<p>I'm following the <a href="https://cloud.google.com/kubernetes-engine/docs/tutorials/installing-istio" rel="nofollow noreferrer">tutorial for Istio</a> on the Google Cloud Platform and have been able to get my cluster up and running. I get to part where I start the demo app by running <code>kubectl apply -f install/kubernetes/istio-demo-auth.yaml</code> but a number of the pods wont come up.</p>

<p>I'm running Istio 1.0.3</p>

<pre><code>kubectl version --short
Client Version: v1.11.1
Server Version: v1.9.7-gke.6
</code></pre>

<p>When I run the command <code>kubectl get service -n istio-system
</code> to verify istio pods are deployed and containers are running many of them are in crash cycles. Any tips on how to debug this?</p>

<p>That looks like the output for <code>kubectl -n istio-system get pods</code></p>

<p>Tips, check the output for these:</p>

<ul>
<li><code>$ kubectl -n istio-system logs istio-pilot-d6b56bf4d-czp9w</code></li>
<li><code>$ kubectl -n istio-system logs istio-policy-6c7d8454b-dpvfj</code></li>
<li><code>$ kubectl -n istio-system logs istio-grafana-post-install-n45x4</code></li>
<li><code>$ kubectl -n istio-system logs istio-telemetry-69db5c7575-4jp2d</code></li>
<li>Check the deployment/service/configmap definitions in <code>install/kubernetes/istio-demo-auth.yaml</code> that you have pods crashing for.</li>
</ul>
