Implements IConstruct, IConstruct, IDependable, IInspectable

A CloudFormation AWS::EC2::SecurityGroupEgress.

Adds the specified egress rules to a security group.

An outbound rule permits instances to send traffic to the specified destination IPv4 or IPv6 CIDR address ranges, or to the specified destination security groups for the same VPC.

You specify a protocol for each rule (for example, TCP). For the TCP and UDP protocols, you must also specify the destination port or port range. For the ICMP protocol, you must also specify the ICMP type and code. You can use -1 for the type or code to mean all types or all codes.

You must specify only one of the following properties: CidrIp , CidrIpv6 , DestinationPrefixListId , or DestinationSecurityGroupId .

You must specify a destination security group ( DestinationPrefixListId or DestinationSecurityGroupId ) or a CIDR range ( CidrIp or CidrIpv6 ). If you do not specify one of these parameters, the stack will launch successfully but the rule will not be added to the security group.

Rule changes are propagated to affected instances as quickly as possible. However, a small delay might occur.

For more information about VPC security group limits, see Amazon VPC Limits .

Use AWS::EC2::SecurityGroupIngress and AWS::EC2::SecurityGroupEgress only when necessary, typically to allow security groups to reference each other in ingress and egress rules. Otherwise, use the embedded ingress and egress rules of the security group. For more information, see Amazon EC2 Security Groups .

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

addDependsOn(target)

public addDependsOn(target: CfnResource): void

Parameters

target CfnResource

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.

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 RemovalPolicy
options RemovalPolicyOptions

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).

getAtt(attributeName)

public getAtt(attributeName: string): Reference

Parameters

attributeName string — The name of the attribute.

Returns

Reference

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.)

inspect(inspector)

public inspect(inspector: TreeInspector): void

Parameters

inspector TreeInspector — - tree inspector to collect and process attributes.

Examines the CloudFormation resource and discloses attributes.

overrideLogicalId(newLogicalId)

public overrideLogicalId(newLogicalId: string): void

Parameters

newLogicalId string — The new logical ID to use for this stack element.

Overrides the auto-generated logical ID with a specific ID.

toString()

public toString(): string

Returns

string

Returns a string representation of this construct.

protected renderProperties(props)

protected renderProperties(props: { [string]: any }): { [string]: any }

Parameters

props { [string]: any }

Returns

{ [string]: any }
