ly event

ly event

Publish a CloudEvent to a service:

build/ly event publish --id order-123 --data '{"order":123}' services/hello-edge

Option	Default	Purpose
--id	generated	Event ID, reused across retries.
--data	{}	JSON event data.
--path	/events	Request path.
--url	deployed service URL	Override the destination.
--context	current-context	Kubeconfig context for URL discovery.
--insecure	false	Disable TLS certificate verification.

With events: in lampyr.yaml, publishing uses its retry and local dead-letter settings. Without it, Handler Applications in every runtime receive one direct attempt with no retry or dead-letter record. Standalone Applications require events: to publish.

TLS verification is enabled unless --insecure is set or an automatically discovered destination uses localhost or *.localhost.

Without --url, publishing uses the deployed Knative Service URL. A cluster-local service is not assumed reachable from your machine: pass --url with a reachable endpoint, such as a port-forward URL. Explicit URLs retain the same verification and retry behavior.

Provider event sources

Provider sources require deployed events: policy. For Azure, install with --eventing and define a source in the provider workspace:

eventSources:
  blob-created:
    storageAccount: lyevents123
    container: events

Initialization stores these definitions in event-sources.json.

build/ly event source create --provider azure --name blob-created services/hello-edge
build/ly event source status --provider azure --name blob-created services/hello-edge
build/ly event source delete --provider azure --name blob-created services/hello-edge

Option	Default	Purpose
--name	required	Source definition and Trigger name.
--provider	required	Provider that owns the source.
--context	current-context	Kubeconfig context.
--namespace	default	Service and source namespace.

Azure accepts storageAccount, resourceGroup, container, eventTypes, or an absolute sourceResourceId as source settings, not CLI options. The default event type is Microsoft.Storage.BlobCreated.

Sources deliver to /events/knative; the sample returns the required HTTP 204. Deleting a source removes its Source and Trigger, not the shared Broker.
