title: Can't access Mongo from Node container running in Istio
body: <p>I'm trying to run a stateful Mongo inside Kubernetes and it works with these configurations outside of Istio.</p>
  
  <pre><code>  mongodb: {
      uri: "mongodb://mongo-0.mongo,mongo-1.mongo,mongo-2.mongo",
      dbName: "app"
    }
  </code></pre>
  
  <p>But when I run the node application inside Istio, it loses the ability to connect to the mongo. Is there something I'm missing or is it so that I can't use stateful-sets with Istio yet?</p>
