Call RunInstances API to batch create ECS instances - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service

Creates multiple ECS instances in a batch, with support for automatic startup, public IP address assignment, and automatic release time configuration.

Operation description

Before using this operation, make sure you understand the billing methods and [pricing](https://www.alibabacloud.com/zh/pricing-calculator#/commodity/vm_intl) of ECS.

This operation is asynchronous. After a successful request, the instance IDs are returned. The instances are not created and started immediately. You can call DescribeInstanceStatus to query the instance status. When the status returned is Running, the instances are created and started successfully.

Before you begin

If resources are insufficient to complete the instance creation, Alibaba Cloud immediately sends an instance creation failure event (SystemFailure.Delete). You can call DescribeInstanceHistoryEvents to check for instance creation failure events. For more information, see Instance creation failure events.
Make sure the total number of instances you create or the total number of vCPUs across all instance types does not exceed your quota. For more information, see Quota Center.
Before creating a VPC-type ECS instance, create a VPC in the corresponding Alibaba Cloud region.

Precautions

If the billing method is subscription (PrePaid), active coupon are applied by default at the time of payment.
A single request can create up to 100 instances. If you need to create more than 100 instances, send multiple requests in batches or concurrently.
If the value of the InternetMaxBandwidthOut parameter is greater than 0, a public IP address is automatically allocated to the instance.

Note

The total peak public bandwidth for pay-by-bandwidth instances under a single Alibaba Cloud account in a single region is subject to limits. For more information, see Public bandwidth limits.

Usage recommendations

Testing: Send a dry run request by setting DryRun=true.
Releasing instances: Set the automatic release time using the AutoReleaseTime parameter, or invoke DeleteInstances to perform manual release.
Management and retrieve: Assign tags (Tag.N.Key and Tag.N.Value) to each batch of instances, and add sequential suffixes (UniqueSuffix) to hostnames (HostName) and instance names (InstanceName). For more information, see Set sequential instance names or hostnames in batch.
Launch templates: Use a launch template to avoid specifying a large number of configuration parameters each time you create an instance. Invoke CreateLaunchTemplate to create a launch template, then specify LaunchTemplateId and LaunchTemplateVersion in the RunInstances request to use the template.
Disabling hyper-threading: In memory-intensive workloads, set CpuOptions.ThreadsPerCore=1 to disable hyper-threading and improve the memory-to-CPU ratio.
Enabling jumbo frames: Set NetworkOptions.EnableJumboFrame=true to enable the Jumbo frame attribute at instance creation. For more information, see ECS instance MTU.

Request examples

Suppose you want to create ECS instances in the China (Hangzhou) region using a specific image, instance type, security group, and vSwitch, with a configured system disk and data disk, a public IP address, and a specified instance name and password. The relevant request parameters are as follows:

RegionId:"cn-hangzhou", // Set the China (Hangzhou) region
ImageId:"aliyun_3_x64_20G_alibase_20221102.vhd", // Set the image ID
InstanceType:"ecs.g7.large", // Set the instance type
SecurityGroupId:"sg-bp150uqocpf9jj70****", // Set the security group ID
VSwitchId:"vsw-bp1qo7s91cbch5i4l****", // Set the vSwitch ID
SystemDisk:{
  Category:"cloud_essd", // Set the system disk type to enterprise SSD
  Size:40, // Set the system disk size to 40 GiB
},
DataDisk:[
  {
    Category:"cloud_essd", // Set the data disk type to enterprise SSD
    Size:100, // Set the data disk size to 100 GiB
  }
],
HostName:"ECS-test", // Set the instance hostname
Password:"ECS@test1234", // Set the instance logon password
InternetMaxBandwidthOut:10 // Set the outbound public bandwidth to 10 Mbit/s

Based on the above configuration, create different types of instances:

Example: Create 5 subscription instances with auto-renewal

Amount:5, // number of instances: 5
InstanceChargeType:"PrePaid", // billing method: subscription
PeriodUnit:"Month", // billing cycle unit: month
Period:1, // billing cycle: 1 month
AutoRenew:true, // enable auto-renewal
AutoRenewPeriod:1 // renewal period: 1 month

Example: Create 10 pay-as-you-go instances

Amount:10, // number of instances: 10
InstanceChargeType:"PostPaid", // billing method: pay-as-you-go
SpotStrategy:"NoSpot" // default value, Normal pay-as-you-go

Example: Create 20 spot instances with a bidding policy and retention period

Amount:20, // number of instances: 20
InstanceChargeType:"PostPaid",
SpotStrategy:"SpotAsPriceGo", // bidding policy: automatically bid at the current marketplace price
SpotDuration:1 // spot instance retention period: 1 hour

Suppose you have already created a launch template using CreateLaunchTemplate and want to use it to create ECS instances in the China (Hangzhou) region. The example is as follows:

Example: Create 10 ECS instances from a launch template

RegionId:"cn-hangzhou", // China (Hangzhou) region
Amount:10, // number of instances: 10
LaunchTemplateId:"lt-bp14xczpoxvb6rre****" // launch template ID

Important If both instance parameters and template parameters are specified, the instance parameters take precedence. For example, if the template uses subscription as the billing method but InstanceChargeType is set to PostPaid, the created instances use pay-as-you-go billing.

Example: Create 1 instance using a full image (an ECS instance backup that includes both the system disk and data disks)

RegionId:"cn-hangzhou", // China (Hangzhou) region
ImageId = m-bp13ohd32cvzpq9e****, // custom image ID
InstanceType = ecs.u1-c1m1.large, // instance type
SecurityGroupId = sg-bp10jztp6b0sdsyl****, // security group ID
VSwitchId = vsw-bp19wo63nleroq22g****, // vSwitch ID
SystemDisk.Size = 50, // system disk size included in the full image
SystemDisk.Category = cloud_auto, // disk type of the system disk included in the full image
DataDisk.1.Device = /dev/xvdb, // attach point of the data disk included in the full image
DataDisk.1.Size = 50, // size of the data disk included in the full image
DataDisk.1.Category = cloud_essd, // disk type of the data disk included in the full image
DataDisk.2.Device = /dev/xvdc, // attach point of the additional data disk. To replace the data disk included in the full image with the additional data disk, set DataDisk.1.Device = /dev/xvdb (the default attach point of the data disk in the full image).
DataDisk.2.Size = 70, // size of the additional data disk
DataDisk.2.Category = cloud_auto, // disk type of the additional data disk

SecurityOptions.TrustedSystemMode	string	No	The trusted system mode. Set the value to vTPM. The trusted system mode currently supports the following instance families: g7, c7, r7. Enhanced instance families (g7t, c7t, r7t). When you create an ECS instance of the above instance families, configure this parameter as follows: To use the Alibaba Cloud Trusted System, set this parameter to vTPM. The trusted system then performs a trusted verification when the instance starts. If you do not use the Alibaba Cloud Trusted System, you can leave this parameter unset. However, if the ECS instance uses Enclave confidential computing mode (`SecurityOptions.ConfidentialComputingMode=Enclave`), the trusted system is also enabled for the instance. To create a trusted instance by calling an API operation, invoke `RunInstances`. `CreateInstance` does not support the `SecurityOptions.TrustedSystemMode` parameter. Note If you specify an instance as a trusted instance at creation time, you can only use images that support the trusted system when you replace the system disk. For more information about the trusted system, see Overview of the trusted feature for security-enhanced instances.	vTPM
SecurityOptions.ConfidentialComputingMode	string	No	The confidential computing mode. Set the value to Enclave. When this parameter is set to Enclave, the ECS instance uses Enclave to build a confidential computing environment. Currently, only instance types in instance families c7, g7, and r7 support setting this parameter when invoking `RunInstances`. Note the following: The confidential computing feature is in invitational preview. To create an ECS instance with Enclave confidential computing by calling an API operation, invoke `RunInstances`. `CreateInstance` does not support the `SecurityOptions.ConfidentialComputingMode` parameter. Enclave confidential computing relies on the trusted system (vTPM). When you configure an ECS instance to use Enclave for confidential computing, the trusted system is also enabled for the instance. If you set `SecurityOptions.ConfidentialComputingMode=Enclave` when calling this operation, the created ECS instance enables both Enclave confidential computing pattern and the trusted system, regardless of whether you set `SecurityOptions.TrustedSystemMode=vTPM`. For more information about confidential computing, see Build a confidential computing environment by using Enclave.	Enclave

You can call DescribeInstanceTypes to query the `MaximumQueueNumberPerEni` and `TotalEniQueueQuantity` fields for the instance type. If `NetworkInterface.N.InstanceType` is set to `Primary` and this parameter is set, you cannot set `NetworkInterfaceQueueNumber`.	8
QueuePairNumber	integer	No	The number of queue pairs for the RDMA ENI. If you want to attach multiple RDMA ENIs to the instance, set QueuePairNumber for each ENI based on the maximum QueuePairNumber supported by the instance type and the number of ENIs you plan to use. Make sure the total QueuePairNumber across all ENIs does not exceed the maximum allowed for the instance type. Call DescribeInstanceTypes to query the limit for the instance type. Important If QueuePairNumber is not specified for an RDMA ENI, the maximum QueuePairNumber supported by the instance type is used by default. Therefore, once you attach an RDMA ENI without specifying QueuePairNumber, you cannot attach additional RDMA ENIs (this restriction does not apply to standard ENIs).	0
