Ingress returning 404 with kubernetes-CodePudding

I'm trying to setup ingress to work with a kubernetes cluster as seen here:https://www.youtube.com/watch?v=DgVjEo3OGBI. When testing the endpoint in postman it is returning a 404 not found. I've tried using https and http and i'm at a loss. Thanks!

Edit: I was using a localhost for testing and am now trying to use acme.com as the routing url.

Ingress file:

CodePudding user response：

So there was a change in ingress.yml which I have made and it works for me can you test using the below manifest and check if its working ?

apiVersion: apps/v1
kind: Deployment
metadata:
  name: platforms-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: platformservice
  template:
    metadata:
      labels:
        app: platformservice
    spec:
      containers:
        - name: platformservice
          image: revlisc/platformservice:latest

apiVersion: v1
kind: Service
metadata:
  name: platforms-clusterip-service
spec:
  type: ClusterIP
  selector:
    app: platformservice
  ports:
  - name: platformservice
    protocol: TCP
    port: 80
    targetPort: 80

Also there was an issue with your ingress file as well i have made a small change. Check if this works for you

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-resource
  annotations:
    kubernetes.io/ingress.class: "nginx"
    ingress.kubernetes.io/rewrite-target: /$
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  rules:
  - host: <your-hostname>
    http:
      paths:
      - pathType: Prefix
        path: "/api/platforms"
        backend:
          service:
            name: platforms-clusterip-service
            port:
              number: 80

When I hit hostname/api/platforms I was able to see this output I am not sure if this is the expected result. Can you confirm ?
