I got the following YAML from: https://raw.githubusercontent.com/argoproj/argo-events/stable/examples/sensors/webhook.yaml

and saved it at a.yaml

However, when I do

kubectl apply -f a.yaml

I get:

error: unable to recognize "a.yaml": no matches for kind "Sensor" in version "argoproj.io/v1alpha1"

Not sure why Sensor is not valid "Kind"

CodePudding user response：

The Kubernetes api can be extended. Kubernetes by default does not know this kind.

You have to install it.

Check this with your System-admin on a Production-Side.

CodePudding user response：

There are two requirements for this to work:

1. You need a cluster with Alpha Features Enabled: https://cloud.google.com/kubernetes-engine/docs/how-to/creating-an-alpha-cluster

AND

2. You need argo events installed

kubectl create ns argo-events
kubectl apply -f https://raw.githubusercontent.com/argoproj/argo-events/stable/manifests/namespace-install.yaml

Then you can install a webhook Sensor.
