AdditionalInfo
This property is reserved for internal use.
public string? AdditionalInfo { get; set; }Property Value
Remarks
If you use it, the stack fails with this error: Bad property set: [Testing this property] (Service: AmazonEC2; Status Code: 400; Error Code: InvalidParameterCombination; Request ID: 0XXXXXX-49c7-4b40-8bcc-76885dcXXXXX) .
Affinity
Indicates whether the instance is associated with a dedicated host.
public string? Affinity { get; set; }Property Value
Remarks
If you want the instance to always restart on the same host on which it was launched, specify host . If you want the instance to restart on any available host, but try to launch onto the last host it ran on (on a best-effort basis), specify default .
AvailabilityZone
The Availability Zone of the instance.
public string? AvailabilityZone { get; set; }Property Value
Remarks
If not specified, an Availability Zone will be automatically chosen for you based on the load balancing criteria for the Region.
This parameter is not supported by DescribeImageAttribute .
BlockDeviceMappings
The block device mapping entries that defines the block devices to attach to the instance at launch.
public object? BlockDeviceMappings { get; set; }Property Value
Remarks
By default, the block devices specified in the block device mapping for the AMI are used. You can override the AMI block device mapping using the instance block device mapping. For the root volume, you can override only the volume size, volume type, volume encryption settings, and the DeleteOnTermination setting.
After the instance is running, you can modify only the <code>DeleteOnTermination</code> parameter for the attached volumes without interrupting the instance. Modifying any other parameter results in instance <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement">replacement</a> .
CpuOptions
The CPU options for the instance.
public object? CpuOptions { get; set; }Property Value
Remarks
For more information, see Optimize CPU options in the Amazon Elastic Compute Cloud User Guide .
CreditSpecification
The credit option for CPU usage of the burstable performance instance.
public object? CreditSpecification { get; set; }Property Value
Remarks
Valid values are standard and unlimited . To change this attribute after launch, use ModifyInstanceCreditSpecification . For more information, see Burstable performance instances 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.
DisableApiTermination
Indicates whether termination protection is enabled for the instance.
public object? DisableApiTermination { get; set; }Property Value
Remarks
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.
EbsOptimized
Indicates whether the instance is optimized for Amazon EBS I/O.
public object? EbsOptimized { get; set; }Property Value
Remarks
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
ElasticGpuSpecifications
An elastic GPU to associate with the instance.
public object? ElasticGpuSpecifications { get; set; }Property Value

HostId
If you specify host for the Affinity property, the ID of a dedicated host that the instance is associated with.
public string? HostId { get; set; }Property Value
Remarks
If you don't specify an ID, Amazon EC2 launches the instance onto any available, compatible dedicated host in your account. This type of launch is called an untargeted launch. Note that for untargeted launches, you must have a compatible, dedicated host available to successfully launch instances.
HostResourceGroupArn
The ARN of the host resource group in which to launch the instances.
public string? HostResourceGroupArn { get; set; }Property Value
Remarks
If you specify a host resource group ARN, omit the Tenancy parameter or set it to host .
IamInstanceProfile
The name of an IAM instance profile.
public string? IamInstanceProfile { get; set; }Property Value
Remarks
To create a new IAM instance profile, use the AWS::IAM::InstanceProfile resource.
ImageId
The ID of the AMI.
public string? ImageId { get; set; }Property Value
Remarks
An AMI ID is required to launch an instance and must be specified here or in a launch template.
InstanceInitiatedShutdownBehavior
Indicates whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown).

Remarks
InstanceType
The instance type. For more information, see Instance types in the Amazon EC2 User Guide .
public string? InstanceType { get; set; }Property Value
Remarks
When you change your EBS-backed instance type, instance restart or replacement behavior depends on the instance type compatibility between the old and new types. An instance with an instance store volume as the root volume is always replaced. For more information, see Change the instance type in the Amazon EC2 User Guide .
Ipv6AddressCount
The number of IPv6 addresses to associate with the primary network interface.
public double? Ipv6AddressCount { get; set; }Property Value
Remarks
Amazon EC2 chooses the IPv6 addresses from the range of your subnet. You cannot specify this option and the option to assign specific IPv6 addresses in the same request. You can specify this option if you've specified a minimum number of instances to launch.
You cannot specify this option and the network interfaces option in the same request.
Ipv6Addresses
The IPv6 addresses from the range of the subnet to associate with the primary network interface.
public object? Ipv6Addresses { get; set; }Property Value
Remarks
You cannot specify this option and the option to assign a number of IPv6 addresses in the same request. You cannot specify this option if you've specified a minimum number of instances to launch.
You cannot specify this option and the network interfaces option in the same request.
KernelId
The ID of the kernel.
public string? KernelId { get; set; }Property Value
Remarks
We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UserProvidedkernels.html">PV-GRUB</a> in the <em>Amazon EC2 User Guide</em> .
KeyName
The name of the key pair. You can create a key pair using CreateKeyPair or ImportKeyPair .
public string? KeyName { get; set; }Property Value
Remarks
If you do not specify a key pair, you can't connect to the instance unless you choose an AMI that is configured to allow users another way to log in.
LaunchTemplate
The launch template.
public object? LaunchTemplate { get; set; }Property Value
Remarks
Any additional parameters that you specify for the new instance overwrite the corresponding parameters included in the launch template.
LicenseSpecifications
The license configurations.
public object? LicenseSpecifications { get; set; }Property Value
Remarks
MetadataOptions
The metadata options for the instance.
public object? MetadataOptions { get; set; }Property Value
Remarks
Monitoring
Specifies whether detailed monitoring is enabled for the instance.
public object? Monitoring { get; set; }Property Value
Remarks
Specify true to enable detailed monitoring. Otherwise, basic monitoring is enabled. For more information about detailed monitoring, see Enable or turn off detailed monitoring for your instances in the Amazon EC2 User Guide .
NetworkInterfaces
The network interfaces to associate with the instance.
public object? NetworkInterfaces { get; set; }Property Value
Remarks
If you use this property to point to a network interface, you must terminate the original interface before attaching a new one to allow the update of the instance to succeed.
If this resource has a public IP address and is also in a VPC that is defined in the same template, you must use the DependsOn Attribute to declare a dependency on the VPC-gateway attachment.
PlacementGroupName
The name of an existing placement group that you want to launch the instance into (cluster | partition | spread).
public string? PlacementGroupName { get; set; }Property Value
Remarks
PrivateDnsNameOptions
The options for the instance hostname.
public object? PrivateDnsNameOptions { get; set; }Property Value
Remarks
PrivateIpAddress
The primary IPv4 address. You must specify a value from the IPv4 address range of the subnet.
public string? PrivateIpAddress { get; set; }Property Value
Remarks
Only one private IP address can be designated as primary. You can't specify this option if you've specified the option to designate a private IP address as the primary IP address in a network interface specification. You cannot specify this option if you're launching more than one instance in the request.
You cannot specify this option and the network interfaces option in the same request.
If you make an update to an instance that requires replacement, you must assign a new private IP address. During a replacement, AWS CloudFormation creates a new instance but doesn't delete the old instance until the stack has successfully updated. If the stack update fails, AWS CloudFormation uses the old instance to roll back the stack to the previous working state. The old and new instances cannot have the same private IP address.
PropagateTagsToVolumeOnCreation
Indicates whether to assign the tags specified in the Tags property to the volumes specified in the BlockDeviceMappings property.
public object? PropagateTagsToVolumeOnCreation { get; set; }Property Value
Remarks
Note that using this feature does not assign the tags to volumes that are created separately and then attached using AWS::EC2::VolumeAttachment .
RamdiskId
The ID of the RAM disk to select.
public string? RamdiskId { get; set; }Property Value
Remarks
Some kernels require additional drivers at launch. Check the kernel requirements for information about whether you need to specify a RAM disk. To find kernel requirements, go to the AWS Resource Center and search for the kernel ID.
We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UserProvidedkernels.html">PV-GRUB</a> in the <em>Amazon EC2 User Guide</em> .
SecurityGroupIds
The IDs of the security groups.
public string[]? SecurityGroupIds { get; set; }Property Value
string[]
Remarks
You can specify the IDs of existing security groups and references to resources created by the stack template.
If you specify a network interface, you must specify any security groups as part of the network interface.
SecurityGroups
[Default VPC] The names of the security groups. For a nondefault VPC, you must use security group IDs instead.
public string[]? SecurityGroups { get; set; }Property Value
string[]
Remarks
You cannot specify this option and the network interfaces option in the same request. The list can contain both the name of existing Amazon EC2 security groups or references to AWS::EC2::SecurityGroup resources created in the template.
Default: Amazon EC2 uses the default security group.
SourceDestCheck
Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives.
public object? SourceDestCheck { get; set; }Property Value
Remarks
If the value is true , source/destination checks are enabled; otherwise, they are disabled. The default value is true . You must disable source/destination checks if the instance runs services such as network address translation, routing, or firewalls.
SsmAssociations
The SSM document and parameter values in AWS Systems Manager to associate with this instance. To use this property, you must specify an IAM instance profile role for the instance. For more information, see Create an IAM instance profile for Systems Manager in the AWS Systems Manager User Guide .
public object? SsmAssociations { get; set; }Property Value
Remarks
You can associate only one document with an instance.
SubnetId
The ID of the subnet to launch the instance into.
public string? SubnetId { get; set; }Property Value
Remarks
If you specify a network interface, you must specify any subnets as part of the network interface instead of using this parameter.
Tags
The tags to add to the instance.
public ICfnTag[]? Tags { get; set; }Property Value
ICfnTag[]
Remarks
These tags are not applied to the EBS volumes, such as the root volume, unless PropagateTagsToVolumeOnCreation is true .
Tenancy
The tenancy of the instance.
public string? Tenancy { get; set; }Property Value
Remarks
An instance with a tenancy of dedicated runs on single-tenant hardware.
UserData
The parameters or scripts to store as user data.
public string? UserData { get; set; }Property Value
Remarks
Any scripts in user data are run when you launch the instance. User data is limited to 16 KB. You must provide base64-encoded text. For more information, see Fn::Base64 .
If the root volume is an EBS volume and you update user data, CloudFormation restarts the instance. If the root volume is an instance store volume and you update user data, the instance is replaced.
Volumes
The volumes to attach to the instance.
public object? Volumes { get; set; }
