Specifies an Elastic IP (EIP) address and can, optionally, associate it with an Amazon EC2 instance.
You can allocate an Elastic IP address from an address pool owned by AWS or from an address pool created from a public IPv4 address range that you have brought to AWS for use with your AWS resources using bring your own IP addresses (BYOIP). For more information, see Bring Your Own IP Addresses (BYOIP) in the Amazon EC2 User Guide .
For more information, see Elastic IP Addresses in the Amazon EC2 User Guide .

declare const listener: globalaccelerator.Listener;
declare const eip: ec2.CfnEIP;
listener.addEndpointGroup('Group', {
endpoints: [
new ga_endpoints.CfnEipEndpoint(eip, {
weight: 128,
}),
],
});

If you define an Elastic IP address and associate it with a VPC that is defined in the same template, you must declare a dependency on the VPC-gateway attachment by using the DependsOn Attribute on this resource.
instanceId?
Type:
string
(optional)
The ID of the instance.
Updates to the
InstanceId
property may require some interruptions . Updates on an EIP reassociates the address on its associated resource.
ipamPoolId?
Type:
string
(optional)
The ID of an IPAM pool which has an Amazon-provided or BYOIP public IPv4 CIDR provisioned to it.
For more information, see Allocate sequential Elastic IP addresses from an IPAM pool in the Amazon VPC IPAM User Guide .
networkBorderGroup?
Type:
string
(optional)
A unique set of Availability Zones, Local Zones, or Wavelength Zones from which AWS advertises IP addresses.
Use this parameter to limit the IP address to this location. IP addresses cannot move between network border groups.
Use DescribeAvailabilityZones to view the network border groups.
publicIpv4Pool?
Type:
string
(optional)
The ID of an address pool that you own.
Use this parameter to let Amazon EC2 select an address from the address pool.
Updates to the
PublicIpv4Pool
property may require some interruptions . Updates on an EIP reassociates the address on its associated resource.
tags?
Type:
Cfn
[]
(optional)
Any tags assigned to the Elastic IP address.
Updates to the
Tags
property may require some interruptions . Updates on an EIP reassociates the address on its associated resource.

addDeletionOverride(path)
public addDeletionOverride(path: string): void
Parameters
- path
string
— The path of the value to delete.
Syntactic sugar for addOverride(path, undefined)
.
addDependency(target)
public addDependency(target: CfnResource): void
Parameters
- target
Cfn
Resource
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.
addDependsOn(target)
public addDependsOn(target: CfnResource): void
⚠️ Deprecated: use addDependency
Parameters
- target
Cfn
Resource
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
addMetadata(key, value)
public addMetadata(key: string, value: any): void
Parameters
- key
string
- value
any
Add a value to the CloudFormation Resource Metadata.
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.](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.)
addOverride(path, value)
public addOverride(path: string, value: any): void
Parameters
- path
string
— - The path of the property, you can use dot notation to override values in complex types. - value
any
— - The 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,
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');
would add the overrides
"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.
addPropertyDeletionOverride(propertyPath)
public addPropertyDeletionOverride(propertyPath: string): void
Parameters
- propertyPath
string
— The path to the property.
Adds an override that deletes the value of a property from the resource definition.
addPropertyOverride(propertyPath, value)
public addPropertyOverride(propertyPath: string, value: any): void
Parameters
- propertyPath
string
— The path of the property. - value
any
— The value.
Adds an override to a resource property.
Syntactic sugar for addOverride("Properties.<...>", value)
.
applyRemovalPolicy(policy?, options?)
public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void
Parameters
- policy
Removal
Policy - options
Removal
Policy Options
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
). In some
cases, a snapshot can be taken of the resource prior to deletion
(RemovalPolicy.SNAPSHOT
). A list of resources that support this policy
can be found in the following link:
getAtt(attributeName, typeHint?)
public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference
Parameters
- attributeName
string
— The name of the attribute. - typeHint
Resolution
Type Hint
Returns
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.
getMetadata(key)
public getMetadata(key: string): any
Parameters
- key
string
Returns
any
Retrieve a value value from the CloudFormation Resource Metadata.
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.](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.)

Examines the CloudFormation resource and discloses attributes.
obtainDependencies()
