Example:

# instance: ec2.Instance
# role: iam.Role


volume = ec2.Volume(self, "Volume",
    availability_zone="us-west-2a",
    size=Size.gibibytes(500),
    encrypted=True
)

volume.grant_attach_volume(role, [instance])
Parameters:

  • scope (Construct) –

  • id (str) –

  • availability_zone (str) – The Availability Zone in which to create the volume.

  • auto_enable_io (Optional[bool]) – Indicates whether the volume is auto-enabled for I/O operations. By default, Amazon EBS disables I/O to the volume from attached EC2 instances when it determines that a volume’s data is potentially inconsistent. If the consistency of the volume is not a concern, and you prefer that the volume be made available immediately if it’s impaired, you can configure the volume to automatically enable I/O. Default: false

  • enable_multi_attach (Optional[bool]) – Indicates whether Amazon EBS Multi-Attach is enabled. See {@link https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volumes-multi.html#considerations|Considerations and limitations} for the constraints of multi-attach. Default: false

  • encrypted (Optional[bool]) – Specifies whether the volume should be encrypted. The effect of setting the encryption state to true depends on the volume origin (new or from a snapshot), starting encryption state, ownership, and whether encryption by default is enabled. For more information, see {@link https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#encryption-by-default|Encryption by Default} in the Amazon Elastic Compute Cloud User Guide. Encrypted Amazon EBS volumes must be attached to instances that support Amazon EBS encryption. For more information, see {@link https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#EBSEncryption_supported_instances|Supported Instance Types.} Default: false

  • encryption_key (Optional[IKey]) – The customer-managed encryption key that is used to encrypt the Volume. The encrypted property must be true if this is provided. Note: If using an {@link aws-kms.IKey} created from a {@link aws-kms.Key.fromKeyArn()} here, then the KMS key must have the following in its Key policy; otherwise, the Volume will fail to create:: { “Effect”: “Allow”, “Principal”: { “AWS”: “<arn for your account-user> ex: arn:aws:iam::00000000000:root” }, “Resource”: “*”, “Action”: [ “kms:DescribeKey”, “kms:GenerateDataKeyWithoutPlainText”, ], “Condition”: { “StringEquals”: { “kms:ViaService”: “ec2.<Region>.amazonaws.com”, (eg: ec2.us-east-1.amazonaws.com) “kms:CallerAccount”: “0000000000” (your account ID) } } } Default: The default KMS key for the account, region, and EC2 service is used.

  • iops (Union[int, float, None]) – The number of I/O operations per second (IOPS) to provision for the volume. The maximum ratio is 50 IOPS/GiB for PROVISIONED_IOPS_SSD, and 500 IOPS/GiB for both PROVISIONED_IOPS_SSD_IO2 and GENERAL_PURPOSE_SSD_GP3. See {@link https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-ebs-volume.html} for more information. This parameter is valid only for PROVISIONED_IOPS_SSD, PROVISIONED_IOPS_SSD_IO2 and GENERAL_PURPOSE_SSD_GP3 volumes. Default: None – Required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS if omitted.

  • removal_policy (Optional[RemovalPolicy]) – Policy to apply when the volume is removed from the stack. Default: RemovalPolicy.RETAIN

  • size (Optional[Size]) – The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. See {@link https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-ebs-volume.html} for details on the allowable size for each type of volume. Default: If you’re creating the volume from a snapshot and don’t specify a volume size, the default is the snapshot size.

  • snapshot_id (Optional[str]) – The snapshot from which to create the volume. You must specify either a snapshot ID or a volume size. Default: The EBS volume is not created from a snapshot.

  • volume_name (Optional[str]) – The value of the physicalName property of this resource. Default: The physical name will be allocated by CloudFormation at deployment time

  • volume_type (Optional[EbsDeviceVolumeType]) – The type of the volume; what type of storage to use to form the EBS Volume. Default: {@link EbsDeviceVolumeType.GENERAL_PURPOSE_SSD}

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (RemovalPolicy) –

Return type:

None

grant_attach_volume(grantee, instances=None)

Grants permission to attach this Volume to an instance.

CAUTION: Granting an instance permission to attach to itself using this method will lead to an unresolvable circular reference between the instance role and the instance. Use {@link IVolume.grantAttachVolumeToSelf} to grant an instance permission to attach this volume to itself.

Parameters:
Return type:

Grant

grant_attach_volume_by_resource_tag(grantee, constructs, tag_key_suffix=None)

Grants permission to attach the Volume by a ResourceTag condition.

If you are looking to grant an Instance, AutoScalingGroup, EC2-Fleet, SpotFleet, ECS host, etc the ability to attach this volume to itself then this is the method you want to use.

This is implemented by adding a Tag with key VolumeGrantAttach-<suffix> to the given constructs and this Volume, and then conditioning the Grant such that the grantee is only given the ability to AttachVolume if both the Volume and the destination Instance have that tag applied to them.

Parameters:

  • grantee (IGrantable) –

  • constructs (Sequence[Construct]) –

  • tag_key_suffix (Optional[str]) –

Return type:

Grant

grant_detach_volume(grantee, instances=None)

Grants permission to detach this Volume from an instance CAUTION: Granting an instance permission to detach from itself using this method will lead to an unresolvable circular reference between the instance role and the instance.

Use {@link IVolume.grantDetachVolumeFromSelf} to grant an instance permission to detach this volume from itself.

Parameters:
Return type:

Grant

grant_detach_volume_by_resource_tag(grantee, constructs, tag_key_suffix=None)

Grants permission to detach the Volume by a ResourceTag condition.

This is implemented via the same mechanism as {@link IVolume.grantAttachVolumeByResourceTag}, and is subject to the same conditions.

Parameters:

  • grantee (IGrantable) –

  • constructs (Sequence[Construct]) –

  • tag_key_suffix (Optional[str]) –

Return type:

Grant

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

us-west-2a).

Type:

The availability zone that the EBS Volume is contained within (ex

encryption_key

The customer-managed encryption key that is used to encrypt the Volume.

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

node

The construct tree node associated with this construct.

stack

The stack in which this resource is defined.

volume_id

The EBS Volume’s ID.

Static Methods

classmethod from_volume_attributes(scope, id, *, availability_zone, volume_id, encryption_key=None)

Import an existing EBS Volume into the Stack.

Parameters:

  • scope (Construct) – the scope of the import.

  • id (str) – the ID of the imported Volume in the construct tree.

  • availability_zone (str) – The availability zone that the EBS Volume is contained within (ex: us-west-2a).

  • volume_id (str) – The EBS Volume’s ID.

  • encryption_key (Optional[IKey]) – The customer-managed encryption key that is used to encrypt the Volume. Default: None – The EBS Volume is not using a customer-managed KMS key for encryption.

Return type:

IVolume

classmethod is_construct(x)
