Constructors

Properties

allowAllIpv6Outbound: boolean

Whether the SecurityGroup has been configured to allow all outbound ipv6 traffic

allowAllOutbound: boolean

Whether the SecurityGroup has been configured to allow all outbound traffic

canInlineRule: false = false
connections: Connections
defaultPort?: Port
env: ResourceEnvironment
idWithApp: string

The ID of the construct with the App suffix. This should be used in place of id when trying to reference the construct.

node: Node

The tree node.

physicalName: string

Returns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.

This value will resolve to one of the following:

  • a concrete value (e.g. "my-awesome-bucket")
  • undefined, when a name should be generated by CloudFormation
  • a concrete name generated automatically during synthesis, in cross-environment scenarios.
securityGroupId: string

The ID of the security group

Attribute

securityGroupVpcId: string

The VPC ID this security group is part of.

Attribute

stack: Stack

Accessors

  • get uniqueId(): string
  • Returns string

Methods

  • Internal

    Called when this resource is referenced across environments (account/region) to order to request that a physical name will be generated for this resource during synthesis, so the resource can be referenced through its absolute name/arn.

    Returns void

  • Parameters

    • peer: IPeer
    • connection: Port
    • Optional description: string
    • Optional remoteRule: boolean

    Returns void

  • Parameters

    • peer: IPeer
    • connection: Port
    • Optional description: string
    • Optional remoteRule: boolean

    Returns void

  • Apply the given removal policy to this resource

    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: RemovalPolicy

    Returns void

  • Determine where to parent a new ingress/egress rule

    A SecurityGroup rule is parented under the group it's related to, UNLESS we're in a cross-stack scenario with another Security Group. In that case, we respect the 'remoteRule' flag and will parent under the other security group.

    This is necessary to avoid cyclic dependencies between stacks, since both ingress and egress rules will reference both security groups, and a naive parenting will lead to the following situation:

    ╔════════════════════╗ ╔════════════════════╗ ║ ┌───────────┐ ║ ║ ┌───────────┐ ║ ║ │ GroupA │◀────╬─┐ ┌───╬───▶│ GroupB │ ║ ║ └───────────┘ ║ │ │ ║ └───────────┘ ║ ║ ▲ ║ │ │ ║ ▲ ║ ║ │ ║ │ │ ║ │ ║ ║ │ ║ │ │ ║ │ ║ ║ ┌───────────┐ ║ └───┼───╬────┌───────────┐ ║ ║ │ EgressA │─────╬─────┘ ║ │ IngressB │ ║ ║ └───────────┘ ║ ║ └───────────┘ ║ ║ ║ ║ ║ ╚════════════════════╝ ╚════════════════════╝

    By having the ability to switch the parent, we avoid the cyclic reference by keeping all rules in a single stack.

    If this happens, we also have to change the construct ID, because otherwise we might have two objects with the same ID if we have multiple reversed security group relationships.

    ╔═══════════════════════════════════╗ ║┌───────────┐ ║ ║│ GroupB │ ║ ║└───────────┘ ║ ║ ▲ ║ ║ │ ┌───────────┐ ║ ║ ├────"from A"──│ IngressB │ ║ ║ │ └───────────┘ ║ ║ │ ┌───────────┐ ║ ║ ├─────"to B"───│ EgressA │ ║ ║ │ └───────────┘ ║ ║ │ ┌───────────┐ ║ ║ └─────"to B"───│ EgressC │ ║ <-- oops ║ └───────────┘ ║ ╚═══════════════════════════════════╝

    Parameters

    • peer: IPeer
    • connection: Port
    • fromTo: "from" | "to"
    • Optional remoteRule: boolean

    Returns RuleScope

  • Returns an environment-sensitive token that should be used for the resource's "ARN" attribute (e.g. bucket.bucketArn).

    Normally, this token will resolve to arnAttr, but if the resource is referenced across environments, arnComponents will be used to synthesize a concrete ARN with the resource's physical name. Make sure to reference this.physicalName in arnComponents.

    Parameters

    • arnAttr: string

      The CFN attribute which resolves to the ARN of the resource. Commonly it will be called "Arn" (e.g. resource.attrArn), but sometimes it's the CFN resource's ref.

    • arnComponents: ArnComponents

      The format of the ARN of this resource. You must reference this.physicalName somewhere within the ARN in order for cross-environment references to work.

    Returns string

  • Returns an environment-sensitive token that should be used for the resource's "name" attribute (e.g. bucket.bucketName).

    Normally, this token will resolve to nameAttr, but if the resource is referenced across environments, it will be resolved to this.physicalName, which will be a concrete name.

    Parameters

    • nameAttr: string

      The CFN attribute which resolves to the resource's name. Commonly this is the resource's ref.

    Returns string

  • Returns a string representation of an object.

    Returns string

  • Look up a security group by id.

    Parameters

    • scope: Construct
    • id: string
    • securityGroupId: string

    Returns ISecurityGroup

  • Look up a security group by name.

    Parameters

    • scope: Construct
    • id: string
    • securityGroupName: string
    • vpc: IVpc

    Returns ISecurityGroup

  • Import an existing security group into this app.

    This method will assume that the Security Group has a rule in it which allows all outbound traffic, and so will not add egress rules to the imported Security Group (only ingress rules).

    If your existing Security Group needs to have egress rules added, pass the allowAllOutbound: false option on import.

    Parameters

    • scope: Construct
    • id: string
    • securityGroupId: string
    • Optional options: SecurityGroupImportOptions

    Returns ISecurityGroup

  • 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

    Returns x is Construct

    true if x is an object created from a class which extends Construct.

  • Returns true if the construct was created by CDK, and false otherwise

    Parameters

    • construct: IConstruct

    Returns boolean

  • Check whether the given construct is a Resource

    Parameters

    • construct: IConstruct

    Returns construct is Resource

  • Return whether the indicated object is a security group

    Parameters

    • x: any

    Returns x is SecurityGroupBase
