integration allows Cilium to enforce HTTP L7 network policies for mTLS protected traffic within the Istio sidecar proxies. Note that Istio can also be deployed without Cilium integration by running a standard version version of istioctl. In that case Cilium will enforce HTTP L7 policies outside of the Istio sidecar proxy, but that will only work if mTLS is not used. If you haven’t read the Introduction to Cilium & Helm. Without this option, when Cilium does service resolution via socket load balancing, Istio sidecar will be bypassed, resulting in loss of Istio features including encryption and telemetry. Step 2:
