Overview

Note:

When passing EbsBlockDevice as input to an Aws::Client method, you can use a vanilla Hash:

{
  encrypted: false,
  delete_on_termination: false,
  iops: 1,
  kms_key_id: "String",
  snapshot_id: "String",
  volume_size: 1,
  volume_type: "standard", # accepts standard, io1, gp2, sc1, st1
}

Describes a block device for an EBS volume.

Instance Attribute Details

#delete_on_terminationBoolean

Indicates whether the EBS volume is deleted on instance termination.

Returns:

  • (Boolean)

    Indicates whether the EBS volume is deleted on instance termination.

#encryptedBoolean

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. This is because only blank volumes can be encrypted on creation.

Returns:

  • (Boolean)

    Indicates whether the EBS volume is encrypted.

#iopsInteger

The number of I/O operations per second (IOPS) that the volume supports. For io1, this represents the number of IOPS that are provisioned for the volume. For gp2, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information about General Purpose SSD baseline performance, I/O credits, and bursting, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide.

Constraint: Range is 100-20000 IOPS for io1 volumes and 100-10000 IOPS for gp2 volumes.

Condition: This parameter is required for requests to create io1 volumes; it is not used in requests to create gp2, st1, sc1, or standard volumes.

Returns:

  • (Integer)

    The number of I/O operations per second (IOPS) that the volume supports.

#kms_key_idString

ID for a user-managed CMK under which the EBS volume is encrypted.

Note: This parameter is only supported on BlockDeviceMapping objects called by RunInstances, RequestSpotFleet, and RequestSpotInstances.

Returns:

  • (String)

    ID for a user-managed CMK under which the EBS volume is encrypted.

#snapshot_idString

The ID of the snapshot.

Returns:

  • (String)

    The ID of the snapshot.

#volume_sizeInteger

The size of the volume, in GiB.

Constraints: 1-16384 for General Purpose SSD (gp2), 4-16384 for Provisioned IOPS SSD (io1), 500-16384 for Throughput Optimized HDD (st1), 500-16384 for Cold HDD (sc1), and 1-1024 for Magnetic (standard) volumes. If you specify a snapshot, the volume size must be equal to or larger than the snapshot size.

Default: If you\'re creating the volume from a snapshot and don\'t specify a volume size, the default is the snapshot size.

Returns:

  • (Integer)

    The size of the volume, in GiB.

#volume_typeString

The volume type: gp2, io1, st1, sc1, or standard.

Default: standard

Possible values:

  • standard
  • io1
  • gp2
  • sc1
  • st1

Returns:

  • (String)

    The volume type: gp2, io1, st1, sc1, or standard.
