Runnable Tasks

Data processing tasks handled by the workers.

Runnable tasks handle data processing, such as file system operations, API calls, and database queries. They can be compute-intensive and are executed by workers.

Each task requires an identifier (id) and a type, defined by its Java Fully Qualified Class Name (FQCN).

Tasks include properties specific to their type. Refer to each task’s documentation for a full list of available properties.

Most tasks are runnable, except for Flowable tasks, which control orchestration logic.

By default, Kestra includes only a few runnable tasks. Many more are available as plugins, and the default Docker image comes preloaded with several of them.

Example

The following example shows two runnable tasks: one that makes an HTTP request and another that logs its output.

id: runnable_http
namespace: company.team

tasks:
  - id: make_request
    type: io.kestra.plugin.core.http.Request
    uri: https://kestra.io/api/mock
    method: GET
    contentType: application/json

  - id: print_status
    type: io.kestra.plugin.core.log.Log
    message: "{{ outputs.make_request.body }}"
