<p>I am running a 2-node K8s cluster on OVH Bare Metal Servers. I've set up <strong>MetalLB</strong> and <strong>Nginx-Ingress</strong>.The 2 servers both have public IPs and are not in the same network segment. I've used one of the IPs as the entrypoint for the LB. The deployments I created 3 nginx containers &amp; services to test the forwarding.
When I use host based routing, the endpoints are reachable via the internet, but when I use path based forwarding, only the / path is reachable. For the rest, I get the default backend.
My host based Ingress resource:</p>
<pre><code>apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-resource-2
spec:
  ingressClassName: nginx
  rules:
  - host: nginx.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: nginx-deploy-main
            port:
              number: 80
  - host: blue.nginx.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: nginx-deploy-blue
            port:
              number: 80
  - host: green.nginx.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:

            name: nginx-deploy-green
            port:
              number: 80
</code></pre>
<p>The path based Ingress resource:</p>
<pre><code>apiVersion: networking.k8s.io/v1

</code></pre>
<p>I'm not sure what the issue is, and I can't figure out why it's working when I use different hosts, and not working when I try to use different paths.</p>
<p>I thought it could be resource limits, but I only have the requests, no limits. There is already a default IngressClass</p>
<p>I installed the ingress controller via manifests following the steps <a href="https://docs.nginx.com/nginx-ingress-controller/installation/installation-with-manifests/" rel="nofollow noreferrer">here</a></p>
<p>Update: To add the deployments running in the cluster.</p>

<p>I believe the reason is that the <code>nginx</code> service you have deployed for &quot;blue&quot; and &quot;green&quot; deployments are not serving anything on the <code>/blue</code> and <code>/green</code> endpoints. You need to create these endpoints inside <code>nginx</code> so that they become valid. Your ingress objects appear fine.</p>
<p>That's also why you see <code>/</code> working in all cases since by default <code>nginx</code> is hosting a web page on the path <code>/</code> but not on the paths <code>/blue</code> and <code>/green</code>. Simply creating the respective endpoints in your services for <code>nginx</code> should fix the problem.</p>
