[fed-sv]

gha-runner-scale-set-0.9.3...gha-runner-scale-set-0.10.0#diff-fa8c7b8dda021d469814bb2923cb93b10a55a2852b7cd3496a3176e64a7dabe3R195

Hey @fed-sv

Can you please help me understand why is this change needed? There is only one listener per autoscaling runner set. We deployed it on the desired namespace, and install one scale set to that namespace.

hi @nikola-jokic , there are two changes, the first one it's replacing the hardcoded namespace arc-systems with the user entered namespace ${{inputs.arc-controller-namespace}}.
The other change, it's so that this task works when you have multiple listeners. For example in our workplace we have 5 different listeners. Not sure why this task was assuming only one listener?
