Unable to install Keda 2.7 operator with seurity securityContext added

Expected Behavior

With previous version:

 kubectl apply -f https://github.com/kedacore/keda/releases/download/v2.6.1/keda-2.6.1.yaml
namespace/keda configured
customresourcedefinition.apiextensions.k8s.io/clustertriggerauthentications.keda.sh configured

and both pods get started as expected:

Did it pick up because if there would be an issue then it should go in crashbackloop? What do the operator logs say?

@tomkerkhove no operator log as its deployment does not work - operator is prevented from starting AFAICT (I updated description to show that for 2.6.1 both pods are started and for 2.7 only one pod is runing)

Hi there,

I have the same issue than @aslom but for the version v2.11.2

I do the same oc apply -f https://github.com/kedacore/keda/releases/download/v2.11.2/keda-2.11.2.yaml and I get the same scc errors.

I am as well on OpenShift

Actually the issue appears again already in the v2.9.1
