How to access kubernetes dashboard with ingress and minikiube
Question
I'm trying to follow a tutorial of exposing the k8s dashboard using minikube and ingress. Basically what I have is the following ingress blueprint:
apiVersion: v1
items:
- apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
kubectl.kubernetes.io/last-applied-configuration: |
{"apiVersion":"networking.k8s.io/v1","kind":"Ingress","metadata":{"annotations":{},"labels":{"name":"dashboard-ingress"},"name":"dashboard-ingress","namespace":"kubernetes-dashboard"},"spec":{"rules":[{"host":"dashboard.com","http":{"paths":[{"backend":{"service":{"name":"kubernetes-dashboard","port":{"number":80}}},"path":"/","pathType":"Prefix"}]}}]}}
creationTimestamp: "2023-01-11T12:41:25Z"
generation: 1
labels:
name: dashboard-ingress
name: dashboard-ingress
namespace: kubernetes-dashboard
resourceVersion: "213743"
uid: ffe793ff-b985-4560-84d3-981007f7f309
spec:
ingressClassName: nginx
rules:
- host: dashboard.com
http:
paths:
- backend:
service:
name: kubernetes-dashboard
port:
number: 80
path: /
pathType: Prefix
status:
loadBalancer:
ingress:
- ip: 192.168.49.2
kind: List
metadata:
In my host file I have added the following line:
192.168.49.2 dashboard.com
That is how my host file looks like:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
# Added by Docker Desktop
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
127.0.0.1 dashboard.com
# End of section
When I curl dashboard.com I get the following output:
* Trying 127.0.0.1:80...
* connect to 127.0.0.1 port 80 failed: Connection refused
* Trying 2606:4700:3032::6815:11fe:80...
* Connected to dashboard.com (2606:4700:3032::6815:11fe) port 80 (#0)

I can normally access the dashboard by running minikube dashboard .
I'm new in k8s. As I can see, the IP address 192.168.49.2 is an external IP address. Adding it to my host file won't help I guess as it does not work anyway. (minikube tunnel has to be configured, I tried it several times, but it does not work)
I'm using Mac M1.
My docker version is: 20.10.21 My minikube version is: 1.28.0 My kubectl version is: 1.25.2
What am I missing?

So, I did it by closing my terminal with the tunnel and starting a new one. Basically with minikube, any new change that affects external IP addresses a new tunnel has to be started: minikube tunnel
