ServiceManagedEBSVolumeConfiguration - Amazon Elastic Container Service
ContentsSee Also

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 in the Amazon Elastic Container Service Developer Guide.

Many of these parameters map 1:1 with the Amazon EBS CreateVolume API request parameters.

Contents

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 in the Amazon ECS Developer Guide.

Type: String

Required: Yes

encrypted

Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference.

Type: Boolean

Required: No

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 task 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.

Type: String

Valid Values: ext3 | ext4 | xfs | ntfs

Required: No

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 in the Amazon EC2 API Reference.

Type: Integer

Required: No

kmsKeyId

The Amazon Resource Name (ARN) identifier of the AWS Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no AWS Key Management Service key is specified, the default AWS managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference.

Important

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.

Type: String

Required: No

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 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

Type: Integer

Required: No

snapshotId

The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference.

Type: String

Required: No

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 in the Amazon EC2 API Reference.

Type: Array of EBSTagSpecification objects

Required: No

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 in the Amazon EC2 API Reference.

Important

This parameter is only supported for the gp3 volume type.

Type: Integer

Required: No

volumeType

The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference. For more information, see Amazon EBS volume types in the Amazon EC2 User Guide.

The following are the supported volume types.

  • General Purpose SSD: gp2|gp3

  • Provisioned IOPS SSD: io1|io2

  • Throughput Optimized HDD: st1

  • Cold HDD: sc1

  • Magnetic: standard

    Note

    The magnetic volume type is not supported on Fargate.

Type: String

Required: No
