# AWS::GreengrassV2::ComponentVersion
<a name="aws-resource-greengrassv2-componentversion"></a>

Creates a component. Components are software that run on AWS IoT Greengrass core devices. After you develop and test a component on your core device, you can use this operation to upload your component to AWS IoT Greengrass. Then, you can deploy the component to other core devices.

You can use this operation to do the following:
+  **Create components from recipes** 

  Create a component from a recipe, which is a file that defines the component's metadata, parameters, dependencies, lifecycle, artifacts, and platform capability. For more information, see [AWS IoT Greengrass component recipe reference](https://docs.aws.amazon.com/greengrass/v2/developerguide/component-recipe-reference.html) in the *AWS IoT Greengrass V2 Developer Guide*.

  To create a component from a recipe, specify `inlineRecipe` when you call this operation.
+  **Create components from Lambda functions** 

  Create a component from an AWS Lambda function that runs on AWS IoT Greengrass. This creates a recipe and artifacts from the Lambda function's deployment package. You can use this operation to migrate Lambda functions from AWS IoT Greengrass V1 to AWS IoT Greengrass V2.

  This function accepts Lambda functions in all supported versions of Python, Node.js, and Java runtimes. AWS IoT Greengrass doesn't apply any additional restrictions on deprecated Lambda runtime versions.

  To create a component from a Lambda function, specify `lambdaFunction` when you call this operation.
