<p>I could access the service as shown below</p>
<pre><code>export EXTERNAL_IP=$(kubectl get svc istio-ingressgateway -n istio-system -o jsonpath='{.status.loadBalancer.ingress[0].ip}')

curl -v --resolve web.zaalion.com:443:$EXTERNAL_IP --cacert cert2.crt https://web.zaalion.com
</code></pre>
<p>I do know why the service is not listed in the Jaeger UI?</p>

<p>According to istio <a href="https://istio.io/latest/docs/tasks/observability/distributed-tracing/jaeger/#generating-traces-using-the-bookinfo-sample" rel="nofollow noreferrer">documentation</a></p>
<blockquote>
<p>To see trace data, you must send requests to your service. The number of requests depends on Istio’s sampling rate. You set this rate when you install Istio. The default sampling rate is 1%. You need to send at least 100 requests before the first trace is visible. Could you try to send at least 100 requests and check if it works?</p>
</blockquote>
<p>If you wan't to change the default sampling rate then there is istio <a href="https://istio.io/latest/docs/tasks/observability/distributed-tracing/configurability/#customizing-trace-sampling" rel="nofollow noreferrer">documentation</a> about that.</p>
<blockquote>
<p><strong>Customizing Trace sampling</strong></p>
<p>The sampling rate option can be used to control what percentage of requests get reported to your tracing system. This should be configured depending upon your traffic in the mesh and the amount of tracing data you want to collect. The default rate is 1%.</p>
<p>To modify the default random sampling to 50, add the following option to your tracing.yaml file.</p>
</blockquote>
<pre><code>apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
spec:
  meshConfig:
    defaultConfig:
      tracing:
        sampling: 50
</code></pre>
<blockquote>
<p>The sampling rate should be in the range of 0.0 to 100.0 with a precision of 0.01. For example, to trace 5 requests out of every 10000, use 0.05 as the value here.</p>
