RunInstances - API Reference| Alibaba Cloud Documentation Center

Creates one or more pay-as-you-go or subscription Elastic Compute Service (ECS) instances.

Description

Preparations:
- Cost estimation: Learn about the billing methods of ECS resources. For more information, see Billing overview.
- Instance type selection: Call the DescribeInstanceTypes operation to query the performance data of instance types, or learn about how to select instance types. For more information, see Best practices for instance type selection.
- Query for available resources: Call the DescribeAvailableResource operation to query available resources in a specific region or zone.
- Network planning: Make sure that you have security groups available for use. For more information, see CreateSecurityGroup. Before you create an instance of the Virtual Private Cloud (VPC) type, create a VPC in the region where you want to create the instance. For more information, see Create a VPC.

Precautions:
- You can create a maximum of 100 instances at a time.
- You can use the AutoReleaseTime parameter to set the time when to automatically release the instances.
- After instances are created, you can call the DescribeInstances operation to check their states.
- By default, instances automatically start after they are created. Instances are ready for use when they are in the Running (Running) state.
- As of November 27, 2020, the maximum bandwidth value available for you to create instances or change instance configurations is subject to the throttling policy of your account. To increase the maximum bandwidth value, submit a ticket. The throttling policy specifies the following requirements: Within a single region, the total maximum bandwidth value of all instances that use the pay-by-traffic billing method for network usage cannot exceed 5 Gbit/s and that of all instances that use the pay-by-bandwidth billing method for network usage cannot exceed 50 Gbit/s.
- Different from the CreateInstance operation, the RunInstances operation allows the system to assign public IP addresses to the new instances if you set the InternetMaxBandwidthOut parameter to a value greater than 0.
- After you call this operation, an error is returned if a parameter is invalid or if available resources are insufficient. For more information, see the "Error codes" section of this topic.

Note If the QuotaExceed.ElasticQuota error is returned when you create instances, you have reached the maximum number of instances of the specified instance type that can be created within the specified region or the maximum number of vCPUs for all instance types in a zone. You can go to the ECS console or Quota Center to request a quota increase.

Best practices:
- We recommend that you use auto provisioning groups in the following scenarios: Resources are insufficient to create more than 100 instances at a time, you want to create instances in a quick manner regardless of resource configurations such as instance types or zones, or you require a specific number of vCPUs regardless of the number of instances that need to be created. You can call the CreateAutoProvisioningGroup operation to create an auto provisioning group to deploy an instance cluster across different billing methods, instance families, and zones. For more information, see Use auto provisioning group-related API operations to create multiple ECS instances at the same time.
- You can call the RunInstances operation to batch create instances. To better manage and search for these instances, we recommend that you specify tags for the instances by using the Tag.N.Key and Tag.N.Value parameters. You can also append incremental suffixes (UniqueSuffix) to the hostname (HostName) and to the instance name (InstanceName).
- A launch template contains parameters required to create an instance so that you do not have to specify these parameters every time you create instances. You can call the CreateLaunchTemplate operation to create a launch template. Then, in your request to call the RunInstances operation, you can specify the LaunchTemplateId and LaunchTemplateVersion parameters to use the launch template.
- When you create an instance in the ECS console, you can view the best practices for calling the RunInstances operation. In the Preview step, click View Open API in the Configurations Selected section. In the dialog box that appears, the left-side API Workflow section shows the operations and request parameters that are related to the RunInstances operation. The right-side section shows SDK examples for the Java and Python programming languages.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

CpuOptions.Numa	String	No	1	The number of CPU Numa nodes.
SecurityOptions.TrustedSystemMode	String	No	vTPM	The trusted system mode. Set the value to vTPM. The trusted system mode supports the following instance families: g7, c7, and r7 Security-enhanced instance families: g7t, c7t, and r7t To create instances of the preceding instance families, you must set this parameter. Take note of the following items: To use the Alibaba Cloud trusted system, set this parameter to vTPM. Then, the Alibaba Cloud trusted system performs trust verifications when the instances start. If you do not want to use the Alibaba Cloud trusted system, leave this parameter empty. Note that if your created instances use an enclave-based confidential computing environment (with `SecurityOptions.ConfidentialComputingMode` set to Enclave), the Alibaba Cloud trusted system is enabled for the instances. When you use ECS API to create instances that use the trusted system, you can call only the `RunInstances` operation. The `CreateInstance` operation does not support the `SecurityOptions.TrustedSystemMode` parameter. For more information about the trusted system, see Overview. This parameter is empty by default.
SecurityOptions.ConfidentialComputingMode	String	No	Enclave	The confidential computing mode. Set the value to Enclave. A value of Enclave indicates that an enclave-based confidential computing environment is built on the instance. When you call the `RunInstances` operation, you can set this parameter only for c7, g7, or r7 instances to use enclave-based confidential computing. Take note of the following items: The confidential computing feature is in invitational preview. To use this feature, submit a ticket. When you use ECS API to create instances that support enclave-based confidential computing, you can call only the `RunInstances` operation. The `CreateInstance` operation does not support the `SecurityOptions.ConfidentialComputingMode` parameter. Enclave-based confidential computing is implemented based on the Alibaba Cloud trusted system (vTPM). When you build a confidential computing environment for an instance by using Enclave, the Alibaba Cloud trusted system is enabled for the instance. Therefore, if you set `SecurityOptions.ConfidentialComputingMode` to Enclave when you call this operation, the created instances use enclave-based confidential computing and the Alibaba Cloud trusted system regardless of whether you set `SecurityOptions.TrustedSystemMode` to vTPM. For more information about confidential computing, see Build a confidential computing environment by using enclave. This parameter is empty by default.
HttpEndpoint	String	No	enabled	Specifies whether to enable the access channel for instance metadata. Valid values: enabled: enables the access channel for instance metadata. disabled: disables the access channel for instance metadata. Default value: enabled. Note For more information about instance metadata, see Overview of ECS instance metadata.

Note For more information about modes of accessing instance metadata, see Access mode of instance metadata.
PrivatePoolOptions.MatchCriteria	String	No	Open	The type of the private pool. A private pool is generated after an elasticity assurance or capacity reservation takes effect. You can select the private pool when you create instances. Valid values: Open: open private pool. The system selects a matching open private pool to create the instance. If no matching open private pools are found, resources in the public pool are used. When you set this parameter to Open, you can leave the `PrivatePoolOptions.Id` parameter empty. Target: specified private pool. The capacity in a specified private pool is used. If the specified private pool is unavailable, the instance cannot be created. If you set this parameter to Target, you must specify the `PrivatePoolOptions.Id` parameter. None: no private pool. The capacity in private pools is not used. Default value: None. In the following scenarios, the PrivatePoolOptions.MatchCriteria parameter can be set only to `None` or left empty: A preemptible instance is to be created. The instance is to be created in the classic network. The instance is to be created on a dedicated host.
