This API is used to create an AS policy for an AS group or bandwidth.
The difference between the V2 and V1 APIs for creating an AS policy is that V2 supports creating an AS policy for adjusting bandwidth and differentiating scaling resources by their types.
POST /autoscaling-api/v2/{project_id}/scaling_policy
Parameter |
Mandatory |
Type |
Description |
|---|---|---|---|
project_id |
Yes |
String |
Specifies the project ID. |
Parameter |
Mandatory |
Type |
Description |
|---|---|---|---|
scaling_policy_name |
Yes |
String |
Specifies the AS policy name. The name contains only letters, digits, underscores (_), and hyphens (-), and cannot exceed 64 characters. |
scaling_resource_id |
Yes |
String |
Specifies the scaling resource ID, which is the unique ID of an AS group or bandwidth.
|
scaling_resource_type |
Yes |
String |
Specifies the scaling resource type.
|
scaling_policy_type |
Yes |
String |
Specifies the AS policy type.
|
alarm_id |
No |
String |
Specifies the alarm rule ID. This parameter is mandatory when scaling_policy_type is set to ALARM. After this parameter is specified, the value of scheduled_policy does not take effect. After you create an alarm policy, the system automatically adds an alarm triggering activity of the autoscaling type to the alarm_actions field in the alarm rule specified by the parameter value. You can obtain the parameter value by querying Cloud Eye alarm rules. |
scheduled_policy |
No |
scheduled_policy object |
Specifies the periodic or scheduled AS policy. This parameter is mandatory when scaling_policy_type is set to SCHEDULED or RECURRENCE. After this parameter is specified, the value of alarm_id does not take effect. For details, see Table 3. |
scaling_policy_action |
No |
scaling_policy_action object |
Specifies the scaling action of the AS policy. For details, see Table 4. |
cool_down_time |
No |
Integer |
Specifies the cooldown period (in seconds). The value ranges from 0 to 86400 and is 300 by default. |
description |
No |
String |
Specifies the description of the AS policy. The value can contain 1 to 256 characters. |
Parameter |
Mandatory |
Type |
Description |
|---|---|---|---|
launch_time |
Yes |
String |
Specifies the time when the scaling action is triggered. The time format complies with UTC.
|
recurrence_type |
No |
String |
Specifies the periodic triggering type. This parameter is mandatory when scaling_policy_type is set to RECURRENCE.
|
recurrence_value |
No |
String |
Specifies the day when a periodic scaling action is triggered. This parameter is mandatory when scaling_policy_type is set to RECURRENCE.
|
start_time |
No |
String |
Specifies the start time of the scaling action triggered periodically. The time format complies with UTC. The default value is the local time. The time format is YYYY-MM-DDThh:mmZ. |
end_time |
No |
String |
Specifies the end time of the scaling action triggered periodically. The time format complies with UTC. This parameter is mandatory when scaling_policy_type is set to RECURRENCE. When the scaling action is triggered periodically, the end time cannot be earlier than the current and start time. The time format is YYYY-MM-DDThh:mmZ. |
Parameter |
Mandatory |
Type |
Description |
|---|---|---|---|
operation |
No |
String |
Specifies the operation to be performed. The default operation is ADD.
|
size |
No |
Integer |
Specifies the operation size. The value is an integer from 0 to 300. The default value is 1. This parameter can be set to 0 only when operation is set to SET.
|
percentage |
No |
Integer |
Specifies the percentage of instances to be operated. If operation is set to ADD, REMOVE, or REDUCE, the value of this parameter is an integer from 1 to 20000. If operation is set to SET, the value is an integer from 0 to 20000.
|
limits |
No |
Integer |
Specifies the operation restrictions. If scaling_resource_type is set to BANDWIDTH and operation is not SET, this parameter takes effect and the unit is Mbit/s.
