# CreateComponent
<a name="API_CreateComponent"></a>

Creates a new component that can be used to build, validate, test, and assess your image. The component is based on a YAML document that you specify using exactly one of the following methods:
+ Inline, using the `data` property in the request body.
+ A URL that points to a YAML document file stored in Amazon S3, using the `uri` property in the request body.

Image Builder determines the component type from the document. If the document contains a single phase named `test`, the component type is `TEST`. Otherwise, the component type is `BUILD`.

## URI Request Parameters
<a name="API_CreateComponent_RequestParameters"></a>

The request does not use any URI parameters.

## Request Body
<a name="API_CreateComponent_RequestBody"></a>

The request accepts the following data in JSON format.

 ** [changeDescription](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-changeDescription"></a>
The change description of the component. Describes what change has been made in this version, or what makes this version different from other versions of the component.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 1024.  
Required: No

 ** [clientToken](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-clientToken"></a>
A unique, case-sensitive identifier you provide to ensure that the operation runs no more than one time. If you retry a request with the same client token, Image Builder returns the original response without running the operation again. For more information, see [Ensuring idempotency](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/Run_Instance_Idempotency.html) in the *Amazon EC2 API Reference*.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.  
Required: Yes

 ** [data](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-data"></a>
Component `data` contains inline YAML document content for the component. Alternatively, you can specify the `uri` of a YAML document file stored in Amazon S3. However, you cannot specify both properties.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 16000.  
Pattern: `[^\x00]+`   
Required: No

 ** [description](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-description"></a>
Describes the contents of the component.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 1024.  
Required: No

 ** [dryRun](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-dryRun"></a>
Validates the required permissions and request parameters without performing the operation. If validation succeeds, the operation returns a `DryRunOperationException` error response.  
Type: Boolean  
Required: No

 ** [kmsKeyId](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-kmsKeyId"></a>
The Amazon Resource Name (ARN) that uniquely identifies the KMS key used to encrypt this component. This can be either the Key ARN or the Alias ARN. For more information, see [Key identifiers (KeyId)](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#key-id-key-ARN) in the * AWS Key Management Service Developer Guide*. If you don't specify a key, Image Builder encrypts the component data with a KMS key that Image Builder owns.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 1024.  
Required: No

 ** [name](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-name"></a>
The name of the component. Image Builder generates the component ARN from a normalized form of the name, so names that differ only in case, spaces, or underscores count as the same name. If a component with the same name and semantic version already exists in your account in the same AWS Region, the request creates a new build version for it. If the content is also identical to the latest build version, the request fails because the component already exists.  
Type: String  
Pattern: `^[-_A-Za-z-0-9][-_A-Za-z0-9 ]{1,126}[-_A-Za-z-0-9]$`   
Required: Yes

 ** [platform](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-platform"></a>
The operating system platform of the component.  
Type: String  
Valid Values: `Windows | Linux | macOS`   
Required: Yes

 ** [semanticVersion](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-semanticVersion"></a>
The semantic version of the component. This version follows the semantic version syntax.  
The semantic version has four nodes: <major>.<minor>.<patch>/<build>. You can assign values for the first three, and can filter on all of them.  
 **Assignment:** For the first three nodes, you can assign any positive integer value, including zero. The upper limit is 2^30-1, or 1073741823, for each node. Image Builder automatically assigns the build number to the fourth node.  
 **Patterns:** You can use any numeric pattern that adheres to the assignment requirements for the nodes that you can assign. For example, you might choose a software version pattern, such as 1.0.0, or a date, such as 2021.01.01.
Type: String  
Pattern: `^[0-9]+\.[0-9]+\.[0-9]+$`   
Required: Yes

 ** [supportedOsVersions](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-supportedOsVersions"></a>
The operating system (OS) version supported by the component. If the OS information is available, a prefix match is performed against the base image OS version during image recipe creation.  
Type: Array of strings  
Array Members: Minimum number of 1 item. Maximum number of 25 items.  
Length Constraints: Minimum length of 1.  
Required: No

 ** [tags](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-tags"></a>
The tags that apply to the component.  
Type: String to string map  
Map Entries: Maximum number of 50 items.  
Key Length Constraints: Minimum length of 1. Maximum length of 128.  
Key Pattern: `^(?!aws:)[a-zA-Z0-9\s_.:/=+\-@]*$`   
Value Length Constraints: Maximum length of 256.  
Required: No

 ** [uri](#API_CreateComponent_RequestSyntax) **   <a name="imagebuilder-CreateComponent-request-uri"></a>
The `uri` of a YAML component document file. This must be an S3 URL (`s3://bucket/key`), and you must have permission to access the S3 bucket it points to. If you use Amazon S3, you can specify component content up to your service quota for component size, which is 64 KB by default.  
Alternatively, you can specify the YAML document inline, using the component `data` property. You cannot specify both properties.  
Type: String  
Required: No
