CfnVolume

class aws_cdk.aws_ec2.CfnVolume(scope, id, *, availability_zone, auto_enable_io=None, encrypted=None, iops=None, kms_key_id=None, multi_attach_enabled=None, outpost_arn=None, size=None, snapshot_id=None, tags=None, throughput=None, volume_type=None)

Bases: aws_cdk.core.CfnResource

A CloudFormation AWS::EC2::Volume.

Specifies an Amazon Elastic Block Store (Amazon EBS) volume. You can attach the volume to an instance in the same Availability Zone using AWS::EC2::VolumeAttachment .

When you use AWS CloudFormation to update an Amazon EBS volume that modifies Iops , Size , or VolumeType , there is a cooldown period before another operation can occur. This can cause your stack to report being in UPDATE_IN_PROGRESS or UPDATE_ROLLBACK_IN_PROGRESS for long periods of time.

Amazon EBS does not support sizing down an Amazon EBS volume. AWS CloudFormation does not attempt to modify an Amazon EBS volume to a smaller size on rollback.

Some common scenarios when you might encounter a cooldown period for Amazon EBS include:

  • You successfully update an Amazon EBS volume and the update succeeds. When you attempt another update within the cooldown window, that update will be subject to a cooldown period.

  • You successfully update an Amazon EBS volume and the update succeeds but another change in your update-stack call fails. The rollback will be subject to a cooldown period.

For more information on the cooldown period, see Requirements when modifying volumes .

DeletionPolicy attribute

To control how AWS CloudFormation handles the volume when the stack is deleted, set a deletion policy for your volume. You can choose to retain the volume, to delete the volume, or to create a snapshot of the volume. For more information, see DeletionPolicy attribute . .. epigraph:

If you set a deletion policy that creates a snapshot, all tags on the volume are included in the snapshot.

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_ec2 as ec2

cfn_volume = ec2.CfnVolume(self, "MyCfnVolume",
    availability_zone="availabilityZone",

    # the properties below are optional
    auto_enable_io=False,
    encrypted=False,
    iops=123,
    kms_key_id="kmsKeyId",
    multi_attach_enabled=False,
    outpost_arn="outpostArn",
    size=123,
    snapshot_id="snapshotId",
    tags=[CfnTag(
        key="key",
        value="value"
    )],
    throughput=123,
    volume_type="volumeType"
)

Create a new AWS::EC2::Volume.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

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

  • auto_enable_io (Union[bool, IResolvable, None]) – 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.

  • encrypted (Union[bool, IResolvable, None]) – Indicates 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 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 Supported instance types .

  • iops (Union[int, float, None]) – 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 : 100-64,000 IOPS io1 and io2 volumes support up to 64,000 IOPS only on Instances built on the Nitro System . Other instance families support performance up to 32,000 IOPS. This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS. This parameter is not supported for gp2 , st1 , sc1 , or standard volumes.

  • kms_key_id (Optional[str]) – The identifier of the AWS KMS key to use for Amazon EBS encryption. If KmsKeyId is specified, the encrypted state must be true . If you omit this property and your account is enabled for encryption by default, or Encrypted is set to true , then the volume is encrypted using the default key specified for your account. If your account does not have a default key, then the volume is encrypted using the AWS managed key . Alternatively, if you want to specify a different key, you can specify one of the following: - Key ID. For example, 1234abcd-12ab-34cd-56ef-1234567890ab. - Key alias. Specify the alias for the key, prefixed with alias/ . For example, for a key with the alias my_cmk , use alias/my_cmk . Or to specify the AWS managed key , use alias/aws/ebs . - Key ARN. For example, arn:aws:kms:us-east-1:012345678910:key/1234abcd-12ab-34cd-56ef-1234567890ab. - Alias ARN. For example, arn:aws:kms:us-east-1:012345678910:alias/ExampleAlias.

  • multi_attach_enabled (Union[bool, IResolvable, None]) – Indicates whether Amazon EBS Multi-Attach is enabled. AWS CloudFormation does not currently support updating a single-attach volume to be multi-attach enabled, updating a multi-attach enabled volume to be single-attach, or updating the size or number of I/O operations per second (IOPS) of a multi-attach enabled volume.

  • outpost_arn (Optional[str]) – The Amazon Resource Name (ARN) of the Outpost.

  • size (Union[int, float, None]) – The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. If you specify a snapshot, the default is the snapshot size. You can specify a volume size that is equal to or larger than the snapshot size. The following are the supported volumes sizes 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

  • snapshot_id (Optional[str]) – The snapshot from which to create the volume. You must specify either a snapshot ID or a volume size.

  • tags (Optional[Sequence[CfnTag]]) – The tags to apply to the volume during creation.

  • throughput (Union[int, float, None]) – The throughput that the volume supports, in MiB/s.

  • volume_type (Optional[str]) – The volume type. This parameter can be one of the following values:. - General Purpose SSD: gp2 | gp3 - Provisioned IOPS SSD: io1 | io2 - Throughput Optimized HDD: st1 - Cold HDD: sc1 - Magnetic: standard For more information, see Amazon EBS volume types in the Amazon Elastic Compute Cloud User Guide . Default: gp2

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

None

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

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 (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters

attribute_name (str) – The name of the attribute.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
