/AWS1/CL_OWX=>CREATELAYER()

About CreateLayer

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.

IMPORTING

Required arguments:

IV_STACKID TYPE /AWS1/OWXSTRING /AWS1/OWXSTRING

The layer stack ID.

IV_TYPE TYPE /AWS1/OWXLAYERTYPE /AWS1/OWXLAYERTYPE

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

Whether to disable auto healing for the layer.

IV_AUTOASSIGNELASTICIPS TYPE /AWS1/OWXBOOLEAN /AWS1/OWXBOOLEAN

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

IV_AUTOASSIGNPUBLICIPS TYPE /AWS1/OWXBOOLEAN /AWS1/OWXBOOLEAN

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.

A LayerCustomRecipes object that specifies the layer custom recipes.

IV_INSTALLUPDATESONBOOT TYPE /AWS1/OWXBOOLEAN /AWS1/OWXBOOLEAN

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.
