kubectl get ing gives no address in kubernetes ingress

0 votes

I tried configuring ingress cluster. I ran the following commands

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/baremetal/service-nodeport.yaml

After that default-http-backend and nginx-ingress-controller were running:

ingress-nginx   default-http-backend-846b65fb5f-6kwvp      1/1       Running   0          23h       192.168.2.28   node1
ingress-nginx   nginx-ingress-controller-d658896cd-6m76j   1/1       Running   0          6m        192.168.2.31   node1

I tried testing ingress and I deployed the following service:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: echoserver-deploy
spec:
  replicas: 2
  selector:
    matchLabels:
      app: echo
  template:
    metadata:
      labels:
        app: echo
    spec:
      containers:
        - name: my-echo
          image: gcr.io/google_containers/echoserver:1.8
---
apiVersion: v1
kind: Service
metadata:
  name: echoserver-svc
spec:
  selector:
    app: echo
  ports:
    - protocol: TCP
      port: 8080
      targetPort: 8080

And the following ingress:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: happy-ingress
  annotations:
    INGRESS.kubernetes.io/rewrite-target: /
spec:
  rules:
    - host: happy.k8s.io
      http:
        paths:
          - path: /echoserver
            backend:
              serviceName: echoserver-svc
              servicePort: 8080

When I ran the command 'kubectl get ing' I received:

NAME            HOSTS          ADDRESS   PORTS     AGE
happy-ingress   happy.k8s.io             80        14m

You can check under which IP is the cluster working:

bash-3.2$ kubectl cluster-info
Kubernetes master is running at https://192.168.1.100:8443
KubeDNS is running at https://192.168.1.100:8443/api/v1/namespaces/kube- 
system/services/kube-dns:dns/proxy

Test the ingress controller for your cluster using curl

bash-3.2$ curl http://192.168.1.100:8080
default backend - 404

In the end, you should just add the domain entry to /etc/hosts :

192.168.1.100   happy.k8s.io

Because your hostname happy.k8s.io should resolve to an actual IP address of the nginx-ingress-controller, which points to the front of your load balancer.

Make sure you use the service type as Load balancer to get an external IP on your ingress or matter of fact any service that you try to deploy.

What if I use the service type as NodePort?
NodePort opens any one of the available port. You can also use NodePort but it might not give you an external IP though instead give a port that will be opened on all the nodes.
I find all the service types very confusing. Could you please explain how and where to use which service type? Thank you

Have a look at this thread, might give you a better clear understanding: https://www.edureka.co/community/19351/clusterip-nodeport-loadbalancer-different-from-each-other?

Have a look at this thread. I hope you get a clear understanding with it: https://www.edureka.co/community/19351/clusterip-nodeport-loadbalancer-different-from-each-other?

 I had the same problem and I solved it by hardcoding address in ingress controller. You can do it by adding "externalIPs" parameter in spec block (in ingress yaml)
