[🚀 Feature]: Selenium Grid Helm Chart: Do Not Patch Keda If Disabled

[AndreasPetersen]

Feature and motivation

We have disabled autoscaling on our Selenium Grid:

autoscaling:
  enabled: false

But when we update the grid, Keda is still patched, because

https://github.com/SeleniumHQ/docker-selenium/blob/trunk/charts/selenium-grid/templates/patch-keda/patch-keda-objects-job.yaml#L1

does not check if autoscaling is also enabled.

This unexpectedly caused some issues for us, as we were not expecting Keda to patch. Specifically we need to fetch our Docker images through a corporate Artifactory, so the default kubectlImage was being blocked, causing upgrade failure.

I propose that patching of Keda is disabled if autoscaling is disabled.

Usage example

Setting

autoscaling:
  enabled: false

in values.yaml will disable Keda patching.

Hi, for the reason the patch job is running even autoscaling.enabled: false to ensure cleanup in case upgrade an existing deployment with enabled autoscaling to disabled autoscaling. Of course, I agree that it will cause annoying for common usage. Will update another mechanism for this. In the meantime, you can use config autoscaling.patchObjectFinalizers.enabled to disable it separately.

Thanks for the quick reply @VietND96 .

Like you said, I specifically disabled the patcher, and upgrading the grid then works as expected.
