General Discussions

Hello I am quite new to kubernates I have used ad work but now I need to use it on premesis (I only have 1 machine),
So I have installed kubernates on an Ubuntu DPS
then I have also added ngnx-ingress-controller kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.35.0/deploy/static/provider/baremetal/deploy.yaml

then I have my deployment (react app):
apiVersion: apps/v1

kind: Deployment
metadata:
  name: clientweb-dep
  labels:
    appcluster: ethernial
    app: clientweb
spec:
  replicas: 1
  selector:
    matchLabels:
      app: clientweb
  template:
    metadata:
      name: clientweb-template
      labels:
        appcluster: ethernial
        app: clientweb
    spec:
      containers:
      - name: clientweb
        image: ethernial.azurecr.io/clientweb
        resources:
          requests:
            cpu: 100m
            memory: 300Mi
        env:
        - name: APPNAME
          value: clientweb
        - name: CONTAINERNAME
          value: clientweb
        ports:
        - containerPort: 80
          name: http-port
      imagePullSecrets:
      - name: acr-secret

and this is my servie:
apiVersion: v1

kind: Service
metadata:
  labels:
    appcluster: ethernial
    app: clientweb
  name: clientweb-service
spec:
  ports:
  - port: 80
    name: http
  selector:
    app: clientweb
  type: ClusterIP

and this is the ingress:
apiVersion: extensions/v1beta1

kind: Ingress
metadata:
  name: clientweb-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  rules:
    - http:
        paths:
          - path: /?(.*)
            backend:
              serviceName: clientweb-service
              servicePort: 80

But when I got to the ip or domain URL I get 502 Bad Gateway (also I need to know how to configure domain or subdomains), so what I am missing?

kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
clientweb-service ClusterIP 10.103.212.174 80/TCP 132m
kubernetes ClusterIP 10.96.0.1 443/TCP 48d

kubectl get ingress
NAME CLASS HOSTS ADDRESS PORTS AGE
clientweb-ingress * 62.75.216.101 80 31m

the address is the address of my DPS, and it is correct

kubectl describe ing clientweb-ingress
Name: clientweb-ingress
Namespace: default
Address: 62.75.216.101
Default backend: default-http-backend:80 (<error: endpoints “default-http-backend” not found>)
