CfnDocument

The content for the new SSM document in JSON or YAML. For more information about the schemas for SSM document content, see [SSM document schema features and examples](https://docs.aws.amazon.com/systems-manager/latest/userguide/document-schemas-features.html) in the *AWS Systems Manager User Guide* . > This parameter also supports `String` data types.

A list of key-value pairs that describe attachments to a version of a document.

Specify the document format for the request. `JSON` is the default format.

Default: - "JSON"

The type of document to create.

A name for the SSM document. > You can't use the following strings as document name prefixes. These are reserved by AWS for use as document name prefixes: > > - `aws` > - `amazon` > - `amzn` > - `AWSEC2` > - `AWSConfigRemediation` > - `AWSSupport`

A list of SSM documents required by a document. This parameter is used exclusively by AWS AppConfig . When a user creates an AWS AppConfig configuration in an SSM document, the user must also specify a required document for validation purposes. In this case, an `ApplicationConfiguration` document requires an `ApplicationConfigurationSchema` document for validation purposes. For more information, see [What is AWS AppConfig ?](https://docs.aws.amazon.com/appconfig/latest/userguide/what-is-appconfig.html) in the *AWS AppConfig User Guide* .

AWS CloudFormation resource tags to apply to the document. Use tags to help you identify and categorize resources.

Specify a target type to define the kinds of resources the document can run on. For example, to run a document on EC2 instances, specify the following value: `/AWS::EC2::Instance` . If you specify a value of '/' the document can run on all types of resources. If you don't specify a value, the document can't run on any resources. For a list of valid resource types, see [AWS resource and property types reference](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-template-resource-type-ref.html) in the *AWS CloudFormation User Guide* .

If the document resource you specify in your template already exists, this parameter determines whether a new version of the existing document is created, or the existing document is replaced. `Replace` is the default method. If you specify `NewVersion` for the `UpdateMethod` parameter, and the `Name` of the document does not match an existing resource, a new document is created. When you specify `NewVersion` , the default version of the document is changed to the newly created version.

Default: - "Replace"

An optional field specifying the version of the artifact you are creating with the document. For example, `Release12.1` . This value is unique across all versions of a document, and can't be changed.
