How to write psp k8s for service account?

Question

Kubernetes

minikube start --extra-config=apiserver.enable-admission-plugins=PodSecurityPolicy --addons=pod-security-policy

there is a service account nginx-sa
created a role and rolebinding

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nginx-sa
  namespace: default

---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nginx-sa-role
  namespace: default
rules:
  - apiGroups: ["extensions", "apps",""]
    resources: [ "deployments","pods" ]
    verbs: ["get", "list", "watch", "create", "update", "patch", "delete"]

---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nginx-sa-role-binding
  namespace: default
subjects:
  - kind: ServiceAccount
    name: nginx-sa
    namespace: default
roleRef:
  kind: Role
  name: nginx-sa-role
  apiGroup: rbac.authorization.k8s.io

I want to run a container under this account

kubectl run nginx --image=nginx -n default --as system:serviceaccount:default:nginx-sa

I get an error

Error: container has runAsNonRoot and image will run as root (pod: "nginx-deployment-55649fd747-hdbql_default(2fe4a503-aa56-4ca4-9e4d-4c67cfedef40)", container: nginx)

The error is related to the one with psp . tell me, please, how to write the correct policy for namespace default, so that the service account is allowed to launch the pod without root rights?
