Connector essentials

Jan 11, 2018

Connectors in Citrix App Layering appliance, also known as Enterprise Layer Manager (ELM), are the interfaces to environments where you create layers and publish Layered Images. You create one or more Connector Configurations for each platform where you intend to package layers or publish Layered Images.

A Connector Configuration is a stored set of values for connecting to a storage location in your environment. A configuration includes authentication credentials, a storage location, and any other information to interface with the environment where you create layers or publishing images. You can create multiple Connector Configurations, each configured to access a unique location in your environment.

Connector Configurations requirements

You need Connector Configurations for importing an operating system to create an OS Layer. The Connector Configuration gives the appliance access to the location of the operating system image that you use when you create an OS Layer.

The appliance requires a Connector Configuration for the location in your environment where you package the layer when you:

  • Create an App Layer.
  • Update an App Layer.
  • Add a version to an OS Layer.

 You can create as many configurations as you need. For example, when you have more than one storage location in the environment.

Connector Configurations for publishing Layered Images

Publishing Layered Images requires different Connector Configurations than the configurations you use for creating Layers; for example, when publishing Layered Images to various storage locations near the location where you serve users. You can publish Layered Images to more than one storage location in the same environment, each requiring a different Connector Configuration. Each location is likely to require different credentials.

How and when to add a Connector Configuration

If you are using the appliance for the first time, add one or more Connector Configurations when you add layers and publish Layered Images. The following wizards, located in the management console, include a page for selecting and creating Connector Configurations:

  • Creating layers wizard
  • Adding versions wizard
  • Publishing Layered Images wizard
