Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :type (required, String) —

    The layer type. A stack cannot have more than one built-in layer of the same type. It can have any number of custom layers. Built-in layers are not available in Chef 12 stacks.

  • :name (required, String) —

    The layer name, which is used by the console. Layer names can be a maximum of 32 characters.

  • :shortname (required, String) —

    For custom layers only, use this parameter to specify the layer's short name, which is used internally by OpsWorks Stacks and by Chef recipes. The short name is also used as the name for the directory where your app files are installed. It can have a maximum of 32 characters, which are limited to the alphanumeric characters, '-', '_', and '.'.

    Built-in layer short names are defined by OpsWorks Stacks. For more information, see the Layer Reference.

  • :attributes (Hash<String,String>) —

    One or more user-defined key-value pairs to be added to the stack attributes.

    To create a cluster layer, set the EcsClusterArn attribute to the cluster's ARN.

  • :cloud_watch_logs_configuration (Types::CloudWatchLogsConfiguration) —

    Specifies CloudWatch Logs configuration options for the layer. For more information, see CloudWatchLogsLogStream.

  • :custom_instance_profile_arn (String) —

    The ARN of an IAM profile to be used for the layer's EC2 instances. For more information about IAM ARNs, see Using Identifiers.

  • :custom_json (String) —

    A JSON-formatted string containing custom stack configuration and deployment attributes to be installed on the layer's instances. For more information, see Using Custom JSON. This feature is supported as of version 1.7.42 of the CLI.

  • :custom_security_group_ids (Array<String>) —

    An array containing the layer custom security group IDs.

  • :packages (Array<String>) —

    An array of Package objects that describes the layer packages.

  • :volume_configurations (Array<Types::VolumeConfiguration>) —

    A VolumeConfigurations object that describes the layer's Amazon EBS volumes.

  • :enable_auto_healing (Boolean) —

    Whether to disable auto healing for the layer.

  • :auto_assign_elastic_ips (Boolean) —

    Whether to automatically assign an Elastic IP address to the layer's instances. For more information, see How to Edit a Layer.

  • :auto_assign_public_ips (Boolean) —

    For stacks that are running in a VPC, whether to automatically assign a public IP address to the layer's instances. For more information, see How to Edit a Layer.

  • :custom_recipes (Types::Recipes) —

    A LayerCustomRecipes object that specifies the layer custom recipes.

  • :install_updates_on_boot (Boolean) —

    Whether to install operating system and package updates when the instance boots. The default value is true. To control when updates are installed, set this value to false. You must then update your instances manually by using CreateDeployment to run the update_dependencies stack command or by manually running yum (Amazon Linux) or apt-get (Ubuntu) on the instances.

    To ensure that your instances have the latest security updates, we strongly recommend using the default value of true.

  • :use_ebs_optimized_instances (Boolean) —

    Whether to use Amazon EBS-optimized instances.

  • :lifecycle_event_configuration (Types::LifecycleEventConfiguration) —

    A LifeCycleEventConfiguration object that you can use to configure the Shutdown event to specify an execution timeout and enable or disable Elastic Load Balancer connection draining.

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::OpsWorks::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

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

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

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

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

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

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

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

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

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

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

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

  • (NotImplementedError) —

    Raised when the resource does not
