@vfarcic, tried to reply on your argo-events youtube video in the comment section, but somehow not able to. My comment kept getting deleted.

Hope you do not mind me commenting here. Attached is the gist on deploying sensor and eventsource in another namespace, which I cannot get it to work.

I added these commands, on top of your gist, to deploy in another namespace. https://gist.github.com/vaporpin/a80877ded979d9c92ee44515a74884b7

Sorry for the comments. YT tends to delete those that contain links.

I'm traveling right now and will not be back until the weekend. I hope that I'll be able to go through it sometime next week. Is that OK?

@vfarcic, definitely ok! in fact, thanks for helping out! enjoy your holiday!

Apologies victor for messaging here. Youtube doesnot allow me to add link.

To one of the queries which i posted in YT

below is the error log in ingress

2023/05/16 13:24:53 [error] 2318#2318: *134851 SSL_do_handshake() failed (SSL: error:0A00010B:SSL routines::wrong version number) while SSL handshaking to upstream, client: 152.37.90.132, server: argoeventsweb.simplifydevopstools.com, request: "POST /devops-tools HTTP/1.1", upstream: "https://10.224.0.82:8080/devops-tools", host: "argoeventsweb.simplifydevopstools.com"

I already answered in YouTube. We can continue here @sarsatis .

I'm trying to expose the webhook externally, however it doesn't seem to work for me.

apiVersion: v1 kind: Service metadata: name: webhook-eventsource namespace: argo-events spec: ports: - name: tcp port: 12000 protocol: TCP targetPort: 12000 selector: eventsource-name: webhook type: NodePort

Do you have any examples of how to implement it with ingress?

@Pzharyuk If you're exposing it through ingress, you just have to add Ingress resource that points to the Service.
