Get metadata Example
This is a "hello-world" with a Metadata example of LittleHorse using GoLang.
What's Going On
The file workflow.go has two functions defined:
GetInfo
, which is a Task Function (task accepts a struct as an input variable; only pointers to struct are supported).MyWorkflowGet
, which is the Workflow Function.
Deploy the Task Worker
Before we can create the WfSpec
, we need to register the TaskDef
. The easiest way to do that is to run the task worker:
go run ./taskmetadata/worker
Leave that process running.
Register the WfSpec
Next, in another terminal, run:
go run ./taskmetadata/deploy
That will create the WfSpec
. You can verify that via:
lhctl get wfSpec my-workflow
Run a WfRun
To run a WfRun
, you can use lhctl
.
lhctl run my-workflow input '{"foo": 1, "art":{"id":1,"title": "bugia", "content": "lol"}}'
It will print out an ID. You can view the status of that WfRun
via:
lhctl get wfRun <the id from the previous step>
