Flows

A flow is a set of tasks written in YAML. It runs when you start it or when a trigger fires.

Flows

The workflow worker is off by default

The platform only queues executions until the worker is enabled with EGRET_WORKFLOW__WORKER_ENABLED=true (and EGRET_WORKFLOW__SCHEDULER_ENABLED=true for triggers). With the worker off, Run succeeds but the execution waits in Running until a worker starts. Only the Triggers page warns about this today.

Create a flow​

Press New flow. The editor opens with a starter flow and a Docs panel generated from the flow schema.

The flow editor

id: hello
namespace: company.team
tasks:
  - id: hello
    type: io.kestra.plugin.core.log.Log
    message: Hello from egret

The flow's namespace and id come from its namespace: and id: keys. Save creates it. Saving a flow that already exists is rejected with a flow already exists at company.team/hello in this workspace.

A flow

A flow has Edit, Revisions, Executions and Triggers tabs. Save stores the draft, Create version publishes a version and Run starts an execution of the saved draft. Flows with inputs ask for them before running.
