Inputs

You are looking at documentation for an older release. Not what you want? Go to the current release documentation.

inputs are parameters that are injected into a blueprint when a deployment is created. These parameters can be referenced by using the get_input intrinsic function.

Inputs are useful when there is a need to inject parameters in the blueprint that were unknown when the blueprint was created, and they can be used for distinction between different deployments of the same blueprint.

Note

Beginning with definitions version cloudify_dsl_1_3, you can also import inputs multiple times.

Also note that you can pass multiple -i flags in the CLI, to pass multiple input structures or to pass wildcard-based paths to input files (e.g. ... -i *.yaml) and directories containing input files (e.g. ... -i my_inputs_file_dir/)

Declaration

  
inputs:

  input1:
    ...
  input2:
    ...

Schema

Keyname	Required	Type	Description
description	no	string	An optional description for the input.
type	no	string	The required data type of the input. Not specifying a data type means the type can be anything. Valid types: string, integer, boolean
default	no	<any>	An optional default value for the input.

Example

  

inputs:

  image_name:
    description: The image name of the server
    type: string
    default: "Ubuntu 12.04"

node_templates:

  vm:
    type: cloudify.openstack.nodes.Server
    properties:
      server:
        image_name: { get_input: image_name }

get_input is a special function which enables you to use inputs throughout the blueprint. For more information see intrinsic_functions.
