Managing Inputs, Outputs and Capabilities

Cloudify Composer enables you to add inputs and outputs to the Blueprint under the Inputs & Outputs node.

Inputs and Outputs

Inputs are parameters that are injected into a blueprint when a deployment is created. They enable you to add data that might not have been available when a blueprint was created. They also enable you to create different “flavors” of a blueprint.

Outputs provide a method to expose global aspects of a blueprint’s deployment. For example, the endpoint of a server, or runtime or static information about a specific resource.

Inputs and outputs can be referenced from other parts of the topology, using the get-input intrinsic function.

Adding an Input

  1. On the Inputs node, enter a name and description for your input.
  2. (Optional) Specify input display name and default value. Further optional input properties are available after expanding the input section. After clicking the dropdown icon on the left side of the section it is possible to provide input description as well as enable hidden and required flags.
  3. (Optional) Change the default string data type of the input.
  4. Click the Plus (+) icon to add the input to the list.
