​Runnable ​Tasks in ​Kestra – ​Execute ​Workloads

Data processing tasks handled by the workers.

Execute work with runnable tasks

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 }}"
