Report

Similar to what we experienced running Out Of Cluster mode in Karpenter here, when trying to run leader election in OutOfCluster mode (i.e when we pass a kubeconfig file as a launch arg), the KEDA operator crashes on launch with

unable to find leader election namespace: not running in-cluster, please specify LeaderElectionNamespace

I believe for KEDA since we have kedautil.GetPodNamespace() already, we can add

LeaderElectionNamespace: kedautil.GetPodNamespace(),

to the controller manager initializer .

Expected Behavior

When running in OutOfCluster mode with a passed in Kubeconfig, Leader Election should work.

Actual Behavior

KEDA crashes on launch with

unable to find leader election namespace: not running in-cluster, please specify LeaderElectionNamespace

Steps to Reproduce the Problem

1. Run KEDA-Operator in OutOfCluster mode by passing in kubeconfig file as launch arg
2. Enable Leader Election
