CfnVPCEndpoint

class aws_cdk.aws_ec2.CfnVPCEndpoint(scope, id, *, service_name, vpc_id, policy_document=None, private_dns_enabled=None, route_table_ids=None, security_group_ids=None, subnet_ids=None, vpc_endpoint_type=None)

Bases: CfnResource

A CloudFormation AWS::EC2::VPCEndpoint.

Specifies a VPC endpoint for a service. An endpoint enables you to create a private connection between your VPC and the service. The service may be provided by AWS , an AWS Marketplace Partner, or another AWS account. For more information, see the AWS PrivateLink User Guide .

An interface endpoint establishes connections between the subnets in your VPC and an AWS service, your own service, or a service hosted by another AWS account . You can specify the subnets in which to create the endpoint and the security groups to associate with the endpoint network interface.

A gateway endpoint serves as a target for a route in your route table for traffic destined for Amazon S3 or Amazon DynamoDB. You can specify an endpoint policy for the endpoint, which controls access to the service from your VPC. You can also specify the VPC route tables that use the endpoint. For information about connectivity to Amazon S3, see Why can’t I connect to an S3 bucket using a gateway VPC endpoint?

A Gateway Load Balancer endpoint provides private connectivity between your VPC and virtual appliances from a service provider.

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_ec2 as ec2

# policy_document: Any

cfn_vPCEndpoint = ec2.CfnVPCEndpoint(self, "MyCfnVPCEndpoint",
    service_name="serviceName",
    vpc_id="vpcId",

    # the properties below are optional
    policy_document=policy_document,
    private_dns_enabled=False,
    route_table_ids=["routeTableIds"],
    security_group_ids=["securityGroupIds"],
    subnet_ids=["subnetIds"],
    vpc_endpoint_type="vpcEndpointType"
)

Create a new AWS::EC2::VPCEndpoint.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • service_name (str) – The service name. To list the available services, use DescribeVpcEndpointServices . Otherwise, get the name from the service provider.

  • vpc_id (str) – The ID of the VPC in which the endpoint will be used.

  • policy_document (Optional[Any]) – A policy that controls access to the service from the VPC. If this parameter is not specified, the default policy allows full access to the service. Endpoint policies are supported only for gateway and interface endpoints. For CloudFormation templates in YAML, you can provide the policy in JSON or YAML format. AWS CloudFormation converts YAML policies to JSON format before calling the API to create or modify the VPC endpoint.

  • private_dns_enabled (Union[bool, IResolvable, None]) – Indicate whether to associate a private hosted zone with the specified VPC. The private hosted zone contains a record set for the default public DNS name for the service for the Region (for example, kinesis.us-east-1.amazonaws.com ), which resolves to the private IP addresses of the endpoint network interfaces in the VPC. This enables you to make requests to the default public DNS name for the service instead of the public DNS names that are automatically generated by the VPC endpoint service. To use a private hosted zone, you must set the following VPC attributes to true : enableDnsHostnames and enableDnsSupport . This property is supported only for interface endpoints. Default: false

  • route_table_ids (Optional[Sequence[str]]) – The route table IDs. Routing is supported only for gateway endpoints.

  • security_group_ids (Optional[Sequence[str]]) – The IDs of the security groups to associate with the endpoint network interface. Security groups are supported only for interface endpoints.

  • subnet_ids (Optional[Sequence[str]]) – The ID of the subnets in which to create an endpoint network interface. You must specify this property for an interface endpoints or a Gateway Load Balancer endpoint. You can’t specify this property for a gateway endpoint. For a Gateway Load Balancer endpoint, you can specify only one subnet.

  • vpc_endpoint_type (Optional[str]) – The type of endpoint. Default: Gateway

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:

# Example automatically generated from non-compiling source. May contain errors.
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). 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: 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.

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

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

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

Any

inspect(inspector)

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(construct)

Check whether the given construct is a CfnResource.

Parameters

construct (IConstruct) –

Return type

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct 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 class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof 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 the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, 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 extends Construct.
