We often use Pod Security Policies (PSPs) in Kubernetes to ensure that pods run with only restricted privileges. This layered approach allows you to adopt Istio in a more incremental fashion, smoothly transitioning from no mesh, to a secure L4 overlay, to full L7 processing and policy — on a per-namespace I discovered this by deleting my istio-system namespace, then installing with kubectl apply -f - <<EOF apiVersion: install. io/v1alpha1 kind: IstioOperator spec: profile: default components: egressGateways: - n The sidecar proxy now has the default requests set to.
