Outputs

When deployed, a service template can expose specific outputs of that deployment - for instance, an ip address of a server or any other runtime or static information of a specific resource.

Declaration

outputs:
  output1:
    ...
  output2:
    ...

Definition

Keyname	Required	Type	Description
description	no	string	An optional description for the output.
value	yes	<any>	The output value. May be anything from a simple value (e.g. port) to a complex value (e.g. hash with values). Output values can contain hard-coded values, inputs, properties and attributes.

Example

topology_template:
   node_templates:
     webserver_vm:
       type: tosca.nodes.Compute
     webserver:
       type: tosca.nodes.WebServer
       properties:
           port: 8080

   outputs:
       webapp_endpoint:
           description: ip and port of the web application
           value:
               ip: { get_attribute: [webserver_vm, ip] }
               port: { get_property: [webserver, port] }

Job Status

Outputs are printed in the console after a job has completed as part of the job summary and recorded in the ensemble.yaml’s status section:

status:
  outputs:
    webapp_endpoint:
      ip: 127.0.0.1
      port: 8080
