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 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 only accepts Lambda functions that use the following runtimes:
Python 2.7 – python2.7
Python 3.7 – python3.7
Python 3.8 – python3.8
Java 8 – java8
Node.js 10 – nodejs10.x
Node.js 12 – nodejs12.x
To create a component from a Lambda function, specify lambdaFunction when you call this operation.

Creates a continuous deployment for a target, which is a AWS IoT Greengrass core device or group of core devices. When you add a new core device to a group of core devices that has a deployment, AWS IoT Greengrass deploys that group's deployment to the new device.
You can define one deployment for each target. When you create a new deployment for a target that has an existing deployment, you replace the previous deployment. AWS IoT Greengrass applies the new deployment to the target devices.
Every deployment has a revision number that indicates how many deployment revisions you define for a target. Use this operation to create a new revision of an existing deployment. This operation returns the revision number of the new deployment when you create it.
For more information, see the Create deployments in the AWS IoT Greengrass V2 Developer Guide .

For more information, see Update component configurations in the AWS IoT Greengrass V2 Developer Guide .
merge (string) --
A serialized JSON string that contains the configuration object to merge to target devices. The core device merges this configuration with the component's existing configuration. If this is the first time a component deploys on a device, the core device merges this configuration with the component's default configuration. This means that the core device keeps it's existing configuration for keys and values that you don't specify in this object. For more information, see Merge configuration updates in the AWS IoT Greengrass V2 Developer Guide .
reset (list) --
The list of configuration nodes to reset to default values on target devices. Use JSON pointers to specify each node to reset. JSON pointers start with a forward slash (/ ) and use forward slashes to separate the key for each level in the object. For more information, see the JSON pointer specification and Reset configuration updates in the AWS IoT Greengrass V2 Developer Guide .
(string) --
runWith (dict) --
The system user and group that the AWS IoT Greengrass Core software uses to run component processes on the core device.

The minimum percentage of failureType failures that occur before the job can cancel.
This parameter supports up to two digits after the decimal (for example, you can specify 10.9 or 10.99 , but not 10.999 ).
minNumberOfExecutedThings (integer) -- [REQUIRED]
The minimum number of things that receive the configuration before the job can cancel.
timeoutConfig (dict) --
The timeout configuration for the job. This configuration defines the amount of time each device has to complete the job.
inProgressTimeoutInMinutes (integer) --
The amount of time, in minutes, that devices have to complete the job. The timer starts when the job status is set to IN_PROGRESS . If the job status doesn't change to a terminal state before the time expires, then the job status is set to TIMED_OUT .

Default: 60
action (string) --
Whether or not to notify components and wait for components to become safe to update. Choose from the following options:
NOTIFY_COMPONENTS – The deployment notifies each component before it stops and updates that component. Components can use the SubscribeToComponentUpdates IPC operation to receive these notifications. Then, components can respond with the DeferComponentUpdate IPC operation. For more information, see the Create deployments in the AWS IoT Greengrass V2 Developer Guide .
SKIP_NOTIFY_COMPONENTS – The deployment doesn't notify components or wait for them to be safe to update.
Default: NOTIFY_COMPONENTS

Retrieves a list of components that meet the component, version, and platform requirements of a deployment. AWS IoT Greengrass core devices call this operation when they receive a deployment to identify the components to install.
This operation identifies components that meet all dependency requirements for a deployment. If the requirements conflict, then this operation returns an error and the deployment fails. For example, this occurs if component A requires version >2.0.0 and component B requires version <2.0.0 of a component dependency.
When you specify the component candidates to resolve, AWS IoT Greengrass compares each component's digest from the core device with the component's digest in the AWS Cloud. If the digests don't match, then AWS IoT Greengrass specifies to use the version from the AWS Cloud.
Warning
To use this operation, you must use the data plane API endpoint and authenticate with an AWS IoT device certificate. For more information, see AWS IoT Greengrass endpoints and quotas .
