# CfnComponent

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.

Extends: Construct › CfnElement › CfnRefElement › CfnResource › CfnComponent
Implements: IInspectable, ITaggable, IEnvironmentAware, IComponentRef, IConstruct, IDependable

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_imagebuilder as imagebuilder } from 'aws-cdk-lib';
const cfnComponent = new imagebuilder.CfnComponent(this, 'MyCfnComponent', {
  name: 'name',
  platform: 'platform',
  version: 'version',

  // the properties below are optional
  changeDescription: 'changeDescription',
  data: 'data',
  description: 'description',
  kmsKeyId: 'kmsKeyId',
  supportedOsVersions: ['supportedOsVersions'],
  tags: {
    tagsKey: 'tags',
  },
  uri: 'uri',
});
```

## Initializer

```ts
new CfnComponent(scope: Construct, id: string, props: CfnComponentProps)
```

## Construct Props

- `changeDescription`: string — 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.

- `data`: string — 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.

- `description`: string — Describes the contents of the component.

- `kmsKeyId`: string — 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* .

- `name`: string (required) — The name of the component.

- `platform`: string (required) — The operating system platform of the component.

- `supportedOsVersions`: string[] — 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.

- `tags`: { [key: string]: string } — The tags that apply to the component.

- `uri`: string — The `uri` of a YAML component document file.

  This must be an S3 URL ( `s3://bucket/key` ), and the requester 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.

  Alternatively, you can specify the YAML document inline, using the component `data` property. You cannot specify both properties.

- `version`: string (required) — 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, with an upper limit of 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.

## Properties

- `attrArn`: string — Returns the Amazon Resource Name (ARN) of the component.

  The following pattern is applied: `^arn:aws[^:]*:imagebuilder:[^:]+:(?:\d{12}|aws):(?:image-recipe|infrastructure-configuration|distribution-configuration|component|image|image-pipeline)/[a-z0-9-_]+(?:/(?:(?:x|\d+)\.(?:x|\d+)\.(?:x|\d+))(?:/\d+)?)?$` .

- `attrEncrypted`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) — Returns the encryption status of the component.

  For example `true` or `false` .

- `attrLatestVersion`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) — The latest version references of the component.

- `attrLatestVersionArn`: string — The latest version Amazon Resource Name (ARN) of the Image Builder resource.

- `attrLatestVersionMajor`: string — The latest version Amazon Resource Name (ARN) with the same `major` version of the Image Builder resource.

- `attrLatestVersionMinor`: string — The latest version Amazon Resource Name (ARN) with the same `minor` version of the Image Builder resource.

- `attrLatestVersionPatch`: string — The latest version Amazon Resource Name (ARN) with the same `patch` version of the Image Builder resource.

- `attrName`: string — Returns the name of the component.

- `attrType`: string — Image Builder determines the component type based on the phases that are defined in the component document.

  If there is only one phase, and its name is "test", then the type is `TEST` . For all other components, the type is `BUILD` .

- `CFN_RESOURCE_TYPE_NAME`: string (static) — The CloudFormation resource type name for this resource class.

- `cfnOptions`: [ICfnResourceOptions](/cdk/api/v2/docs/aws-cdk-lib.ICfnResourceOptions.html) — Options for this resource, such as condition, update policy etc.

- `cfnResourceType`: string — AWS resource type.

- `changeDescription`: string — The change description of the component.

- `componentRef`: [ComponentReference](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_imagebuilder.ComponentReference.html) — A reference to a Component resource.

- `creationStack`: string[]

- `data`: string — Component `data` contains inline YAML document content for the component.

- `description`: string — Describes the contents of the component.

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html)

- `kmsKeyId`: string — The Amazon Resource Name (ARN) that uniquely identifies the KMS key used to encrypt this component.

- `logicalId`: string — 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)`.

- `name`: string — The name of the component.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) — The tree node.

- `platform`: string — The operating system platform of the component.

- `ref`: string — Return a string that will be resolved to a CloudFormation `{ Ref }` for this element.

  If, by any chance, the intrinsic reference of a resource is not a string, you could
  coerce it to an IResolvable through `Lazy.any({ produce: resource.ref })`.

- `stack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) — The stack in which this element is defined.

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

- `supportedOsVersions`: string[] — The operating system (OS) version supported by the component.

- `tags`: [TagManager](/cdk/api/v2/docs/aws-cdk-lib.TagManager.html) — Tag Manager which manages the tags for this resource.

- `tagsRaw`: { [key: string]: string } — The tags that apply to the component.

- `uri`: string — The `uri` of a YAML component document file.

- `version`: string — The semantic version of the component.

  This version follows the semantic version syntax.

## Methods

- `addDeletionOverride(path: string): void` — Syntactic sugar for `addOverride(path, undefined)`.

  **Parameters**

  - `path` — The path of the value to delete.

- `addDependency(target: CfnResource): void` — Use `addResourceDependency` instead.

  This method has been renamed to `addResourceDependency` to more clearly
  set it apart from `construct.node.addDependency`. See the documentation
  of that function for more details.

- `addDependsOn(target: CfnResource): void` — Use `addResourceDependency` instead.

  This can be used for resources across stacks (or nested stack) boundaries
  and the dependency will automatically be transferred to the relevant scope.

  This method has been renamed to `addResourceDependency`, which makes it
  more clear that this method operates at a different level from the
  construct-level `construct.node.addDependency()` mechanism.

- `addMetadata(key: string, value: any): void` — Add a value to the CloudFormation Resource Metadata.

- `addOverride(path: string, value: any): void` — 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,
  ```typescript
  cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
  cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');
  ```
  would add the overrides
  ```json
  "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` — - The path of the property, you can use dot notation to override values in complex types.
  - `value` — - The value.

- `addPropertyDeletionOverride(propertyPath: string): void` — Adds an override that deletes the value of a property from the resource definition.

  **Parameters**

  - `propertyPath` — The path to the property.

- `addPropertyOverride(propertyPath: string, value: any): void` — Adds an override to a resource property.

  Syntactic sugar for `addOverride("Properties.<...>", value)`.

  **Parameters**

  - `propertyPath` — The path of the property.
  - `value` — The value.

- `addResourceDependency(target: CfnResource, reason?: string): void` — 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.

  This method only adds dependencies between L1 resources. If you are
  looking for a generic construct-to-construct dependency mechanism that works
  for all constructs including L2s, use `construct.node.addDependency` instead.

- `applyCrossStackReferenceStrength(strength: ReferenceStrength): void` — Sets the cross-stack reference strength for this resource.

  When set, any cross-stack reference to this resource will use the specified
  strength instead of the global default from the consuming stack's context.

  **Parameters**

  - `strength` — - The reference strength to use for this resource.

- `applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void` — 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:

- `arnForComponent(resource: IComponentRef): string` (static)

- `cfnPropertyName(cdkPropertyName: string): string`

- `getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference` — 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**

  - `attributeName` — The name of the attribute.

- `getMetadata(key: string): any` — Retrieve a value value from the CloudFormation Resource Metadata.

- `inspect(inspector: TreeInspector): void` — Examines the CloudFormation resource and discloses attributes.

  **Parameters**

  - `inspector` — tree inspector to collect and process attributes.

- `isCfnComponent(x: any): boolean` (static) — Checks whether the given object is a CfnComponent.

- `isCfnElement(x: any): boolean` (static) — 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.

  **Returns:** The construct as a stack element or undefined if it is not a stack element.

- `isCfnResource(x: any): boolean` (static) — Check whether the given object is a CfnResource.

- `isConstruct(x: any): boolean` (static) — 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 object.

  **Returns:** true if `x` is an object created from a class which extends `Construct`.

- `obtainDependencies(): Stack | CfnResource[]` — Retrieves an array of resources and stacks this resource depends on.

  For resources depended on directly, returns the `CfnResource` object. For
  dependencies on other stacks, returns the `Stack` object. The order of the
  array is not guaranteed.

- `overrideLogicalId(newLogicalId: string): void` — Overrides the auto-generated logical ID with a specific ID.

  **Parameters**

  - `newLogicalId` — The new logical ID to use for this stack element.

- `removeDependency(target: CfnResource): void` — Use `removeResourceDependency` instead

  This can be used for resources across stacks (including nested stacks)
  and the dependency will automatically be removed from the relevant scope.

- `removeResourceDependency(target: CfnResource): void` — Indicates that this resource no longer depends on another resource.

  This can be used for resources across stacks (including nested stacks)
  and the dependency will automatically be removed from the relevant scope.

- `replaceDependency(target: CfnResource, newTarget: CfnResource): void` — Replaces one dependency with another.

  **Parameters**

  - `target` — The dependency to replace.
  - `newTarget` — The new dependency to add.

- `toString(): string` — Returns a string representation of this construct.

  **Returns:** a string representation of this resource

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.
  Use multiple `with()` calls if subsequent mixins should apply to added
  constructs.
