The host should be set if you want to use something else than

localhost

. Host is not required.

@aloof-controller-49647 but I could not able to access somehow even if I tried localhost or without host

Did you disable traefik?

yeah worked after i refactor my ingress

So it is fixed? If yes, what did you do?

I changed my ingress resource and add some annotations

Could you specify the changes explicitly?

this is how it looks like now

apiVersion: <http://networking.k8s.io/v1|networking.k8s.io/v1>
kind: Ingress
metadata:
  name: {{ include "frontend-service.fullname" . }}
  namespace: comnext
  annotations:
    <http://kubernetes.io/ingress.class|kubernetes.io/ingress.class>: "nginx"
    <http://nginx.ingress.kubernetes.io/service-upstream|nginx.ingress.kubernetes.io/service-upstream>: "true"
    <http://nginx.ingress.kubernetes.io/configuration-snippet|nginx.ingress.kubernetes.io/configuration-snippet>: |
      proxy_set_header l5d-dst-override frontend-service.comnext.svc.cluster.local;
      proxy_hide_header l5d-remote-ip;
      proxy_hide_header l5d-server-id;
spec:
  rules:
    - host: localhost
      http:
        paths:
          - backend:
              service:
                name: frontend-service
                port:
                  number: 80
            path: /
            pathType: ImplementationSpecific

💪

Note that if you run

kubectl explain --api-version=<http://networking.k8s.io/v1|networking.k8s.io/v1> Ingress.spec.ingressClassName

you will see:

DESCRIPTION:
     IngressClassName is the name of the IngressClass cluster resource. The
     associated IngressClass defines which controller will implement the
     resource. This replaces the deprecated `<http://kubernetes.io/ingress.class|kubernetes.io/ingress.class>`
     annotation.

So at some point, you will need to remove the

<http://kubernetes.io/ingress.class|kubernetes.io/ingress.class>

annotation and change your

spec

section to:

spec:
  ingressClassName: nginx
  rules:
    - host: localhost
      http:
        paths:
          - backend:
              service:
                name: frontend-service
                port:
                  number: 80
            path: /
            pathType: ImplementationSpecific

@orange-tent-50778 you re right.. By the way, when I remove localhost, i am getting an error that host required.. Should I speficy the host in rancher-desktop to access my app

I don't know if this is the best approach but this is that I have setup for our project (the project is called The Combine which will help explain some of the names):

apiVersion: <http://networking.k8s.io/v1|networking.k8s.io/v1>

I am using helm so I removed the parts added by it. I am also using cert-manager.io to create a self-signed certificate. Secondly, I have updated my

/etc/hosts

to contain:

127.0.0.1	localhost thecombine.local

Last of all, I setup the port forwarding in Rancher Desktop to forward 37700 to the

ingress-nginx

https port. Now I can access my front end by navigating to

<https://thecombine.local:37700>

. Since it has a self-signed certificate, I need to assure the browser that I know what I am doing and accept the risk.

How do you access backend services if you have any frotnend service ?
