Cluster information:
Minikube version: v1.11.0
Host OS: Ubuntu 20.04
I’m trying to install Grafana in a minikube local cluster with minikube 1.13.0
Here is the whole process:
minikube start # this step is OK
I deploy Grafana with:
kubectl config use-context minikube
kubectl create namespace monitoring --dry-run=client -o yaml | kubectl apply -f -
kubectl create secret generic grafana-env --from-env-file=.env.local --namespace=monitoring --dry-run=client -o yaml | kubectl apply -f -
kubectl apply -f deployment/local/grafana-pvc.yml
kubectl apply -f deployment/local/grafana-secret.yml
kubectl apply -f deployment/local/grafana-deployment.yml
kubectl apply -f deployment/local/grafana-svc.yml
kubectl apply -f deployment/local/grafana-ingress-local.yml

I also added a grafana.local entry in /etc/hosts to link it to 127.0.0.1
Pod, service, and ingress are deployed successfully, I see no errors.
But when I try to access it through chrome, I get a ERR_CONNECTION_REFUSED error.
It is important to say that before, I was starting minikube with the none driver, and it was working well:
sudo minikube start --vm-driver none
Also, when I do:
minikube dashboard
I can access the dashboard with no problem.
Also, if I do:
kubectl -n monitoring port-forward svc/grafana-local 3000
I will be able to access Grafana on http://127.0.0.1:3000.
but isn’t it the same thing than
ports:
- port: 3000
What am my missing ?
