Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation

Request parameters

Parameter	Type	Required	Description	Example
AppId	string	Yes	The ID of the application.	74ee**-db65-4322-a1f6-bcb60e5b**
GroupId	string	Yes	The ID of the instance group to which the application is deployed.	8123db90-880f-486f-**-**********
InCondition	string	No	The relationship among the conditions that trigger a scale-in. OR: one of the conditions AND: all conditions	"OR"
InEnable	boolean	No	Specifies whether to allow scale-ins. true: allows scale-ins. false: does not allow scale-ins.	true
InCpu	integer	No	The CPU utilization that triggers a scale-in.	50
InDuration	integer	No	The duration in which the metric threshold is exceeded. Unit: minutes.	50
InInstanceNum	integer	No	The minimum number of instances that must be retained in each group when a scale-in is performed.	3
InLoad	integer	No	The system load that triggers a scale-in.	50
InRT	integer	No	The minimum service latency that triggers a scale-in. The lower limit is 0. Unit: milliseconds.	50
InStep	integer	No	The number of instances that are removed during each scale-in.	1
OutCondition	string	No	The relationship among the conditions that trigger a scale-out. OR: one of the conditions AND: all conditions	"OR"
OutCPU	integer	No	The CPU utilization that triggers a scale-out.	50
OutDuration	integer	No	The duration in which the metric threshold is exceeded. Unit: minutes.	50
OutEnable	boolean	No	Specifies whether to allow scale-outs.	true
OutInstanceNum	integer	No	The maximum number of instances in each group when a scale-out is performed.	10

OutRT	integer	No	The minimum service latency that triggers a scale-out. The lower limit is 0. Unit: milliseconds.	0
OutStep	integer	No	The number of instances that are added during each scale-out.	0
ResourceFrom	string	No	The source of the instance to be added during a scale-out. Valid values: NEW: elastic resources AVAILABLE: existing resources If you prefer existing resources to elastic resources, set this parameter to AVAILABLE_FIRST. If you set this parameter to NEW or AVAILABLE_FIRST, you must specify the auto-scaling parameters. If you set this parameter to NEW, instances are created based on a launch template or the specifications of an existing instance.	"AVAILABLE"
MultiAzPolicy	string	No	The multi-zone scaling policy. Valid values: PRIORITY: The vSwitch that is first selected has the highest priority. BALANCE: This policy evenly distributes instances across zones in which the vSwitches reside.	"PRIORITY"
VpcId	string	No	The ID of the virtual private cloud (VPC) that is associated with the instances created based on a launch template or the specifications of an existing instance.	"vpc-bp1j55oz3bg*****"
VSwitchIds	string	No	The IDs of the vSwitches that are associated with the VPC. Separate multiple IDs with commas (,).	"vsw-bp1ldxs3d4fd*****"
ScalingPolicy	string	No	The instance handling mode during a scale-in. Valid values: release: When a scale-in is performed, instances that are no longer used are released. recycle: When a scale-in is performed, instances that are no longer used are stopped and reclaimed.	"release"
TemplateInstanceId	string	No	The ID of the instance whose specifications are used to create instances during a scale-out. This parameter is valid only when you set the OutEnable parameter to true.	"1"
TemplateInstanceName	string	No	The name of the instance whose specifications are used to create instances during a scale-out. This parameter takes effect only if you specify the TemplateInstanceId parameter.	"tpl-tdy218"
Password	string	No	The password that is used to log on to the instance. This parameter takes effect only if you choose to create instances based on the specifications of an existing instance during a scale-out.	"Pwd*****"
KeyPairName	string	No	The key pair that is used to log on to the instance. This parameter takes effect only if you choose to create instances based on the specifications of an existing instance during a scale-out.	"tdy218"
AcceptEULA	boolean	No	Set the value to true if scale-outs are allowed.	true
TemplateId	string	No	The ID of the launch template that is used to create instances during a scale-out. This parameter takes effect only if you set the OutEnable parameter to true. This parameter takes precedence over the TemplateInstanceId parameter.	"lt-wz9hkhn8wp*****"
TemplateVersion	integer	No	The version of the launch template that is used to create instances during a scale-out. This parameter takes effect only if you set the OutEnable parameter to true. To use the default template version, set this parameter to `-1`. Otherwise, set this parameter to the version that you want to use.	-1
