image is deleted later, this field will not be set.

object

Encrypts or decrypts a disk using a customer-supplied encryption key.

If you are creating a new disk, this field encrypts the new disk using an encryption key that you provide. If you are attaching an existing disk that is already encrypted, this field decrypts the disk using the customer-supplied encryption key.

If you encrypt a disk using a customer-supplied key, you must provide the same key again when you attempt to use this resource at a later time. For example, you must provide the key when you create a snapshot or an image from the disk or when you attach the disk to a virtual machine instance.

If you do not provide an encryption key, then the disk will be encrypted using an automatically generated key and you do not need to provide a key to use the disk later.

Note:

Instance templates do not store customer-supplied encryption keys, so you cannot use your own keys to encrypt disks in a managed instance group.

You cannot create VMs that have disks with customer-supplied keys using the bulk insert method.

boolean

[Input Only] Whether to force attach the regional disk even if it's currently attached to another instance. If you try to force attach a zonal disk to an instance, you will receive an error.

boolean

Output only. Whether to indicate the attached disk is locked. The locked disk is not allowed to be detached from the instance, or to be used as the source of the snapshot creation, and the image creation. The instance with at least one locked attached disk is not allow to be used as source of machine image creation, instant snapshot creation, and not allowed to be deleted with --keep-disk parameter set to true for locked disks.

enum

Output only. The architecture of the attached disk. Valid values are ARM64 or X86_64.

object

Provisioning model configuration used by this managed instance group to create instances.

integer

The base capacity that will always use Standard VMs to avoid risk of more preemption than the minimum capacity user needs. MIG will create only Standard VMs until it reaches standardCapacityBase and only then will start using standardCapacityPercentAboveBase to mix Spot with Standard VMs.

integer

The percentage of target capacity that should use Standard VM. The remaining percentage will use Spot VMs. The percentage applies only to the capacity above standardCapacityBase.

integer

The target number of stopped instances for this managed instance group. This number changes when you:

• Stop instance using the stopInstances method or start instances using the startInstances method.
• Manually change the targetStoppedSize using the update method.

integer

The target number of suspended instances for this managed instance group. This number changes when you:

• Suspend instance using the suspendInstances method or resume instances using the resumeInstances method.
• Manually change the targetSuspendedSize using the update method.

enum

Pagination behavior of the listManagedInstances API method for this managed instance group.

object

Standby policy for stopped and suspended instances.

integer

Specifies the number of seconds that the MIG should wait to suspend or stop a VM after that VM was created. The initial delay gives the initialization script the time to prepare your VM for a quick scale out. The value of initial delay must be between 0 and 3600 seconds. The default value is 0.

enum

Defines how a MIG resumes or starts VMs from a standby pool when the group scales out. The default mode is MANUAL.

string

Output only. The URL for this managed instance group. The server defines this URL.

object

The autohealing policy for this managed instance group. You can specify only one value.

string

The URL for the health check that signals autohealing.

integer

The initial delay is the number of seconds that a new VM takes to initialize and run its startup script. During a VM's initial delay period, the MIG ignores unsuccessful health checks because the VM might be in the startup process. This prevents the MIG from prematurely recreating a VM. If the health check receives a healthy response during the initial delay, it indicates that the startup process is complete and the VM is ready. The value of initial delay must be between 0 and 3600 seconds. The default value is 0.

object

The update policy for this managed instance group.

enum

The type of update process. You can specify either PROACTIVE so that the MIG automatically updates VMs to the latest configurations or OPPORTUNISTIC so that you can select the VMs that you want to update.

enum

The instance redistribution policy for regional managed instance groups. Valid values are:

• PROACTIVE (default): The group attempts to maintain an even distribution of VM instances across zones in the region.
• NONE: For non-autoscaled groups, proactive redistribution is disabled.

enum

Minimal action to be taken on an instance. Use this option to minimize disruption as much as possible or to apply a more disruptive action than is necessary.

• To limit disruption as much as possible, set the minimal action to REFRESH. If your update requires a more disruptive action, Compute Engine performs the necessary action to execute the update.
• To apply a more disruptive action than is strictly necessary, set the minimal action to RESTART or REPLACE. For example, Compute Engine does not need to restart a VM to change its metadata. But if your application reads instance metadata only when a VM is restarted, you can set the minimal action to RESTART in order to pick up metadata changes.

enum

Most disruptive action that is allowed to be taken on an instance. You can specify either NONE to forbid any actions, REFRESH to avoid restarting the VM and to limit disruption as much as possible. RESTART to allow actions that can be applied without instance replacing or REPLACE to allow all possible actions. If the Updater determines that the minimal update action needed is more disruptive than most disruptive allowed action you specify it will not perform the update at all.

object

The maximum number of instances that can be created above the specified targetSize during the update process. This value can be either a fixed number or, if the group has 10 or more instances, a percentage. If you set a percentage, the number of instances is rounded if necessary. The default value for maxSurge is a fixed value equal to the number of zones in which the managed instance group operates.

At least one of either maxSurge or maxUnavailable must be greater than 0. Learn more about maxSurge.

integer

Specifies a fixed number of VM instances. This must be a positive integer.

integer

Specifies a percentage of instances between 0 to 100%, inclusive. For example, specify 80 for 80%.

integer

Output only. Absolute value of VM instances calculated based on the specific mode.

• If the value is fixed, then the calculated value is equal to the fixed value.
• If the value is a percent, then the calculated value is percent/100 * targetSize. For example, the calculated value of a 80% of a managed instance group with 150 instances would be (80/100 * 150) = 120 VM instances. If there is a remainder, the number is rounded.

object

The maximum number of instances that can be unavailable during the update process. An instance is considered available if all of the following conditions are satisfied:

• The instance's status is RUNNING.
• If there is a health check on the instance group, the instance's health check status must be HEALTHY at least once. If there is no health check on the group, then the instance only needs to have a status of RUNNING to be considered available.

This value can be either a fixed number or, if the group has 10 or more instances, a percentage. If you set a percentage, the number of instances is rounded if necessary. The default value for maxUnavailable is a fixed value equal to the number of zones in which the managed instance group operates.

At least one of either maxSurge or maxUnavailable must be greater than 0. Learn more about maxUnavailable.

integer

Specifies a fixed number of VM instances. This must be a positive integer.

integer

Specifies a percentage of instances between 0 to 100%, inclusive. For example, specify 80 for 80%.

integer

Output only. Absolute value of VM instances calculated based on the specific mode.

• If the value is fixed, then the calculated value is equal to the fixed value.
• If the value is a percent, then the calculated value is percent/100 * targetSize. For example, the calculated value of a 80% of a managed instance group with 150 instances would be (80/100 * 150) = 120 VM instances. If there is a remainder, the number is rounded.

integer

Minimum number of seconds to wait for after a newly created instance becomes available. This value must be from range [0, 3600].

enum

What action should be used to replace instances. See minimalAction.REPLACE

object

Output only. Named ports configured on the Instance Groups complementary to this Instance Group Manager.

string

Disks created on the instances that will be preserved on instance delete, update, etc. This map is keyed with the device names of the disks.

enum

These stateful disks will never be deleted during autohealing, update or VM instance recreate operations. This flag is used to configure if the disk should be deleted after it is no longer used by the group, e.g. when the given instance or the whole group is deleted. Note: disks attached in READ_ONLY mode cannot be auto-deleted.

map (key: string, value: object)

External network IPs assigned to the instances that will be preserved on instance delete, update, etc. This map is keyed with the network interface name.

enum

These stateful IPs will never be released during autohealing, update or VM instance recreate operations. This flag is used to configure if the IP reservation should be deleted after it is no longer used by the group, e.g. when the given instance or the whole group is deleted.

object

The repair policy for this managed instance group.

enum

A bit indicating whether to forcefully apply the group's latest configuration when repairing a VM. Valid options are:

• NO (default): If configuration updates are available, they are not forcefully applied during repair. Instead, configuration updates are applied according to the group's update policy.
• YES: If configuration updates are available, they are applied during repair.

enum

The action that a MIG performs on a failed VM. If the value of the onFailedHealthCheck field is DEFAULT_ACTION, then the same action also applies to the VMs on which your application fails a health check. Valid values are - REPAIR (default): MIG automatically repairs a failed VM by recreating it. For more information, see About repairing VMs in a MIG. - DO_NOTHING: MIG does not repair a failed VM.

enum
