48.3. Usage
This section describes how you can use the replace-field-action.
48.3.1. Knative Action
You can use the replace-field-action Kamelet as an intermediate step in a Knative binding.
replace-field-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: replace-field-action-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: timer-source
properties:
message: "Hello"
steps:
