CfnParameter

class aws_cdk.aws_ssm.CfnParameter(scope, id, *, type, value, allowed_pattern=None, data_type=None, description=None, name=None, policies=None, tags=None, tier=None)

Bases: CfnResource

A CloudFormation AWS::SSM::Parameter.

The AWS::SSM::Parameter resource creates an SSM parameter in AWS Systems Manager Parameter Store. .. epigraph:

To create an SSM parameter, you must have the AWS Identity and Access Management ( IAM ) permissions ``ssm:PutParameter`` and ``ssm:AddTagsToResource`` . On stack creation, AWS CloudFormation adds the following three tags to the parameter: ``aws:cloudformation:stack-name`` , ``aws:cloudformation:logical-id`` , and ``aws:cloudformation:stack-id`` , in addition to any custom tags you specify.

To add, update, or remove tags during stack update, you must have IAM permissions for both ``ssm:AddTagsToResource`` and ``ssm:RemoveTagsFromResource`` . For more information, see `Managing Access Using Policies <https://docs.aws.amazon.com/systems-manager/latest/userguide/security-iam.html#security_iam_access-manage>`_ in the *AWS Systems Manager User Guide* .

For information about valid values for parameters, see Requirements and Constraints for Parameter Names in the AWS Systems Manager User Guide and PutParameter in the AWS Systems Manager API Reference .

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_ssm as ssm

# tags: Any

cfn_parameter = ssm.CfnParameter(self, "MyCfnParameter",

    tier="tier"
)

Create a new AWS::SSM::Parameter.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
type (str) – The type of parameter. .. epigraph:: AWS CloudFormation doesn’t support creating a SecureString parameter type. Allowed Values : String | StringList
value (str) – The parameter value. .. epigraph:: If type is StringList , the system returns a comma-separated string with no spaces between commas in the Value field.
allowed_pattern (Optional[str]) – A regular expression used to validate the parameter value. For example, for String types with values restricted to numbers, you can specify the following: AllowedPattern=^\d+$
data_type (Optional[str]) – The data type of the parameter, such as text or aws:ec2:image . The default is text .
description (Optional[str]) – Information about the parameter.
name (Optional[str]) – The name of the parameter. .. epigraph:: The maximum length constraint listed below includes capacity for additional system attributes that aren’t part of the name. The maximum length for a parameter name, including the full length of the parameter ARN, is 1011 characters. For example, the length of the following parameter name is 65 characters, not 20 characters: arn:aws:ssm:us-east-2:111222333444:parameter/ExampleParameterName
policies (Optional[str]) – Information about the policies assigned to a parameter. Assigning parameter policies in the AWS Systems Manager User Guide .
tags (Optional[Any]) – Optional metadata that you assign to a resource in the form of an arbitrary set of tags (key-value pairs). Tags enable you to categorize a resource in different ways, such as by purpose, owner, or environment. For example, you might want to tag a Systems Manager parameter to identify the type of resource to which it applies, the environment, or the type of configuration data referenced by the parameter.
tier (Optional[str]) – The parameter tier.

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

override_logical_id(new_logical_id)

Parameters:: new_logical_id (str) – The new logical ID to use for this stack element.
Return type:: None

to_string()

Returns a string representation of this construct.

Return type:: str
Returns:: a string representation of this resource

Attributes

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ssm-parameter.html#cfn-ssm-parameter-description

logical_id

The logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

name

The name of the parameter.

The maximum length constraint listed below includes capacity for additional system attributes that aren’t part of the name. The maximum length for a parameter name, including the full length of the parameter ARN, is 1011 characters.

The stack in which this element is defined.

CfnElements must be defined within a stack scope (directly or indirectly).

tags

Optional metadata that you assign to a resource in the form of an arbitrary set of tags (key-value pairs).

Tags enable you to categorize a resource in different ways, such as by purpose, owner, or environment. For example, you might want to tag a Systems Manager parameter to identify the type of resource to which it applies, the environment, or the type of configuration data referenced by the parameter.
