Hi, I’m trying to deploy the PMM Server on k8s as a Deployment using this sample file:https://raw.githubusercontent.com/percona-platform/dbaas-controller/main/deploy/pmm-server-minikube.yaml
I set replicas to one.
But I encountered following errors when I deleted the pmm server pod.

So, I have checked the POD status and I found that there two pod at the moment.
default pmmserver-sample-b7dd8bccb-jzztt 2/2 Running 0 7s
default pmmserver-sample-b7dd8bccb-kzfcw 2/2 Terminating 0 4m45s
Can the PMM Server be deployed on k8s as a Deployment object?
