The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
Parameter Name | Required | Type | Description |
---|---|---|---|
Action | Yes | String | Common Params. The value used for this API: CreateAutoScalingGroup. |
Version | Yes | String | Common Params. The value used for this API: 2018-04-19. |
Region | Yes | String | Common Params. For more information, please see the list of regions supported by the product. |
AutoScalingGroupName | Yes | String | Auto scaling group name, which can only contain letters, numbers, underscores, hyphens ("-"), and decimal points with a maximum length of 55 bytes and must be unique under your account. |
LaunchConfigurationId | Yes | String | Launch configuration ID |
MaxSize | Yes | Integer | Maximum number of instances. Value range: 0-2,000. |
MinSize | Yes | Integer | Minimum number of instances. Value range: 0-2,000. |
VpcId | Yes | String | VPC ID; if on a basic network, enter an empty string |
DefaultCooldown | No | Integer | Default cooldown period in seconds. Default value: 300 |
DesiredCapacity | No | Integer | Desired number of instances. The number should be no larger than the maximum and no smaller than minimum number of instances |
LoadBalancerIds.N | No | Array of String | List of classic CLB IDs. Currently, the maximum length is 20. You cannot specify LoadBalancerIds and ForwardLoadBalancers at the same time. |
ProjectId | No | Integer | Project ID of an instance in a scaling group. The default project is used if it’s left blank. |
ForwardLoadBalancers.N | No | Array of ForwardLoadBalancer | List of application CLBs. Up to 100 CLBs are allowed. LoadBalancerIds and ForwardLoadBalancers cannot be specified at the same time. |
SubnetIds.N | No | Array of String | List of subnet IDs. A subnet must be specified in the VPC scenario. If multiple subnets are entered, their priority will be determined by the order in which they are entered, and they will be tried one by one until instances can be successfully created. |
TerminationPolicies.N | No | Array of String | Termination policy. Currently, the maximum length is 1. Value range: OLDEST_INSTANCE, NEWEST_INSTANCE. Default value: OLDEST_INSTANCE. |
Zones.N | No | Array of String | List of availability zones. An availability zone must be specified in the basic network scenario. If multiple availability zones are entered, their priority will be determined by the order in which they are entered, and they will be tried one by one until instances can be successfully created. |
RetryPolicy | No | String | Retry policy. Valid values: IMMEDIATE_RETRY (default), INCREMENTAL_INTERVALS , NO_RETRY . A partially successful scaling is judged as a failed one.IMMEDIATE_RETRY : Retry immediately. Stop retrying after five consecutive failures.INCREMENTAL_INTERVALS : Retry at incremental intervals. As the number of consecutive failures increases, the retry interval gradually increases, ranging from seconds to one day.NO_RETRY : Do not retry. Actions are taken when the next call or alarm message comes. |
ZonesCheckPolicy | No | String | Availability zone verification policy. Value range: ALL, ANY. Default value: ANY. Common reasons why an availability zone or subnet is unavailable include stock-out of CVM instances or CBS cloud disks in the availability zone, insufficient quota in the availability zone, or insufficient IPs in the subnet. If an availability zone or subnet in Zones/SubnetIds does not exist, a verification error will be reported regardless of the value of ZonesCheckPolicy. |
Tags.N | No | Array of Tag | List of tag descriptions. In this parameter, you can specify the tags to be bound with a scaling group as well as corresponding resource instances. Each scaling group can have up to 30 tags. |
ServiceSettings | No | ServiceSettings | Service settings such as unhealthy instance replacement. |
Ipv6AddressCount | No | Integer | The number of IPv6 addresses that an instance has. Valid values: 0 and 1. Default value: 0. |
MultiZoneSubnetPolicy | No | String | Multi-availability zone/subnet policy. Valid values: PRIORITY and EQUALITY. Default value: PRIORITY. Notes: |
HealthCheckType | No | String | Health check type of instances in a scaling group. If the parameter is set to CLB , the scaling group will check both the network status and the CLB health check status. If the network check indicates unhealthy, the HealthStatus field will return UNHEALTHY . If the CLB health check indicates unhealthy, the HealthStatus field will return CLB_UNHEALTHY . If both checks indicate unhealthy, the HealthStatus field will return UNHEALTHY|CLB_UNHEALTHY . Default value: CLB . |
LoadBalancerHealthCheckGracePeriod | No | Integer | Grace period of the CLB health check during which the IN_SERVICE instances added will not be marked as CLB_UNHEALTHY .Valid range: 0-7200, in seconds. Default value: 0 . |
InstanceAllocationPolicy | No | String | Specifies how to assign instances. Valid values: LAUNCH_CONFIGURATION and SPOT_MIXED ; default value: LAUNCH_CONFIGURATION .LAUNCH_CONFIGURATION : the launch configuration mode.SPOT_MIXED : a mixed instance mode. Currently, this mode is supported only when the launch configuration takes the pay-as-you-go billing mode. With this mode, the scaling group can provision a combination of pay-as-you-go instances and spot instances to meet the configured capacity. Note that the billing mode of the associated launch configuration cannot be modified when this mode is used. |
SpotMixedAllocationPolicy | No | SpotMixedAllocationPolicy | Specifies how to assign pay-as-you-go instances and spot instances. This parameter is valid only when InstanceAllocationPolicy is set to SPOT_MIXED . |
CapacityRebalance | No | Boolean | Indicates whether the capacity re-balancing feature is enabled. This parameter is only valid for spot instances in the scaling group. Valid values:TRUE : yes. Before the spot instances in the scaling group are about to be automatically repossessed, AS will terminate them. The scale-in hook (if configured) will take effect before the termination. After the termination process starts, AS will asynchronously initiate a scaling activity to meet the desired capacity.FALSE : no. In this case, AS will add instances to meet the desired capacity only after the spot instances are terminated.Default value: False . |
InstanceNameIndexSettings | No | InstanceNameIndexSettings | Instance name sequencing settings. If this parameter is not specified, the default is not enabled. When enabled, an incremental numeric sequence will be appended to the names of instances automatically created within the scaling group. |
Parameter Name | Type | Description |
---|---|---|
AutoScalingGroupId | String | Auto scaling group ID |
RequestId | String | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
This example shows how to create an auto scaling group in a specified VPC and configure a layer-7 load balancer.
