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_dependency(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_depends_on(target)

(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

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 intermediate 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 resource, 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, type_hint=None)

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.

  • type_hint (Optional[ResolutionTypeHint]) –

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.

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(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

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.

FirewallRuleProperty

class CfnFirewallRuleGroup.FirewallRuleProperty(*, action, firewall_domain_list_id, priority, block_override_dns_type=None, block_override_domain=None, block_override_ttl=None, block_response=None, firewall_domain_redirection_action=None, qtype=None)

Bases: object

If this is specified,then BlockResponse must also be specified. if BlockResponse is OVERRIDE , then all of the following OVERRIDE attributes must be specified: - BlockOverrideDnsType - BlockOverrideDomain - BlockOverrideTtl

  • firewall_domain_list_id (str) – The ID of the domain list that’s used in the rule.

  • priority (Union[int, float]) – The priority of the rule in the rule group. This value must be unique within the rule group. DNS Firewall processes the rules in a rule group by order of priority, starting from the lowest setting.

  • block_override_dns_type (Optional[str]) – The DNS record’s type. This determines the format of the record value that you provided in BlockOverrideDomain . Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

  • block_override_ttl (Union[int, float, None]) – The recommended amount of time, in seconds, for the DNS resolver or web browser to cache the provided override record. Used for the rule action BLOCK with a BlockResponse setting of OVERRIDE .

  • block_response (Optional[str]) – The way that you want DNS Firewall to block the request. Used for the rule action setting BLOCK . - NODATA - Respond indicating that the query was successful, but no response is available for it. - NXDOMAIN - Respond indicating that the domain name that’s in the query doesn’t exist. - OVERRIDE - Provide a custom override in the response. This option requires custom handling details in the rule’s BlockOverride* settings.

  • firewall_domain_redirection_action (Optional[str]) – How you want the the rule to evaluate DNS redirection in the DNS redirection chain, such as CNAME, or DNAME. Inspect_Redirection_Domain (Default) inspects all domains in the redirection chain. The individual domains in the redirection chain must be added to the domain list. Trust_Redirection_Domain inspects only the first domain in the redirection chain. You don’t need to add the subsequent domains in the domain in the redirection list to the domain list.

  • qtype (Optional[str]) – The DNS query type you want the rule to evaluate. Allowed values are; - A: Returns an IPv4 address. - AAAA: Returns an Ipv6 address. - CAA: Restricts CAs that can create SSL/TLS certifications for the domain. - CNAME: Returns another domain name. - DS: Record that identifies the DNSSEC signing key of a delegated zone. - MX: Specifies mail servers. - NAPTR: Regular-expression-based rewriting of domain names. - NS: Authoritative name servers. - PTR: Maps an IP address to a domain name. - SOA: Start of authority record for the zone. - SPF: Lists the servers authorized to send emails from a domain. - SRV: Application specific values that identify servers. - TXT: Verifies email senders and application-specific values. - A query type you define by using the DNS type ID, for example 28 for AAAA. The values must be defined as TYPE NUMBER , where the NUMBER can be 1-65334, for example, TYPE28. For more information, see List of DNS record types .
