CreateInstances

1. API Description

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

Prerequisites

• Query stock: call DescribeAvailableResources to check available resources.

• Query instance model: call DescribeInstanceTypes to check specifications.

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

• Cost estimation: know of bare metal cloud pricing. See Billing Method for more details.

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 CREATING during the creation. You can use DescribeInstances to query the status of the instance. If the status changes from PENDING or Creating to Running, it means that the instance has been created successfully; CREATE_FAILED 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.
instanceTypeId	Yes	String	Instance model ID. To view specific values, you can call DescribeInstanceTypes.
imageId	No	String	Valid image ID. To obtain valid image ID, you can call DescribeImages , pass in instanceTypeId to retrieve the list of images supported by the current model, and then find the imageId in the response. You can also not specify an image and install it later through IPMI. When using iPXE to install OS, pass the value of ipxeUrl, and leave imageId empty.
ipxeUrl	No	String	iPXE URL. Pass in the value and install your OS via IPMI. You can choose to install OS using Netboot. See Deploy a Custom Image Using iPXE for more details.
resourceGroupId	No	String	Resource group ID where the instances reside
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].
hostname	No	String	Instance hostname. Default value: hostname. 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].
amount	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 uppercase letters, lowercase letters, numbers and special characters like 1~!@$^*-_=+. This password is also used as the password for IPMI login. Please keep it safe. You must and can only pass the value of either password or sshKeys.
sshKeys	No	Array of String	List of SSH keys. If an SSH key is used to log in, password login will be disabled. Up to 5 keys are supported. Note: For instances of Windows and EXSi operating systems, ignore this parameter. Default value is empty. Even if this parameter is filled in, only the value of password will be passed in. If imageId is not specified, then sshKeys will be ignored. You must and can only pass the value of either password or sshKeys.
internetChargeType	Yes	String	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	No	String	Subnet ID. Call DescribeVpcSubnets to check information on subnets created.
raidConfig	No	RaidConfig	Disk array configuration.
partitions	No	Array of Partition	Disk partition configuration. If the operating system is not installed, the partition cannot be set.
nic	No	Nic	NIC configuration.
enablePrimaryIPv6	No	Boolean	Enable primary IPv6 or not. If the value is false, the primary IPv6 is not enabled and the elastic IPv6 cannot be configured. The default value is true.

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 CREATING during the creation. You can call DescribeInstances to query the status of the instance according to dataSet. If the status changes from PENDING or Creating to Running, it means that the instance has been created successfully; CREATE_FAILED means the instance has been created failed.
orderNumber	String	Number of order.
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
