CreateInstances

1. API Description

This API is used to create one or more virtual machine instances with a specified configuration.

Prerequisites

• Query instance model: call DescribeZoneInstanceConfigInfos to check specifications.

• Query image: call DescribeImages to check information on image.

Note

• After an instance is created successfully, it will start up automatically, and the instance status will become "RUNNING".

• If you create a subscription instance, the amount required will be pre-deducted. If the balance is insufficient, the request will fail. If you create a pay-as-you-go instance, please ensure your account balance is sufficient before calling this API.

• Vouchers can be used for fee deduction in instance creation. See Vouchers for more details.

• This API is an async API. An instance ID list is returned after the creation request is sent. However, it does not mean the creation has been completed. The status of the instance will be PENDING or DEPLOYING during the creation. You can use DescribeInstances to query the status of the instance. If the status (instanceStatus) changes from PENDING or DEPLOYING to Running, it means that the instance has been created successfully; if no instance has been queried, it means the instance has been created failed. Any operations on the instances are not allowed while creating.

• A maximum of 100 instances can be created in one request.

2. Input Parameters

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
zoneId	Yes	String	Zone ID to which the instances belong.
instanceChargeType	Yes	String	Instance pricing model. PREPAID: subscription POSTPAID: pay-as-you-go.
instanceChargePrepaid	No	ChargePrepaid	Details of the monthly subscription, including the purchase period, auto-renewal. It is required if the instanceChargeType is PREPAID.
instanceType	Yes	String	Instance model ID. To view specific values, you can call DescribeZoneInstanceConfigInfos.
imageId	Yes	String	Valid image ID. To obtain valid image ID, you can call DescribeImages, and find imageId in the response.
resourceGroupId	No	String	Resource group ID where the instances reside. If the value is empty, the instance will be added into the default resource group.
instanceName	No	String	Instance name to be displayed. Default value: instance. This parameter can contain up to 64 characters. Only letters, numbers, - and periods (.) are supported. If you purchase multiple instances at the same time, you can specify a pattern string [begin_number,bits]. begin_number: the starting value of an ordered number, value range: [0,99999], default value: 0. bits: the number of digits occupied by an ordered value, value range: [1,6], default value: 6. For example, if you purchase 1 instance and the instance name body is server_[3,3], the instance name will be server003; if you purchase 2 instances, the instance names will be server003, server004. Note: Spaces are not supported in the pattern string. Multiple pattern strings are supported, such as server_[3,3]_[1,1].
instanceCount	No	Integer	The number of instances to be purchased. Value range: [1,100]. Default value: 1.
password	No	String	Instance password. The parameter must be 8-16 characters, including: lowercase letters: [a-z] uppercase letters: [A-Z] digits: 0-9 special characters: !@#$%^&*`~()-+= You must and can only pass the value of either password or keyId.
keyId	No	String	SSH key pair ID. Your SSH key pair contains several public keys that can be placed on your server. You can access your instance with the private key. SSH key pairs and passwords cannot to set at the same time. SSH key pairs are not supported for Windows operating system. For example: key-YWD2QFOl You must and can only pass the value of either password or keyId.
internetChargeType	Yes	String	Public network pricing model. See InternetChargeType for details.
internetMaxBandwidthOut	No	Integer	Public network bandwidth cap (Mbps). Default value: 1 Mbps. The parameter value differs with different instance models. See bandwidth configuration for details.
trafficPackageSize	No	Float	Traffic package size (TB). The parameter is valid only when internetChargeType is ByTrafficPackage. If not passed in, the default value will be the size of the free traffic package.
subnetId	Yes	String	Subnet ID.
systemDisk	No	SystemDisk	System disk configuration. If the value is empty, the system disk size is the minimum default value to store the operating system.
dataDisks	No	Array of DataDisk	Data disk configuration. If the value is empty, no data disk is attached by default. Only 10 data disk can be attached along with the instance for now.
securityGroupId	No	String	Security group ID. To obtain security group ID, you can call DescribeSecurityGroups , and find sgId in the response.

3. Output Parameters

Parameter Name	Type	Description
instanceIdSet	Array of String	List of instance IDs. The returned instance ID list does not mean the creation has been completed. The status of the instance will be PENDING or DEPLOYING during the creation. You can call DescribeInstances to query the status of the instance according to dataSet. If the status changes from PENDING or DEPLOYING to RUNNING, it means that the instance has been created successfully; CREATE_FAILED or no instance found means the instance has been created failed.
orderNumber	String	Number of order.
instances	Array of DiskWithInstance	Set of data disk IDs created along with the instances. If no data disk is specified, the value is empty.
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
