Class: Aws::IoTThingsGraph::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for AWS IoT Things Graph. To construct a client, you need to configure a :region and :credentials.

iotthingsgraph = Aws::IoTThingsGraph::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::IoTThingsGraph::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details

#associate_entity_to_thing(options = {}) ⇒ Struct

Associates a device with a concrete thing that is in the user's registry.

A thing can be associated with only one device at a time. If you associate a thing with a new device id, its previous association will be removed.

Examples:

Request syntax with placeholder values


resp = client.associate_entity_to_thing({
  thing_name: "ThingName", # required
  entity_id: "Urn", # required
  namespace_version: 1,
})

Options Hash (options):

  • :thing_name (required, String)

    The name of the thing to which the entity is to be associated.

  • :entity_id (required, String)

    The ID of the device to be associated with the thing.

    The ID should be in the following format.

    urn:tdm:REGION/ACCOUNT ID/default:device:DEVICENAME

  • :namespace_version (Integer)

    The version of the user\'s namespace. Defaults to the latest version of the user\'s namespace.

Returns:

  • (Struct)

    Returns an empty response.

#create_flow_template(options = {}) ⇒ Types::CreateFlowTemplateResponse

Creates a workflow template. Workflows can be created only in the user's namespace. (The public namespace contains only entities.) The workflow can contain only entities in the specified namespace. The workflow is validated against the entities in the latest version of the user's namespace unless another namespace version is specified in the request.

Examples:

Request syntax with placeholder values


resp = client.create_flow_template({
  definition: { # required
    language: "GRAPHQL", # required, accepts GRAPHQL
    text: "DefinitionText", # required
  },
  compatible_namespace_version: 1,
})

Response structure


resp.summary.id #=> String
resp.summary.arn #=> String
resp.summary.revision_number #=> Integer
resp.summary.created_at #=> Time

Options Hash (options):

  • :definition (required, Types::DefinitionDocument)

    The workflow DefinitionDocument.

  • :compatible_namespace_version (Integer)

    The namespace version in which the workflow is to be created.

    If no value is specified, the latest version is used by default.

Returns:

#create_system_instance(options = {}) ⇒ Types::CreateSystemInstanceResponse

Creates a system instance.

This action validates the system instance, prepares the deployment-related resources. For Greengrass deployments, it updates the Greengrass group that is specified by the greengrassGroupName parameter. It also adds a file to the S3 bucket specified by the s3BucketName parameter. You need to call DeploySystemInstance after running this action.

For Greengrass deployments, since this action modifies and adds resources to a Greengrass group and an S3 bucket on the caller's behalf, the calling identity must have write permissions to both the specified Greengrass group and S3 bucket. Otherwise, the call will fail with an authorization error.

For cloud deployments, this action requires a flowActionsRoleArn value. This is an IAM role that has permissions to access AWS services, such as AWS Lambda and AWS IoT, that the flow uses when it executes.

If the definition document doesn't specify a version of the user's namespace, the latest version will be used by default.

Examples:

Request syntax with placeholder values


resp = client.create_system_instance({
  tags: [
    {
      key: "TagKey", # required
      value: "TagValue", # required

#upload_entity_definitions(options = {}) ⇒ Types::UploadEntityDefinitionsResponse

Asynchronously uploads one or more entity definitions to the user's namespace. The document parameter is required if syncWithPublicNamespace and deleteExistingEntites are false. If the syncWithPublicNamespace parameter is set to true, the user's namespace will synchronize with the latest version of the public namespace. If deprecateExistingEntities is set to true, all entities in the latest version will be deleted before the new DefinitionDocument is uploaded.

When a user uploads entity definitions for the first time, the service creates a new namespace for the user. The new namespace tracks the public namespace. Currently users can have only one namespace. The namespace version increments whenever a user uploads entity definitions that are backwards-incompatible and whenever a user sets the syncWithPublicNamespace parameter or the deprecateExistingEntities parameter to true.

The IDs for all of the entities should be in URN format. Each entity must be in the user's namespace. Users can't create entities in the public namespace, but entity definitions can refer to entities in the public namespace.

Valid entities are Device, DeviceModel, Service, Capability, State, Action, Event, Property, Mapping, Enum.

Examples:

Request syntax with placeholder values


resp = client.upload_entity_definitions({
  document: {
    language: "GRAPHQL", # required, accepts GRAPHQL

  • :document (Types::DefinitionDocument)

    The DefinitionDocument that defines the updated entities.

  • :sync_with_public_namespace (Boolean)

    A Boolean that specifies whether to synchronize with the latest version of the public namespace. If set to true, the upload will create a new namespace version.

  • :deprecate_existing_entities (Boolean)

    A Boolean that specifies whether to deprecate all entities in the latest version before uploading the new DefinitionDocument. If set to true, the upload will create a new namespace version.

Returns:

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(...) do |w|

  # disable max attempts
  w.max_attempts = nil

  # poll for 1 hour, instead of a number of attempts
  w.before_wait do |attempts, response|
    throw :failure if Time.now - started_at > 3600
  end

end

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.

#waiter_namesArray<Symbol>

Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:

Waiter NameClient MethodDefault Delay:Default Max Attempts:

Returns:

  • (Array<Symbol>)

    the list of supported waiters.
