<p>Grafana, service graph and zipking aren't deployed after the installation of Istio.There's no way to install these add-ons after the initial install of Istio?? </p>

<p>It depends on how did you install istio.</p>

<p>if installed with helm install, then you can install add-ons using command like this:</p>

<pre><code>helm upgrade istio istio-1.0.0/install/kubernetes/helm/istio --set grafana.enabled=true,servicegraph.enabled=true,tracing.enabled=true
</code></pre>

<p>or you installed with helm template, then you need to edit the values.yaml in your helm template directory to enable those add-ons, then install it:</p>

<pre><code>helm template install/kubernetes/helm/istio --name istio --namespace istio-system &gt; $HOME/istio.yaml
kubectl apply -f $HOME/istio.yaml
</code></pre>
