Event driven workflows

[douglas-smith-techlabs]

Hi - sorry, really basic getting started question here. But I can't seem to find it in the docs really. But if I want event driven workflows managed by Argo, I need to install argo workflows -and- argo events? When I install argo workflows, in the web interface I see events and sensors and the ability to create new events and sensors. But also, the docs say to install events in the namespace argo-events and the workflows in the namespace argo. If I am to install both argo events and argo workflows, should I install the argo events in the argo namespace for use with workflows?

You should install both of them in the same namespace, regardless of the specific name of the namespace. Make sure to use namespaced installation and specify --namespaced in your controllers.

You also need to install Event Bus on the Argo namespace in order for Argo Event to communicate with as well

Right, sure, so I need to download the argo-events manifest install yamls, and then edit them to change the namespace to argo from argo-events, and then use those to install? Or if I use -n argo in the kubectl will this over-ride the yaml namespace value?

You can use something like this

---
apiVersion: argoproj.io/v1alpha1
kind: EventBus
metadata:
  name: default
  namespace: argo
spec:
  nats:
    native:
      replicas: 3
      auth: token
