# RunInstances Launches the specified number of instances using an AMI for which you have permissions. You can specify a number of options, or leave the default options. The following rules apply: + If you don't specify a subnet ID, we choose a default subnet from your default VPC for you. If you don't have a default VPC, you must specify a subnet ID in the request. + All instances have a network interface with a primary private IPv4 address. If you don't specify this address, we choose one from the IPv4 range of your subnet. + Not all instance types support IPv6 addresses. For more information, see [Instance types](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html). + If you don't specify a security group ID, we use the default security group for the VPC. For more information, see [Security groups](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html). + If any of the AMIs have a product code attached for which the user has not subscribed, the request fails. You can create a [launch template](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-launch-templates.html), which is a resource that contains the parameters to launch an instance. When you launch an instance using [RunInstances](#API_RunInstances), you can specify the launch template instead of specifying the launch parameters. To ensure faster instance launches, break up large requests into smaller batches. For example, create five separate launch requests for 100 instances each instead of one launch request for 500 instances. `RunInstances` is subject to both request rate limiting and resource rate limiting. For more information, see [Request throttling](https://docs.aws.amazon.com/ec2/latest/devguide/ec2-api-throttling.html). An instance is ready for you to use when it's in the `running` state. You can check the state of your instance using [DescribeInstances](API_DescribeInstances.md). You can tag instances and EBS volumes during launch, after launch, or both. For more information, see [CreateTags](API_CreateTags.md) and [Tagging your Amazon EC2 resources](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html). Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see [Key pairs](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html). For troubleshooting, see [What to do if an instance immediately terminates](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_InstanceStraightToTerminated.html), and [Troubleshooting connecting to your instance](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html). ## Request Parameters The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see [Common Query Parameters](CommonParameters.md). **AdditionalInfo** Reserved. Type: String Required: No **BlockDeviceMapping.N** The block device mapping, which defines the EBS volumes and instance store volumes to attach to the instance at launch. For more information, see [Block device mappings](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/block-device-mapping-concepts.html) in the *Amazon EC2 User Guide*. Type: Array of [BlockDeviceMapping](API_BlockDeviceMapping.md) objects Required: No **CapacityReservationSpecification** Information about the Capacity Reservation targeting option. If you do not specify this parameter, the instance's Capacity Reservation preference defaults to `open`, which enables it to run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone, and tenancy). Type: [CapacityReservationSpecification](API_CapacityReservationSpecification.md) object Required: No **ClientToken** Unique, case-sensitive identifier you provide to ensure the idempotency of the request. If you do not specify a client token, a randomly generated token is used for the request to ensure idempotency. For more information, see [Ensuring idempotency in Amazon EC2 API requests](https://docs.aws.amazon.com/ec2/latest/devguide/ec2-api-idempotency.html). Constraints: Maximum 64 ASCII characters Type: String Required: No **CpuOptions** The CPU options for the instance. For more information, see [Optimize CPU options](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-optimize-cpu.html) in the *Amazon EC2 User Guide*. Type: [CpuOptionsRequest](API_CpuOptionsRequest.md) object Required: No **CreditSpecification** The credit option for CPU usage of the burstable performance instance. Valid values are `standard` and `unlimited`. To change this attribute after launch, use [ ModifyInstanceCreditSpecification](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyInstanceCreditSpecification.html). For more information, see [Burstable performance instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances.html) in the *Amazon EC2 User Guide*. Default: `standard` (T2 instances) or `unlimited` (T3/T3a/T4g instances) For T3 instances with `host` tenancy, only `standard` is supported. Type: [CreditSpecificationRequest](API_CreditSpecificationRequest.md) object Required: No **DisableApiStop** Indicates whether an instance is enabled for stop protection. For more information, see [Enable stop protection for your EC2 instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-stop-protection.html). Type: Boolean Required: No **DisableApiTermination** Indicates whether termination protection is enabled for the instance. The default is `false`, which means that you can terminate the instance using the Amazon EC2 console, command line tools, or API. You can enable termination protection when you launch an instance, while the instance is running, or while the instance is stopped. Type: Boolean Required: No **DryRun** Checks whether you have the required permissions for the operation, without actually making the request, and provides an error response. If you have the required permissions, the error response is `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`. Type: Boolean Required: No **EbsOptimized** Indicates whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal Amazon EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS-optimized instance. Default: `false` Type: Boolean Required: No **ElasticGpuSpecification.N** *This parameter has been deprecated.* An elastic GPU to associate with the instance. Amazon Elastic Graphics reached end of life on January 8, 2024. Type: Array of [ElasticGpuSpecification](API_ElasticGpuSpecification.md) objects Required: No **ElasticInferenceAccelerator.N** *This parameter has been deprecated.* An elastic inference accelerator to associate with the instance. Amazon Elastic Inference is no longer available. Type: Array of [ElasticInferenceAccelerator](API_ElasticInferenceAccelerator.md) objects Required: No **EnablePrimaryIpv6** If you’re launching an instance into a dual-stack or IPv6-only subnet, you can enable assigning a primary IPv6 address. A primary IPv6 address is an IPv6 GUA address associated with an ENI that you have enabled to use a primary IPv6 address. Use this option if an instance relies on its IPv6 address not changing. When you launch the instance, AWS will automatically assign an IPv6 address associated with the ENI attached to your instance to be the primary IPv6 address. Once you enable an IPv6 GUA address to be a primary IPv6, you cannot disable it. When you enable an IPv6 GUA address to be a primary IPv6, the first IPv6 GUA will be made the primary IPv6 address until the instance is terminated or the network interface is detached. If you have multiple IPv6 addresses associated with an ENI attached to your instance and you enable a primary IPv6 address, the first IPv6 GUA address associated with the ENI becomes the primary IPv6 address. Type: Boolean Required: No **EnclaveOptions** Indicates whether the instance is enabled for AWS Nitro Enclaves. For more information, see [AWS Nitro Enclaves User Guide](https://docs.aws.amazon.com/enclaves/latest/user/). You can't enable AWS Nitro Enclaves and hibernation on the same instance. Type: [EnclaveOptionsRequest](API_EnclaveOptionsRequest.md) object Required: No **HibernationOptions** Indicates whether an instance is enabled for hibernation. This parameter is valid only if the instance meets the [hibernation prerequisites](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/hibernating-prerequisites.html). For more information, see [Hibernate your Amazon EC2 instance](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Hibernate.html) in the *Amazon EC2 User Guide*. You can't enable hibernation and AWS Nitro Enclaves on the same instance. Type: [HibernationOptionsRequest](API_HibernationOptionsRequest.md) object Required: No **IamInstanceProfile** The name or Amazon Resource Name (ARN) of an IAM instance profile. Type: [IamInstanceProfileSpecification](API_IamInstanceProfileSpecification.md) object Required: No **ImageId** The ID of the AMI. An AMI ID is required to launch an instance and must be specified here or in a launch template. Type: String Required: No **InstanceInitiatedShutdownBehavior** Indicates whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown). Default: `stop` Type: String Valid Values: `stop | terminate` Required: No **InstanceMarketOptions** The market (purchasing) option for the instances. Type: [InstanceMarketOptionsRequest](API_InstanceMarketOptionsRequest.md) object Required: No **InstanceType** The instance type. For more information, see [Amazon EC2 Instance Types Guide](https://docs.aws.amazon.com/ec2/latest/instancetypes/instance-types.html).
