[🐛 Bug]: ScaledObject errors out when ServiceName has been used - GKE

[devqaio]

What happened?

I have setup my Cluster in GKE. Attached are my Configs fro my cluser and selenium grid.

When I use the service name in my ScaledObject trigger, it doesn't instantiate the POD. However, if I use the ClusterIP directly, then only it works.

It should work with the service name as well unless I am missing anything. It adds the request to queue using the service name. Hence I am ruling out the connectivity issues with service name. However, it doesn't create a new node/pod that was suppossed to be spinned up by ScaledObject making the node available for execution.

How about if you try this config for the triggers as below?

  triggers:
    - type: selenium-grid
      metadata:
        browserName: chrome
        sessionBrowserName: chrome
        unsafeSsl: 'true'
        url: 'http://selenium-hub-ci:4444/graphql'

@VietND96 - No luck.. It doesn't respond. I see the request in Queue to be assigned to a node. But my browser deployment doesn't splin up a pod. The script fails after 3 minute with a SessionNotCreatedException.

Moreover, I observed that using IP, creates a POD for me and keep it idle when the minReplica in ScaledObject and Replica count in deployment are 0. If I am not missing anything, I am expecting the deployment to be created/modified with out any pod available. Based on request, the pods should get splinned up dynamically

Moreover, the test fails if the pod doesn't get spinned up with in 3 minutes. My ingress timeout has been set to 100 minutes.
