Core Plugins and tasks ExecutionOutputs

Core Plugins and tasks ExecutionOutputs
Certified
Condition based on the outputs of an upstream execution.

Renders the provided boolean expression against the upstream execution outputs exposed under trigger.outputs.

If the execution exposes no outputs the condition is false and the expression is skipped. A rendered result of blank, space-only, or literal false is treated as false.

yaml
type: io.kestra.plugin.core.condition.ExecutionOutputs

Examples

The upstream flow_a must explicitly define its outputs to be used in the ExecutionOutputs condition.

id: flow_a
namespace: company.team

inputs: 
  - id: user_value
    type: STRING
    defaults: hello

tasks: 
  - id: hello
    type: io.kestra.plugin.core.debug.Return
    format: "{{ inputs.user_value }}"

outputs: 
  - id: flow_a_output
    type: STRING
    value: "{{ outputs.hello.value }}"

The flow_condition_executionoutputs will run whenever flow_a finishes successfully and returns an output matching the value 'hello':

yaml
id: flow_condition_executionoutputs
namespace: company.team

tasks:
  - id: upstream_outputs
    type: io.kestra.plugin.core.log.Log
    message: hello from a downstream flow

triggers:
  - id: condition_on_flow_execution_outputs
    type: io.kestra.plugin.core.trigger.Flow
    states:
      - SUCCESS
    conditions:
      - type: io.kestra.plugin.core.condition.ExecutionOutputs
        expression: "{{ trigger.outputs.flow_a_output == 'hello' }}"
