Forward same request to a service in every namespaces

[bcouetil]

Hello, thank you for maintaining this tool 😊

My use case is forwarding the request to a service in every namespaces.

I guess I could create a single WebhookRelayForward with multiple outputs like this :

      outputs:
        - name: business-backend-ns1
          destination: http://business-backend.ns1.svc.cluster.local
          internal: true
          lockPath: false
        - name: business-backend-ns2
          destination: http://business-backend.ns2.svc.cluster.local
          internal: true
          lockPath: false

But it means being aware of every namespaces at once, and mines are dynamic (these are ephemeral environments which all needs the requests).

Do I have another solution ? would it work if I created the same object in each namespace ; would it merge the redirection to do all, or would it be overriden each time by the latest ?

Thanks in advance for any input 🙏

Hi!
Have you thought about just running the agent itself without the operator on each namespace next to your business-backend deployment? Then the URL is the same for each agent and they all subscribe to the same bucket with the same single output :)

Oh great, how do I run the agent without the operator ? should I template the helm chart and cherry pick some objects ?

Here's an example of deployment yaml https://docs.webhookrelay.com/installation-options/containerized/kubernetes-installation#option-3-separate-deployment.

It might make sense to create a helm chart too but it's a single container 😃

I understand, simpler is better, no need for Hell Helm chart for that.

My first reaction was "man, where are the other variables ?", but indeed, if the target is the same service in each namespace, no need for more !

Thank you very much, I'll try that 🙏

It works like a charm.

Cherry on the cake, only needed namespaces have the webhook, and each one can subscribe autonomously.
