//
// Example:
//   // The code below shows an example of how to instantiate this type.

type CfnLaunchTemplate_EbsProperty struct {
	// Indicates whether the EBS volume is deleted on instance termination.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-deleteontermination
	//
	DeleteOnTermination interface{} `field:"optional" json:"deleteOnTermination" yaml:"deleteOnTermination"`
	// Indicates whether the EBS volume is encrypted.
	//
	// Encrypted volumes can only be attached to instances that support Amazon EBS encryption. If you are creating a volume from a snapshot, you can't specify an encryption value.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-encrypted
	//
	Encrypted interface{} `field:"optional" json:"encrypted" yaml:"encrypted"`
	// The number of I/O operations per second (IOPS).
	//
	// For `gp3` , `io1` , and `io2` volumes, this represents the number of IOPS that are provisioned for the volume. For `gp2` volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
	//
	// The following are the supported values for each volume type:
	//
	// - `gp3` : 3,000 - 16,000 IOPS
	// - `io1` : 100 - 64,000 IOPS
	// - `io2` : 100 - 256,000 IOPS
	//
	// For `io2` volumes, you can achieve up to 256,000 IOPS on [instances built on the Nitro System](https://docs.aws.amazon.com/ec2/latest/instancetypes/ec2-nitro-instances.html) . On other instances, you can achieve performance up to 32,000 IOPS.
	//
	// This parameter is supported for `io1` , `io2` , and `gp3` volumes only.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-iops
	//
	Iops *float64 `field:"optional" json:"iops" yaml:"iops"`
	// Identifier (key ID, key alias, key ARN, or alias ARN) of the customer managed KMS key to use for EBS encryption.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-kmskeyid
	//
	KmsKeyId *string `field:"optional" json:"kmsKeyId" yaml:"kmsKeyId"`
	// The ID of the snapshot.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-snapshotid
	//
	SnapshotId *string `field:"optional" json:"snapshotId" yaml:"snapshotId"`
	// The throughput to provision for a `gp3` volume, with a maximum of 1,000 MiB/s.
	//
	// Valid Range: Minimum value of 125. Maximum value of 1000.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-throughput
	//
	Throughput *float64 `field:"optional" json:"throughput" yaml:"throughput"`
	// Specifies the Amazon EBS Provisioned Rate for Volume Initialization (volume initialization rate), in MiB/s, at which to download the snapshot blocks from Amazon S3 to the volume.
	//
	// This is also known as *volume initialization* . Specifying a volume initialization rate ensures that the volume is initialized at a predictable and consistent rate after creation.
	//
	// This parameter is supported only for volumes created from snapshots. Omit this parameter if:
	//
	// - You want to create the volume using fast snapshot restore. You must specify a snapshot that is enabled for fast snapshot restore. In this case, the volume is fully initialized at creation.
	//
	// > If you specify a snapshot that is enabled for fast snapshot restore and a volume initialization rate, the volume will be initialized at the specified rate instead of fast snapshot restore.
	// - You want to create a volume that is initialized at the default rate.
	//
	// For more information, see [Initialize Amazon EBS volumes](https://docs.aws.amazon.com/ebs/latest/userguide/initalize-volume.html) in the *Amazon EC2 User Guide* .
	//
	// Valid range: 100 - 300 MiB/s.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-volumeinitializationrate
	//
	VolumeInitializationRate *float64 `field:"optional" json:"volumeInitializationRate" yaml:"volumeInitializationRate"`
	// The size of the volume, in GiBs.
	//
	// You must specify either a snapshot ID or a volume size. The following are the supported volumes sizes for each volume type:
	//
	// - `gp2` and `gp3` : 1 - 16,384 GiB
	// - `io1` : 4 - 16,384 GiB
	// - `io2` : 4 - 65,536 GiB
	// - `st1` and `sc1` : 125 - 16,384 GiB
	// - `standard` : 1 - 1024 GiB.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-launchtemplate-ebs.html#cfn-ec2-launchtemplate-ebs-volumesize
	//
	VolumeSize *float64 `field:"optional" json:"volumeSize" yaml:"volumeSize"`
	// The volume type.
	//
	// For more information, see [Amazon EBS volume types](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-volume-types.html) in the *Amazon EBS User Guide* .
