Note that for untargeted launches, you must have a compatible, dedicated host available to successfully launch instances.

  • host_resource_group_arn (Optional[str]) – The ARN of the host resource group in which to launch the instances. If you specify a host resource group ARN, omit the Tenancy parameter or set it to host .

  • iam_instance_profile (Optional[str]) – The name of an IAM instance profile. To create a new IAM instance profile, use the AWS::IAM::InstanceProfile resource.

  • image_id (Optional[str]) – The ID of the AMI. An AMI ID is required to launch an instance and must be specified here or in a launch template.

  • instance_initiated_shutdown_behavior (Optional[str]) – Indicates whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown). Default: stop

  • network_interfaces (Union[IResolvable, Sequence[Union[IResolvable, NetworkInterfaceProperty, Dict[str, Any]]], None]) – The network interfaces to associate with the instance. .. epigraph:: 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.

  • placement_group_name (Optional[str]) – The name of an existing placement group that you want to launch the instance into (cluster | partition | spread).

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.

  • propagate_tags_to_volume_on_creation (Union[bool, IResolvable, None]) – Indicates whether to assign the tags from the instance to all of the volumes attached to the instance at launch.

    The ID of the RAM disk to select. 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. .. epigraph:: We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see PV-GRUB in the Amazon EC2 User Guide .

  • security_group_ids (Optional[Sequence[str]]) – The IDs of the security groups. You can create a security group using CreateSecurityGroup . If you specify a network interface, you must specify any security groups as part of the network interface.

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.

  • source_dest_check (Union[bool, IResolvable, None]) – Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives. If the value is true , source/destination checks are enabled; otherwise, they are disabled. The default value is true .

network_interfaces

The network interfaces to associate with the instance.

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.

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-networkinterfaces

placement_group_name

The name of an existing placement group that you want to launch the instance into (cluster | partition | spread).

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-placementgroupname

private_dns_name_options

The options for the instance hostname.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-privatednsnameoptions

private_ip_address

[EC2-VPC] The primary IPv4 address. You must specify a value from the IPv4 address range of the subnet.

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.

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-privateipaddress

propagate_tags_to_volume_on_creation

Indicates whether to assign the tags from the instance to all of the volumes attached to the instance at launch.

If you specify true and you assign tags to the instance, those tags are automatically assigned to all of the volumes that you attach to the instance at launch. If you specify false , those tags are not assigned to the attached volumes.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-propagatetagstovolumeoncreation

ramdisk_id

The ID of the RAM disk to select.

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. .. epigraph:

We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see `PV-GRUB <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UserProvidedkernels.html>`_ in the *Amazon EC2 User Guide* .

security_group_ids

//docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateSecurityGroup.html>`_ .

If you specify a network interface, you must specify any security groups as part of the network interface.

Link:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-securitygroupids

Type:

The IDs of the security groups. You can create a security group using `CreateSecurityGroup <https

security_groups

[EC2-Classic, default VPC] The names of the security groups.

For a nondefault VPC, you must use security group IDs instead.

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.

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html#cfn-ec2-instance-securitygroups

source_dest_check

Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives.

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.
