<p>I'm running into issues trying to deploy stateful mongodb replicaset with sidecar from cvallance while running istio 0.8, if I leave istio out of the mix everything works, but when istio is enabled mongo-sidecars can't find eachother and replicaset is not configured. Below is my mongo deployment and service.</p>
