Overview
When passing Ebs as input to an Aws::Client method, you can use a vanilla Hash:
{
snapshot_id: "XmlStringMaxLen255",
volume_size: 1,
volume_type: "BlockDeviceEbsVolumeType",
delete_on_termination: false,
iops: 1,
encrypted: false,
}
Describes information used to set up an Amazon EBS volume specified in a block device mapping.
Returned by:
Instance Attribute Summary collapse
-
#delete_on_termination ⇒ Boolean
Indicates whether the volume is deleted on instance termination.
-
#encrypted ⇒ Boolean
Specifies whether the volume should be encrypted.
-
#iops ⇒ Integer
The number of I/O operations per second (IOPS) to provision for the volume.
-
#snapshot_id ⇒ String
The snapshot ID of the volume to use.
-
#volume_size ⇒ Integer
The volume size, in Gibibytes (GiB).
-
#volume_type ⇒ String
The volume type, which can be
standard
for Magnetic,io1
for Provisioned IOPS SSD,gp2
for General Purpose SSD,st1
for Throughput Optimized HDD, orsc1
for Cold HDD.
Instance Attribute Details
#delete_on_termination ⇒ Boolean
Indicates whether the volume is deleted on instance termination. For
Amazon EC2 Auto Scaling, the default value is true
.
#encrypted ⇒ Boolean
Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported Instance Types. If your AMI uses encrypted volumes, you can also only launch it on supported instance types.
Enabling encryption by default results in all EBS volumes being encrypted with the AWS managed CMK or a customer managed CMK, whether or not the snapshot was encrypted.
For more information, see Using Encryption with EBS-Backed AMIs in the Amazon EC2 User Guide for Linux Instances and Required CMK key policy for use with encrypted volumes in the Amazon EC2 Auto Scaling User Guide.
#iops ⇒ Integer
The number of I/O operations per second (IOPS) to provision for the volume. The maximum ratio of IOPS to volume size (in GiB) is 50:1. For more information, see Amazon EBS Volume Types in the Amazon EC2 User Guide for Linux Instances.
Required when the volume type is io1
. (Not used with standard
,
gp2
, st1
, or sc1
volumes.)
#snapshot_id ⇒ String
The snapshot ID of the volume to use.
You must specify either a VolumeSize
or a SnapshotId
.
#volume_size ⇒ Integer
The volume size, in Gibibytes (GiB).
This can be a number from 1-1,024 for standard
, 4-16,384 for io1
,
1-16,384 for gp2
, and 500-16,384 for st1
and sc1
. If you specify a
snapshot, the volume size must be equal to or larger than the snapshot
size.
Default: If you create a volume from a snapshot and you don\'t specify a volume size, the default is the snapshot size.
You must specify either a VolumeSize
or a SnapshotId
. If you specify
both SnapshotId
and VolumeSize
, the volume size must be equal or
greater than the size of the snapshot.
#volume_type ⇒ String
The volume type, which can be standard
for Magnetic, io1
for
Provisioned IOPS SSD, gp2
for General Purpose SSD, st1
for
Throughput Optimized HDD, or sc1
for Cold HDD. For more information,
see Amazon EBS Volume Types in the Amazon EC2 User Guide for Linux
Instances.
