Hi, when I deploy grafana with:
sudo minikube start --vm-driver=none
I can access Grafana with http://grafana.local with no issue, but I when I deploy it with
minikube start, it won’t work, I will get a:
grafana.local refused to connect.
All deployment, service, ingress are deploying OK.
Here are my deployment:

I use traefik as ingress:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:

namespace: monitoring
annotations:
kubernetes.io/ingress.class: traefik
spec:
rules:
- host: grafana.local
http:
paths:
- backend:
serviceName: grafana-local
servicePort: 3000
I have the same issue with pgadmin, and all my services, so it is not a grafana specific issue.
service:
➜ scripts kgs -n monitoring
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
grafana-local NodePort 10.99.115.28 3000:31349/TCP 15m
ingress:
➜ scripts kgi -n monitoring
NAME CLASS HOSTS ADDRESS PORTS AGE
grafana-ingress <none> grafana.local 80 9m47s
/etc/hosts
127.0.0.1 localhost grafana.local pgadmin.local
When I check my open ports, I get:
➜ scripts sudo netstat -nlpute
