<p>I managed to install kubernetes 1.22, longhorn, kiali, prometheus and istio 1.12 (profile=minimal) on a dedicated server at a hosting provider (hetzner).</p>
<p>I then went on to test httpbin with an istio ingress gateway from the istio tutorial. I had some problems making this accessible from the internet (I setup HAProxy to forward local port 80 to the dynamic port that was assigned in kubernetes, so port 31701/TCP in my case)</p>
<p>How can I make kubernetes directly available on bare metal interface port 80 (and 443).</p>
<p>I thought I found the solution with metallb but I cannot make that work so I think it's not intended for that use case. (I tried to set EXTERNAL-IP to the IP of the bare metal interface but that doesn't seem to work)</p>
<p>My HAProxy setup is not working right now for my SSL traffic (with cert-manager on kubernetes) but before I continue looking into that I want to make sure. Is this really how you are suppose to route traffic into kubernetes with an istio gateway configuration on bare metal?</p>
<p>I came across <a href="https://stackoverflow.com/questions/51331902/kubernetes-with-istio-ingress-not-running-on-standard-http-ports-443-80">this</a> but I don't have an external Load Balancer nor does my hosting provider provide one for me to use.</p>

<p>The solution for the issue is:</p>
<blockquote>
<p>I setup HAProxy in combination with Istio gateway and now it's working.</p>
</blockquote>
<p>The reason:</p>
<blockquote>
<p>I think the reason why SSL was not working was because  <a href="https://istio.io/latest/docs/setup/additional-setup/gateway/" rel="nofollow noreferrer">istio.io/latest/docs/setup/additional-setup/gateway</a>  creates the ingress gateway in a different namespace  (<code>istio-ingress</code>) from the rest of the tutorials (<code>istio-system</code>).</p>
