CfnSecurityGroup

class aws_cdk.aws_ec2.CfnSecurityGroup(scope, id, *, group_description, group_name=None, security_group_egress=None, security_group_ingress=None, tags=None, vpc_id=None)

Bases: CfnResource

A CloudFormation AWS::EC2::SecurityGroup.

Specifies a security group. To create a security group, use the VpcId property to specify the VPC for which to create the security group.

This type supports updates. For more information about updating stacks, see AWS CloudFormation Stacks Updates . .. epigraph:

To cross-reference two security groups in the ingress and egress rules of those security groups, use the `AWS::EC2::SecurityGroupEgress <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-security-group-egress.html>`_ and `AWS::EC2::SecurityGroupIngress <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-security-group-ingress.html>`_ resources to define your rules. Do not use the embedded ingress and egress rules in the ``AWS::EC2::SecurityGroup`` . Doing so creates a circular dependency, which AWS CloudFormation doesn't allow.

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

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.

EgressProperty

class CfnSecurityGroup.EgressProperty(*, ip_protocol, cidr_ip=None, cidr_ipv6=None, description=None, destination_prefix_list_id=None, destination_security_group_id=None, from_port=None, to_port=None)

Bases: object

[EC2-VPC only] Adds the specified egress rules to a security group for use with a VPC.

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 SecurityGroup.Ingress and SecurityGroup.Egress 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 .

The EC2 Security Group Rule is an embedded property of the AWS::EC2::SecurityGroup type.

Parameters
  • ip_protocol (str) – The IP protocol name ( tcp , udp , icmp , icmpv6 ) or number (see Protocol Numbers ). [VPC only] Use -1 to specify all protocols. When authorizing security group rules, specifying -1 or a protocol number other than tcp , udp , icmp , or icmpv6 allows traffic on all ports, regardless of any port range you specify. For tcp , udp , and icmp , you must specify a port range. For icmpv6 , the port range is optional; if you omit the port range, traffic for all types and codes is allowed.

  • cidr_ip (Optional[str]) – The IPv4 address range, in CIDR format. You must specify a destination security group ( DestinationPrefixListId or DestinationSecurityGroupId ) or a CIDR range ( CidrIp or CidrIpv6 ). For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases in the Amazon EC2 User Guide .

  • cidr_ipv6 (Optional[str]) –

    The IPv6 address range, in CIDR format. You must specify a destination security group ( DestinationPrefixListId or DestinationSecurityGroupId ) or a CIDR range ( CidrIp or CidrIpv6 ). For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases in the Amazon EC2 User Guide .

  • description (Optional[str]) – A description for the security group rule. Constraints: Up to 255 characters in length. Allowed characters are a-z, A-Z, 0-9, spaces, and ._-:/()#,@[]+=;{}!$*

  • destination_prefix_list_id (Optional[str]) – [EC2-VPC only] The prefix list IDs for the destination AWS service. This is the AWS service that you want to access through a VPC endpoint from instances associated with the security group. You must specify a destination security group ( DestinationPrefixListId or DestinationSecurityGroupId ) or a CIDR range ( CidrIp or CidrIpv6 ).

  • destination_security_group_id (Optional[str]) – The ID of the destination VPC security group. You must specify a destination security group ( DestinationPrefixListId or DestinationSecurityGroupId ) or a CIDR range ( CidrIp or CidrIpv6 ).

  • from_port (Union[int, float, None]) – The start of port range for the TCP and UDP protocols, or an ICMP/ICMPv6 type number. A value of -1 indicates all ICMP/ICMPv6 types. If you specify all ICMP/ICMPv6 types, you must specify all codes.

  • to_port (Union[int, float, None]) – The end of port range for the TCP and UDP protocols, or an ICMP/ICMPv6 code. A value of -1 indicates all ICMP/ICMPv6 codes. If you specify all ICMP/ICMPv6 types, you must specify all codes.
