Flow

type: "io.kestra.core.models.triggers.types.Flow"

Kestra is able to trigger flow after another one. This allows chaining flow without need to update the base flows.
With that, you can break responsibility between different flow to different teams.

WARNING

If you don't provide any conditions, the flow will be triggered for EVERY execution of EVERY flow on your instance.

Examples

This flow will be triggered after each successfully execution of flow io.kestra.tests.trigger-flow and forward the uri of my-task taskId outputs.

id: "flow"
type: "io.kestra.core.models.triggers.types.Flow"
id: trigger-flow-listener
namespace: io.kestra.tests
revision: 1

inputs:
  - name: from-parent
    type: STRING

tasks:
  - id: only-no-input
    type: io.kestra.core.tasks.debugs.Return
    format: "v1: {{trigger.executionId}}"

triggers:
  - id: listen-flow
    type: io.kestra.core.models.triggers.types.Flow
    inputs:
      from-parent: '{{ outputs.myTask.uri }}'
    conditions:
      - type: io.kestra.core.models.conditions.types.ExecutionFlowCondition
        namespace: io.kestra.tests
        flowId: trigger-flow
      - type: io.kestra.core.models.conditions.types.ExecutionStatusCondition
        in:

Properties

inputs

• Type: object
• Dynamic: ❌
• Required: ❌

Fill input of this flow based on output of current flow, allowing to pass data or file on the triggered flow

WARNING

If you provide invalid input, the flow will not be created! Since there is no task started, you can't log any reason visible on the execution ui.
So you will need to go to Logs tabs on the ui to understand the error
