Core Plugins and tasks OutputValues

Core Plugins and tasks OutputValues

Certified

Emit custom values from a task.

Renders the provided map and returns it under outputs.<taskId>.values. Accepts strings, numbers, arrays, or JSON objects; templated entries are rendered with the current context.

Use to surface intermediate data for downstream tasks or inspection in the Outputs tab.

yaml
type: io.kestra.plugin.core.output.OutputValues
yaml
id: outputs_flow
namespace: company.team

tasks:
  - id: output_values
    type: io.kestra.plugin.core.output.OutputValues
    values:
      taskrun_data: "{{ task.id }} > {{ taskrun.startDate }}"
      execution_data: "{{ flow.id }} > {{ execution.startDate }}"
      number_value: 42
      array_value: ["{{ task.id }}", "{{ flow.id }}", "static value"]
      nested_object:
        key1: "value1"
        key2: "{{ execution.id }}"

  - id: log_values
    type: io.kestra.plugin.core.log.Log
    message: |
      Got the following outputs from the previous task:
      {{ outputs.output_values.values.taskrun_data }}
      {{ outputs.output_values.values.execution_data }}
      {{ outputs.output_values.values.number_value }}
      {{ outputs.output_values.values.array_value[1] }}
      {{ outputs.output_values.values.nested_object.key2 }}
Properties

Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

Definitions

Possible Values
IGNOREFAILWARN

Asset failure behavior

Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.

enableAutobooleanstring

Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.

inputsarray

The assets consumed as inputs.
