RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Path Parameters

Parameter	Type	Required	Description	Example
serviceName	string	Yes	The service name.	demoService
functionName	string	Yes	The function name.	demoFunction

Request parameters

Parameter	Type	Required	Description	Example
qualifier	string	Yes	The service alias or LATEST. Versions are not supported.	prod
body	object	No	The configuration of provisioned instances.
target	integer	Yes	The target number of provisioned resources. Valid values: 0 to 10000.	1
scheduledActions	array	No	The scheduled scaling policy configuration.
	ScheduledActions	No	The specific configuration of the scheduled scaling policy.
targetTrackingPolicies	array	No	The metric tracking scaling policy configuration.
	TargetTrackingPolicies	No	The specific configuration of the metric tracking scaling policy.
alwaysAllocateCPU	boolean	No	Specifies whether to always allocate CPU. Default value: true.	true
X-Fc-Account-Id	string	No	The ID of your Alibaba Cloud account.	188077086902****
X-Fc-Date	string	No	The start date of the function invocation. The format is EEE,d MMM yyyy HH:mm:ss GMT.	Wed, 11 May 2022 09:00:00 GMT

Response elements

Element	Type	Description	Example
	object	The details of the provisionConfig configuration.
resource	string	The resource description.	"12345#servierName#qualifier#functionName"
target	integer	The target number of resources.	5
current	integer	The actual number of resources.	1
scheduledActions	array	The scheduled scaling policy configuration.
	ScheduledActions	The scheduled scaling policy. You can use scheduled scaling policies to flexibly configure provisioned function instances by setting the number of provisioned function instances to a desired value at a specified time. This allows the number of function instances to better match the concurrency of your workloads.	[ { "Name": "action_1", "StartTime": "2020-11-01T10:00:00Z", "EndTime": "2020-11-30T10:00:00Z", "TargetValue": 50, "ScheduleExpression": "cron(0 0 20 * * )" }, { "Name": "action_2", "StartTime": "2020-11-01T10:00:00Z", "EndTime": "2020-11-30T10:00:00Z", "TargetValue": 10, "ScheduleExpression": "cron(0 0 22 * *)" } ]
targetTrackingPolicies	array	The metric tracking scaling policy configuration.
	TargetTrackingPolicies	The metric tracking scaling policy. This policy scales provisioned resources once per minute based on the concurrency utilization of function instances. When the metric exceeds the tracking value metricTarget, an aggressive scale-out policy is applied to increase the number of provisioned function instances so that the metric returns to near the metricTarget value. When the metric falls below the tracking value metricTarget, a conservative scale-in policy is applied to decrease the number of provisioned function instances so that the metric gradually returns to near the metricTarget value. If you set a maximum value and a minimum value for scaling in the system, the number of provisioned function instances scales between the maximum and minimum values. Scale-out stops when the maximum value is exceeded, and scale-in stops when the number falls below the minimum value.	[ { "Name": "action_1", "StartTime": "2020-11-01T10:00:00Z", "EndTime": "2020-11-30T10:00:00Z", "MetricType": "ProvisionedConcurrencyUtilization", "MetricTarget": 0.6, "MinCapacity": 10, "MaxCapacity": 100, } ]
alwaysAllocateCPU	boolean	Indicates whether CPU is always allocated to function instances.	true
