I am new to configuring Ingress rules for my Kubernetes cluster.
My Kubernetes cluster is deployed on Bare Metal. No cloud.
I followed this link to set up my nginx-controller with RBAC in my cluster.
This is what I have deployed :
# kubectl get all -n ingress-nginx
NAME READY STATUS RESTARTS AGE
pod/default-http-backend-7c5bc89cc9-ks6kd 1/1 Running 0 2h
pod/nginx-ingress-controller-5b6864749-8xbhf 1/1 Running 0 2h
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/default-http-backend ClusterIP 10.233.15.56 <none> 80/TCP 2h
service/ingress-nginx NodePort 10.233.38.84 <none> 80:31118/TCP,443:32003/TCP 2h
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
deployment.apps/default-http-backend 1 1 1 1 2h
deployment.apps/nginx-ingress-controller 1 1 1 1 2h
NAME DESIRED CURRENT READY AGE
replicaset.apps/default-http-backend-7c5bc89cc9 1 1 1 2h
replicaset.apps/nginx-ingress-controller-5b6864749 1 1 1 2h
Given that I have my setup, I want to access my grafana dashboard using a URL.
My grafana setup is working perfectly fine.
# kubectl get all -n default
NAME READY STATUS RESTARTS AGE
pod/grafana-67c6585fbd-4jl7p 1/1 Running 0 2h
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/grafana NodePort 10.233.5.111 <none> 3000:32093/TCP 2h
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
deployment.apps/grafana 1 1 1 1 2h
NAME DESIRED CURRENT READY AGE
replicaset.apps/grafana-67c6585fbd 1 1 1 2h
I can access the dashboard using http://10.27.239.145:32093 which is the IP of one of my K8S worker nodes.
Now rather than accessing via IP:NodePort, I want to access via URL e.g. grafana.test.mydomain.com
So the ingress rule that I configured in my default namespace is :
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
creationTimestamp: 2018-09-25T20:32:24Z
generation: 5
name: grafana
namespace: default
resourceVersion: "28485"
selfLink: /apis/extensions/v1beta1/namespaces/default/ingresses/jenkins-tls
uid: 1c51cece-c102-11e8-bf0f-02000a1bef39
spec:
rules:
- host: grafana.test.mydomain.com
http:
paths:
- backend:
serviceName: grafana
servicePort: 3000
path: /
On my local laptop from where I am testing, Ive added to my /etc/hosts the following entry :
10.27.239.145 grafana.test.mydomain.com
And in my browser, I am trying to access http://grafana.test.mydomain.com but I only get This site can’t be reached
grafana.test.mydomain.com refused to connect.
I have a strong feeling that I am missing out on something but can't figure it out.
I changed the NodePort to ClusterIP but no luck.
I know that my ingress controller is working since everytime I make a change to my ingress rules, I get logs from my ingress controller.

Any help will strongly be appreciated regarding what might I have missed.
