Kubernetes: Unable to configure Nginx Ingress to access an internal service - docker

Question

I am following a tutorial to access a pod running inside a Kubernetes cluster behind a service. This Kubernetes cluster is running on Windows 10 using Desktop Docker (by enabling the Kubernetes option)
I am unable to access it using this https://local.ticket.dev/api/users/currentuser it always says "Site can't be reached: local.ticket.dev unexpectedly closed the connection."
I have disabled the redirect but it still redirects HTTP to HTTPs
Request URL: http://local.ticket.dev/api/users/currentuser
Request Method: GET
Status Code: 307 Internal Redirect
Referrer Policy: strict-origin-when-cross-origin
Location: https://local.ticket.dev/api/users/currentuser
Non-Authoritative-Reason: HSTS
Here is visually what I want
kubectl get ing
NAME CLASS HOSTS ADDRESS PORTS AGE
ingress-service <none> local.ticket.dev 80 29s
kubectl get services
Please note it's running on local machine windows 10 with Docker Desktop. and the LoadBalancer external IP always remain pending even after 6 hours
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
auth-srv ClusterIP 10.96.254.94 <none> 3000/TCP 45s
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 5h17m
nginx-ingress-1629401528-controller LoadBalancer 10.110.199.210 <pending> 80:31430/TCP,443:32346/TCP 5h13m
nginx-ingress-1629401528-default-backend ClusterIP 10.108.79.252 <none> 80/TCP 5h13m
kubectl get pods
NAME READY STATUS RESTARTS AGE
auth-depl-c98cdf66f-txqxt 1/1 Running 0 54s
nginx-ingress-1629401528-controller-569576ddbd-2htxz 1/1 Running 0 5h13m
nginx-ingress-1629401528-default-backend-69c7fc6549-xxf8w 1/1 Running 0 5h13m
How I configured it is as follows
1 - Installation of Nginx by the following command
helm install stable/nginx-ingress --generate-name
2 - Skaffold dev

if I look at the last line it seems that my Auth Pod is running on 3000 port.

Answer 1

First Disable the HTTPS redirect first
nginx.ingress.kubernetes.io/ssl-redirect: "false"
add annotation into the ingress
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/ssl-redirect: "false"
spec:
rules:
- host: local.ticket.dev
http:
paths:
- path: /api/users/?(.*)
pathType: Prefix
backend:
service:
name: auth-srv
port:
number: 3000
Did you get the external IP for Nginx controller svc? it's showing pending as you are on the Local system.
You might also need to add entries into host file
manually adding your ingresses' hostnames to /etc/hosts:
127.0.0.1 ingress.local
127.0.0.1 local.ticket.dev
OR
Host IP local.ticket.dev
