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

Usage notes

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 see Best practices for instance type selection to learn about how to select instance types.
- Query for available resources: Call the DescribeAvailableResource operation to query resources available 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.

Comparison with CreateInstance:
RunInstances has the following advantages over CreateInstance:
- You can call the RunInstances operation to create up to 100 instances at a time, instead of repeatedly calling the CreateInstance operation.
- After an instance is created, the instance enters the Starting state and then transitions to the Running state. You do not need to call the StartInstance operation to start the instance.
- When you create an instance, you can specify InternetMaxBandwidthOut to assign a public IP address to the instance, without the need to call the AllocatePublicIpAddress operation.
- You can specify AutoReleaseTime to set the time when to automatically release the instances, without the need to call the ModifyInstanceAutoReleaseTime operation.
- You can specify LaunchTemplateId and LaunchTemplateVersion to use a launch template. This eliminates the need to configure a large number of parameters every time you create instances.
- You can specify UniqueSuffix to batch configure sequential names or hostnames for multiple instances for easy management and retrieval.
- When you call the RunInstances operation to create instances, you can configure the enclave-based confidential computing mode and the trusted system mode for the instances.
- You can set NetworkOptions.EnableJumboFrame to true to enable the Jumbo Frame feature when you create instances. For more information, see MTUs.
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 you create instances and obtain their IDs, you can call the DescribeInstances operation to check the status of the instances.
- By default, instances automatically start after they are created. Instances are ready for use when they are in the Running (Running) state.
- Starting from November 27, 2020, the maximum bandwidth value available for you to create ECS instances or to change ECS instance configurations is subject to the throttling policy of your account. To increase the maximum bandwidth value, submit a ticket. The throttling policy imposes the following constraints: 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 the total maximum bandwidth value 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 InternetMaxBandwidthOut to a value greater than 0.
- When you call the RunInstances operation to create an instance, you can use one of the following methods to attach a primary elastic network interface (ENI) to the instance. Note that you can use only one of the methods to configure the primary ENI in each call. Otherwise, the call fails and an error message is returned.
  - Specify parameters such as SecurityGroupId, VSwitchId, PrivateIpAddress, NetworkInterfaceQueueNumber, and Ipv6AddressCount to configure the primary ENI.
  - Specify parameters that start with NetworkInterface.N. to configure the primary and secondary ENIs. If NetworkInterface.N.InstanceType is set to Primary, the configured ENI is the primary ENI. If NetworkInterface.N.InstanceType is set to Secondary or left empty, the configured ENI is a secondary ENI.
- 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.
  - If 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 is exceeded, the QuotaExceed.ElasticQuota error is returned when you call this operation. You can go to the ECS console or Quota Center to request a quota increase.
  - If the capacity of disks that belong to the specified disk category exceeds the quota limit for the specified zone, the QuotaExceed.DiskCapacity error is returned when you call this operation. You can go to the Quota Center to view and increase the disk capacity quota.

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 quickly create instances regardless of resource configurations such as instance types or zones, or you want to create instances to consume a specific total number of vCPUs regardless of the number of instances. 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 add tags to the instances by specifying Tag.N.Key and Tag.N.Value. 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 LaunchTemplateId and LaunchTemplateVersion 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.

The hostname can contain letters, digits, and hyphens (-). For instances that run other operating systems such as Linux, take note of the following items: The hostname must be 2 to 64 characters in length. You can use periods (.) to separate a hostname into multiple segments. Each segment can contain letters, digits, and hyphens (-). You can use the `${instance_id}` placeholder to pass instance IDs into the hostname specified by `HostName`. For example, if you set `HostName` to k8s-${instance_id} and the instance is assigned an ID of `i-123abc**`, the hostname of the instance is `k8s-i-123abc**`. When you create multiple instances, you can perform the following operations: Batch configure sequential hostnames for the instances. For more information, see Batch configure sequential names or hostnames for multiple instances. Use `HostNames.N` to configure different hostnames for instances. You cannot specify both `HostName` and `HostNames.N`.

UserData	String	No	ZWNobyBoZWxsbyBlY3Mh	The user data of the instance. The user data must be encoded in Base64. The raw data can be up to 16 KB in size. Note If the instance type supports user data, you can use the UserData parameter to pass in user data. We recommend that you do not pass in confidential information (such as passwords or private keys) in plaintext as user data. This is because the system does not encrypt UserData values when API requests are transmitted. If you must pass in confidential information, we recommend that you encrypt and encode the information in Base64, and then decode and decrypt the information in the same way within the instance.
KeyPairName	String	No	KeyPair_Name	The name of the key pair to bind to the instance. Note For Windows instances, this parameter is ignored. This parameter is empty by default. The `Password` parameter takes effect even if the KeyPairName parameter is specified.
