title: Kubernetes and istio sidecar automatic injection
body: <p>I'm trying to set up the automatic sidecar injection for istio on Kubernetes on-premises (istio 1.1.5 k8s 1.13.5).</p>
  
  <p>Once I labeled my namespace as <code>istio-injection=enabled</code> I got on my pod the following error for istio-sidecar container</p>
  
  <pre><code>Readiness probe failed: HTTP probe failed with status code: 503
  </code></pre>
  
  <p>If I try to inject manually the sidecar container it works.
  How can I solve?</p>
