import aws_cdk.aws_ec2 as ec2

cfn_network_interface = ec2.CfnNetworkInterface(self, "MyCfnNetworkInterface",

)

Create a new AWS::EC2::NetworkInterface.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
subnet_id (str) – The ID of the subnet to associate with the network interface.
description (Optional[str]) – A description for the network interface.
group_set (Optional[Sequence[str]]) – The security group IDs associated with this network interface.
interface_type (Optional[str]) – The type of network interface. The default is interface . The supported values are efa and trunk .
ipv6_address_count (Union[int, float, None]) – The number of IPv6 addresses to assign to a network interface. Amazon EC2 automatically selects the IPv6 addresses from the subnet range. To specify specific IPv6 addresses, use the Ipv6Addresses property and don’t specify this property.
ipv6_addresses (Union[IResolvable, Sequence[Union[IResolvable, InstanceIpv6AddressProperty, Dict[str, Any]]], None]) – One or more specific IPv6 addresses from the IPv6 CIDR block range of your subnet to associate with the network interface. If you’re specifying a number of IPv6 addresses, use the Ipv6AddressCount property and don’t specify this property.
private_ip_address (Optional[str]) – Assigns a single private IP address to the network interface, which is used as the primary private IP address. If you want to specify multiple private IP address, use the PrivateIpAddresses property.
private_ip_addresses (Union[IResolvable, Sequence[Union[IResolvable, PrivateIpAddressSpecificationProperty, Dict[str, Any]]], None]) – Assigns private IP addresses to the network interface. You can specify a primary private IP address by setting the value of the Primary property to true in the PrivateIpAddressSpecification property. If you want EC2 to automatically assign private IP addresses, use the SecondaryPrivateIpAddressCount property and do not specify this property.
secondary_private_ip_address_count (Union[int, float, None]) – The number of secondary private IPv4 addresses to assign to a network interface. When you specify a number of secondary IPv4 addresses, Amazon EC2 selects these IP addresses within the subnet’s IPv4 CIDR range. You can’t specify this option and specify more than one private IP address using privateIpAddresses . You can’t specify a count of private IPv4 addresses if you’ve specified one of the following: specific private IPv4 addresses, specific IPv4 prefixes, or a count of IPv4 prefixes.
source_dest_check (Union[bool, IResolvable, None]) – Enable or disable source/destination checks, which ensure that the instance is either the source or the destination of any traffic that it receives. If the value is true , source/destination checks are enabled; otherwise, they are disabled. The default value is true . You must disable source/destination checks if the instance runs services such as network address translation, routing, or firewalls.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – An arbitrary set of tags (key-value pairs) for this network interface.

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:

Return type:

None

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.

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:

Return type:

Any

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.

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None
