Create Layer

opsworks_create_layer

R Documentation

Creates a layer¶

Description¶

Creates a layer. For more information, see How to Create a Layer.

You should use CreateLayer for noncustom layer types such as PHP App Server only if the stack does not have an existing layer of that type. A stack can have at most one instance of each noncustom layer; if you attempt to create a second instance, CreateLayer fails. A stack can have an arbitrary number of custom layers, so you can call CreateLayer as many times as you like for that layer type.

Required Permissions: To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see Managing User Permissions.

Usage¶

opsworks_create_layer(StackId, Type, Name, Shortname, Attributes,
  CloudWatchLogsConfiguration, CustomInstanceProfileArn, CustomJson,
  CustomSecurityGroupIds, Packages, VolumeConfigurations,
  EnableAutoHealing, AutoAssignElasticIps, AutoAssignPublicIps,
  CustomRecipes, InstallUpdatesOnBoot, UseEbsOptimizedInstances,
  LifecycleEventConfiguration)

Arguments¶

StackId

[required] The layer stack ID.

Type

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

Shortname

[required] 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

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.

CloudWatchLogsConfiguration

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

CustomInstanceProfileArn

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

CustomJson

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.

CustomSecurityGroupIds

An array containing the layer custom security group IDs.

Packages

An array of Package objects that describes the layer packages.

VolumeConfigurations

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

EnableAutoHealing

Whether to disable auto healing for the layer.

AutoAssignElasticIps

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

AutoAssignPublicIps

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.

CustomRecipes

A LayerCustomRecipes object that specifies the layer custom recipes.

InstallUpdatesOnBoot

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 create_deployment 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.

UseEbsOptimizedInstances

Whether to use Amazon EBS-optimized instances.

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.

A list with the following syntax:

list(
  LayerId = "string"
