Subflow

type: "io.kestra.plugin.core.flow.Subflow"

Create a subflow execution. Subflows offer a modular way to reuse workflow logic by calling other flows just like calling a function in a programming language.

Examples

Run a subflow with custom inputs.

id: "subflow"
type: "io.kestra.plugin.core.flow.Subflow"
id: running_subflow
namespace: company.team

tasks:
  - id: call_subflow
    type: io.kestra.plugin.core.flow.Subflow
    namespace: company.team
    flowId: subflow
    inputs:
      user: "Rick Astley"
      favorite_song: "Never Gonna Give You Up"
    wait: true
    transmitFailed: true
