- ExampleMetadata:
fixture=_generated
Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. from aws_cdk import aws_globalaccelerator as globalaccelerator cfn_endpoint_group = globalaccelerator.CfnEndpointGroup(self, "MyCfnEndpointGroup", endpoint_group_region="endpointGroupRegion", listener_arn="listenerArn", # the properties below are optional endpoint_configurations=[globalaccelerator.CfnEndpointGroup.EndpointConfigurationProperty( endpoint_id="endpointId", # the properties below are optional attachment_arn="attachmentArn", client_ip_preservation_enabled=False, weight=123 )], health_check_interval_seconds=123, health_check_path="healthCheckPath", health_check_port=123, health_check_protocol="healthCheckProtocol", port_overrides=[globalaccelerator.CfnEndpointGroup.PortOverrideProperty( endpoint_port=123, listener_port=123 )], threshold_count=123, traffic_dial_percentage=123 )
- Parameters:
scope (
Construct
) – Scope in which this resource is defined.id (
str
) – Construct identifier for this resource (unique in its scope).endpoint_group_region (
str
) – The AWS Regions where the endpoint group is located.listener_arn (
str
) – The Amazon Resource Name (ARN) of the listener.endpoint_configurations (
Union
[IResolvable
,Sequence
[Union
[IResolvable
,EndpointConfigurationProperty
,Dict
[str
,Any
]]],None
]) – The list of endpoint objects.health_check_interval_seconds (
Union
[int
,float
,None
]) – The time—10 seconds or 30 seconds—between health checks for each endpoint. The default value is 30. Default: - 30health_check_path (
Optional
[str
]) – If the protocol is HTTP/S, then this value provides the ping path that Global Accelerator uses for the destination on the endpoints for health checks. The default is slash (/). Default: - “/”health_check_port (
Union
[int
,float
,None
]) – The port that Global Accelerator uses to perform health checks on endpoints that are part of this endpoint group. The default port is the port for the listener that this endpoint group is associated with. If the listener port is a list, Global Accelerator uses the first specified port in the list of ports. Default: - -1health_check_protocol (
Optional
[str
]) – The protocol that Global Accelerator uses to perform health checks on endpoints that are part of this endpoint group. The default value is TCP. Default: - “TCP”port_overrides (
Union
[IResolvable
,Sequence
[Union
[IResolvable
,PortOverrideProperty
,Dict
[str
,Any
]]],None
]) – Allows you to override the destination ports used to route traffic to an endpoint. Using a port override lets you map a list of external destination ports (that your users send traffic to) to a list of internal destination ports that you want an application endpoint to receive traffic on.threshold_count (
Union
[int
,float
,None
]) – The number of consecutive health checks required to set the state of a healthy endpoint to unhealthy, or to set an unhealthy endpoint to healthy. The default value is 3. Default: - 3traffic_dial_percentage (
Union
[int
,float
,None
]) – The percentage of traffic to send to an AWS Regions . Additional traffic is distributed to other endpoint groups for this listener. Use this action to increase (dial up) or decrease (dial down) traffic to a specific Region. The percentage is applied to the traffic that would otherwise have been routed to the Region based on optimal routing. The default value is 100. Default: - 100
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_dependency(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_depends_on(target)
(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
- Parameters:
target (
CfnResource
) –- Deprecated:
use addDependency
- Stability:
deprecated
- Return type:
None
- add_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
) –value (
Any
) –
- See:
- Return type:
None
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.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
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 toaddOverride
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 intermediate 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
). 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:- Parameters:
policy (
Optional
[RemovalPolicy
]) –apply_to_update_replace_policy (
Optional
[bool
]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: truedefault (
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 resource, please consult that specific resource’s documentation.
- See:
- Return type:
None
- get_att(attribute_name, type_hint=None)
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:

str
) – The name of the attribute.type_hint (
Optional
[ResolutionTypeHint
]) –

Static Methods
- classmethod is_cfn_element(x)
Returns
true
if a construct is a stack element (i.e. part of the synthesized cloudformation template).Uses duck-typing instead of
instanceof
to allow stack elements from different versions of this library to be included in the same stack.- Parameters:
x (
Any
) –- Return type:
bool
- Returns:
The construct as a stack element or undefined if it is not a stack element.
- classmethod is_cfn_resource(x)
Check whether the given object is a CfnResource.
- Parameters:
x (
Any
) –- Return type:
bool
- classmethod is_construct(x)
Checks if
x
is a construct.Use this method instead of
instanceof
to properly detectConstruct
instances, even when the construct library is symlinked.Explanation: in JavaScript, multiple copies of the
constructs
library on disk are seen as independent, completely different libraries. As a consequence, the classConstruct
in each copy of theconstructs
library is seen as a different class, and an instance of one class will not test asinstanceof
the other class.npm install
will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of theconstructs
library can be accidentally installed, andinstanceof
will behave unpredictably. It is safest to avoid usinginstanceof
, and using this type-testing method instead.- Parameters:
x (
Any
) – Any object.- Return type:
bool
- Returns:
true if
x
is an object created from a class which extendsConstruct
.
EndpointConfigurationProperty
- class CfnEndpointGroup.EndpointConfigurationProperty(*, endpoint_id, attachment_arn=None, client_ip_preservation_enabled=None, weight=None)
Bases:
object
A complex type for endpoints.
A resource must be valid and active when you add it as an endpoint.
- Parameters:
endpoint_id (
str
) – An ID for the endpoint. If the endpoint is a Network Load Balancer or Application Load Balancer, this is the Amazon Resource Name (ARN) of the resource. If the endpoint is an Elastic IP address, this is the Elastic IP address allocation ID. For Amazon EC2 instances, this is the EC2 instance ID. A resource must be valid and active when you add it as an endpoint. For cross-account endpoints, this must be the ARN of the resource.attachment_arn (
Optional
[str
]) – The Amazon Resource Name (ARN) of the cross-account attachment that specifies the endpoints (resources) that can be added to accelerators and principals that have permission to add the endpoints.client_ip_preservation_enabled (
Union
[bool
,IResolvable
,None
]) – Indicates whether client IP address preservation is enabled for an Application Load Balancer endpoint. The value is true or false. The default value is true for new accelerators. If the value is set to true, the client’s IP address is preserved in theX-Forwarded-For
request header as traffic travels to applications on the Application Load Balancer endpoint fronted by the accelerator. For more information, see Preserve Client IP Addresses in the AWS Global Accelerator Developer Guide . Default: - trueweight (
Union
[int
,float
,None
]) – The weight associated with the endpoint. When you add weights to endpoints, you configure Global Accelerator to route traffic based on proportions that you specify. For example, you might specify endpoint weights of 4, 5, 5, and 6 (sum=20). The result is that 4/20 of your traffic, on average, is routed to the first endpoint, 5/20 is routed both to the second and third endpoints, and 6/20 is routed to the last endpoint. For more information, see Endpoint Weights in the AWS Global Accelerator Developer Guide . Default: - 100
- See:
- ExampleMetadata:
fixture=_generated
Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. from aws_cdk import aws_globalaccelerator as globalaccelerator endpoint_configuration_property = globalaccelerator.CfnEndpointGroup.EndpointConfigurationProperty( endpoint_id="endpointId", # the properties below are optional attachment_arn="attachmentArn", client_ip_preservation_enabled=False, weight=123 )
Attributes
- attachment_arn
The Amazon Resource Name (ARN) of the cross-account attachment that specifies the endpoints (resources) that can be added to accelerators and principals that have permission to add the endpoints.
- client_ip_preservation_enabled
Indicates whether client IP address preservation is enabled for an Application Load Balancer endpoint.
The value is true or false. The default value is true for new accelerators.
If the value is set to true, the client’s IP address is preserved in the
X-Forwarded-For
request header as traffic travels to applications on the Application Load Balancer endpoint fronted by the accelerator.For more information, see Preserve Client IP Addresses in the AWS Global Accelerator Developer Guide .
- endpoint_id
An ID for the endpoint.
If the endpoint is a Network Load Balancer or Application Load Balancer, this is the Amazon Resource Name (ARN) of the resource. If the endpoint is an Elastic IP address, this is the Elastic IP address allocation ID. For Amazon EC2 instances, this is the EC2 instance ID. A resource must be valid and active when you add it as an endpoint.
For cross-account endpoints, this must be the ARN of the resource.
- weight
The weight associated with the endpoint.
When you add weights to endpoints, you configure Global Accelerator to route traffic based on proportions that you specify. For example, you might specify endpoint weights of 4, 5, 5, and 6 (sum=20). The result is that 4/20 of your traffic, on average, is routed to the first endpoint, 5/20 is routed both to the second and third endpoints, and 6/20 is routed to the last endpoint. For more information, see Endpoint Weights in the AWS Global Accelerator Developer Guide .
PortOverrideProperty
- class CfnEndpointGroup.PortOverrideProperty(*, endpoint_port, listener_port)
Bases:
object
Override specific listener ports used to route traffic to endpoints that are part of an endpoint group.
For example, you can create a port override in which the listener receives user traffic on ports 80 and 443, but your accelerator routes that traffic to ports 1080 and 1443, respectively, on the endpoints.
For more information, see Port overrides in the AWS Global Accelerator Developer Guide .
