This is the new *CloudFormation Template Reference Guide*. Please update your bookmarks and links. For help getting started with CloudFormation, see the [AWS CloudFormation User Guide](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/Welcome.html). # AWS::ECS::Service ServiceManagedEBSVolumeConfiguration The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. For information about the supported launch types and operating systems, see [Supported operating systems and launch types](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ebs-volumes.html#ebs-volumes-configuration) in the* Amazon Elastic Container Service Developer Guide*. Many of these parameters map 1:1 with the Amazon EBS `CreateVolume` API request parameters. ## Syntax To declare this entity in your CloudFormation template, use the following syntax: ### JSON ``` { "[Encrypted](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-encrypted)" : {{Boolean}}, "[FilesystemType](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-filesystemtype)" : {{String}}, "[Iops](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-iops)" : {{Integer}}, "[KmsKeyId](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-kmskeyid)" : {{String}}, "[RoleArn](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-rolearn)" : {{String}}, "[SizeInGiB](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-sizeingib)" : {{Integer}}, "[SnapshotId](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-snapshotid)" : {{String}}, "[TagSpecifications](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-tagspecifications)" : {{[ EBSTagSpecification, ... ]}}, "[Throughput](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-throughput)" : {{Integer}}, "[VolumeInitializationRate](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-volumeinitializationrate)" : {{Integer}}, "[VolumeType](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-volumetype)" : {{String}} } ``` ### YAML ``` [Encrypted](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-encrypted): {{Boolean}} [FilesystemType](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-filesystemtype): {{String}} [Iops](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-iops): {{Integer}} [KmsKeyId](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-kmskeyid): {{String}} [RoleArn](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-rolearn): {{String}} [SizeInGiB](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-sizeingib): {{Integer}} [SnapshotId](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-snapshotid): {{String}} [TagSpecifications](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-tagspecifications): {{ - EBSTagSpecification}} [Throughput](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-throughput): {{Integer}} [VolumeInitializationRate](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-volumeinitializationrate): {{Integer}} [VolumeType](#cfn-ecs-service-servicemanagedebsvolumeconfiguration-volumetype): {{String}} ``` ## Properties `Encrypted` Indicates whether the volume should be encrypted. If you turn on Region-level Amazon EBS encryption by default but set this value as `false`, the setting is overridden and the volume is encrypted with the KMS key specified for Amazon EBS encryption by default. This parameter maps 1:1 with the `Encrypted` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. *Required*: No *Type*: Boolean *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `FilesystemType` The filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the tasks will fail to start. The available Linux filesystem types are `ext3`, `ext4`, and `xfs`. If no value is specified, the `xfs` filesystem type is used by default. The available Windows filesystem types are `NTFS`. *Required*: No *Type*: String *Allowed values*: `ext3 | ext4 | xfs | ntfs` *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `Iops` 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 This parameter is required for `io1` and `io2` volume types. The default for `gp3` volumes is `3,000 IOPS`. This parameter is not supported for `st1`, `sc1`, or `standard` volume types. This parameter maps 1:1 with the `Iops` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. *Required*: No *Type*: Integer *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `KmsKeyId` The Amazon Resource Name (ARN) identifier of the AWS Key Management Service key to use for Amazon EBS encryption. When a key is specified using this parameter, it overrides Amazon EBS default encryption or any KMS key that you specified for cluster-level managed storage encryption. This parameter maps 1:1 with the `KmsKeyId` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. For more information about encrypting Amazon EBS volumes attached to tasks, see [Encrypt data stored in Amazon EBS volumes attached to Amazon ECS tasks](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ebs-kms-encryption.html). AWS authenticates the AWS Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails. *Required*: No *Type*: String *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `RoleArn` The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your AWS infrastructure. We recommend using the Amazon ECS-managed `AmazonECSInfrastructureRolePolicyForVolumes` IAM policy with this role. For more information, see [Amazon ECS infrastructure IAM role](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/infrastructure_IAM_role.html) in the *Amazon ECS Developer Guide*. *Required*: Yes *Type*: String *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `SizeInGiB` The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the `Size` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. The following are the supported volume size values for each volume type. + `gp2` and `gp3`: 1-16,384 + `io1` and `io2`: 4-16,384 + `st1` and `sc1`: 125-16,384 + `standard`: 1-1,024 *Required*: No *Type*: Integer *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `SnapshotId` The snapshot that Amazon ECS uses to create volumes for attachment to tasks maintained by the service. You must specify either `snapshotId` or `sizeInGiB` in your volume configuration. This parameter maps 1:1 with the `SnapshotId` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. *Required*: No *Type*: String *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `TagSpecifications` The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the `TagSpecifications.N` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. *Required*: No *Type*: Array of [EBSTagSpecification](aws-properties-ecs-service-ebstagspecification.md) *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `Throughput` The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the `Throughput` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. This parameter is only supported for the `gp3` volume type. *Required*: No *Type*: Integer *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `VolumeInitializationRate` The rate, in MiB/s, at which data is fetched from a snapshot of an existing EBS volume to create new volumes for attachment to the tasks maintained by the service. This property can be specified only if you specify a `snapshotId`. For more information, see [Initialize Amazon EBS volumes](https://docs.aws.amazon.com/ebs/latest/userguide/initalize-volume.html) in the *Amazon EBS User Guide*. *Required*: No *Type*: Integer *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `VolumeType` The volume type. This parameter maps 1:1 with the `VolumeType` parameter of the [CreateVolume API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateVolume.html) in the *Amazon EC2 API Reference*. For more information, see [Amazon EBS volume types](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html) in the *Amazon EC2 User Guide*.
