Method: regionInstanceGroupManagers.patch

Updates a managed instance group using the information that you specify in the request. This operation is marked asDONE when the group is patched even if the instances in the group are still in the process of being patched. You must separately verify the status of the individual instances with thelistmanagedinstances method. This method supportsPATCH semantics and uses theJSON merge patch format and processing rules.

If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, seeUpdating instances in a MIG.

Query parameters

Parameters

Parameters
`requestId`	`string` An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a validUUID with the exception that zero UUID is not supported (`00000000-0000-0000-0000-000000000000`).

`distributionPolicy.zones[].zone`	`string` The URL of thezone. The zone must exist in the region where the managed instance group is located.
`distributionPolicy.targetShape`	`enum` The distribution shape to which the group converges either proactively or on resize events (depending on the value set in`updatePolicy.instanceRedistributionType`).
`instanceTemplate`	`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`. Authorization requires one or more of the followingIAM permissions on the specified resource`instanceTemplate`: `compute.instanceTemplates.get` `compute.instanceTemplates.useReadOnly`
`versions[]`	`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 therelationships 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 aboutcanary updates.
`versions[].name`	`string` Name of the version. Unique among all versions in the scope of this managed instance group.
`versions[].instanceTemplate`	`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. Authorization requires one or more of the followingIAM permissions on the specified resource`instanceTemplate`: `compute.instanceTemplates.get` `compute.instanceTemplates.useReadOnly`
`versions[].targetSize`	`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. If unset, this version will update any remaining instances not updated by another`version`. ReadStarting a canary update for more information.
`versions[].targetSize.fixed`	`integer` Specifies a fixed number of VM instances. This must be a positive integer.
`versions[].targetSize.percent`	`integer` Specifies a percentage of instances between 0 to 100%, inclusive. For example, specify`80` for 80%.
`versions[].targetSize.calculated`	`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.
`allInstancesConfig`	`object` Specifies configuration that overrides the instance template configuration for the group.
`allInstancesConfig.properties`	`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.
`allInstancesConfig.properties.metadata`	`map (key: string, value: string)` The metadata key-value pairs that you want to patch onto the instance. For more information, seeProject and instance metadata.
`allInstancesConfig.properties.labels`	`map (key: string, value: string)` The label key-value pairs that you want to patch onto the instance.
`instanceGroup`	`string` [Output Only] The URL of the Instance Group resource.
`targetPools[]`	`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. Authorization requires the followingIAM permission on the specified resource`targetPools`: `compute.targetPools.get`
`baseInstanceName`	`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 withRFC1035 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}(\[[0-9]{1,10}\])?))
`fingerprint`	`string (bytes format)` Fingerprint of this resource. This field may be used in optimistic locking. It will be ignored when inserting an InstanceGroupManager.

`currentActions.creating`	`integer` [Output Only] The number of instances in the managed instance group that are scheduled to be created or are currently being created. If the group fails to create any of these instances, it tries again until it creates the instance successfully. If you have disabled creation retries, this field will not be populated; instead, the`creatingWithoutRetries` field will be populated.
`currentActions.creatingWithoutRetries`	`integer` [Output Only] The number of instances that the managed instance group will attempt to create. The group attempts to create each instance only once. If the group fails to create any of these instances, it decreases the group's`targetSize` value accordingly.

`status.stateful.isStateful (deprecated)`	`boolean` [Output Only] A bit indicating whether the managed instance group has stateful configuration, that is, if you have configured any items in a stateful policy or in per-instance configs. The group might report that it has no stateful configuration even when there is still some preserved state on a managed instance, for example, if you have deleted all PICs but not yet applied those deletions. This field is deprecated in favor of hasStatefulConfig.
`status.stateful.hasStatefulConfig`	`boolean` [Output Only] A bit indicating whether the managed instance group has stateful configuration, that is, if you have configured any items in a stateful policy or in per-instance configs.

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.
`updatePolicy.mostDisruptiveAllowedAction`	`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.

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.
`updatePolicy.maxUnavailable`	`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'sstatus is`RUNNING`. If there is ahealth 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.
