I am following this tutorial for setting up Ingress with Ingress-Nginx on Minikube. But I can't seem to get it to work. I get a connection refused when I try to connect to port 80 on the VM IP address returned by minikube ip
My setup is this:
The ingress-nginx namespace has the below resources:
NAME READY STATUS RESTARTS AGE
pod/ingress-nginx-controller-85f4c5b458-2dhqh 1/1 Running 0 49m
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/ingress-nginx-controller NodePort 10.102.88.109 <none> 80:30551/TCP,443:31918/TCP 20h
service/ingress-nginx-controller-admission ClusterIP 10.103.134.39 <none> 443/TCP 20h

NAME COMPLETIONS DURATION AGE

The default namespace has the below resources
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
pod/web-79d88c97d6-rvp2r 1/1 Running 0 47m 10.244.1.4 minikube-m02 <none> <none>

service/kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 20h <none>
service/web NodePort 10.104.20.14 <none> 8080:31613/TCP 20h app=web
NAME CLASS HOSTS ADDRESS PORTS AGE
ingress.networking.k8s.io/example-ingress nginx hello-world.info localhost 80 20h
Minikube is exposing these services:
|---------------|------------------------------------|--------------|-----------------------------|
| NAMESPACE | NAME | TARGET PORT | URL |
|---------------|------------------------------------|--------------|-----------------------------|
| default | kubernetes | No node port |
| default | web | 8080 | http://192.168.59.106:31613 |
| ingress-nginx | ingress-nginx-controller | http/80 | http://192.168.59.106:30551 |
| | | https/443 | http://192.168.59.106:31918 |
| ingress-nginx | ingress-nginx-controller-admission | No node port |
| kube-system | kube-dns | No node port |
| kube-system | registry | No node port |
|---------------|------------------------------------|--------------|-----------------------------|
In step 4 of the Create an Ingress section The tutorial mentions this:
Add the following line to the bottom of the /etc/hosts file on your computer (you will need administrator access):
172.17.0.15 hello-world.info
Note: If you are running Minikube locally, use minikube ip to get the external IP. The IP address displayed within the ingress list will be the internal IP.
It's a three node cluster using VirtualBox. I've tried adding the Minikube ingress-nginx-controller service's IP (192.168.59.106, which is also the result of minikube ip) to my hosts file, but it doesn't work. And as far as I know, I can't include the service's node port 30551 in the hosts file to test that.
Some guidance on how to get this working would be much appreciated
When following the tutorial, I enabled the ingress addon after creating my cluster by running minikube addons enable ingress
This appeared to succeed, but when trying to connect to port 80 on the IP address returned by minikube ip (which is also the ingress-nginx-controller minikube service address), I got a connection refused. This can be validated by running:
nc -zv $(minikube ip) 80
However, when I enabled ingress at the time of initial cluster creation with this command:
minikube start --driver=virtualbox \
--kubernetes-version=v1.22.5 --nodes 3 \
--addons=ingress
and then ran nc -zv $(minikube ip) 80, the connection was accepted. I'm not sure if this is an issue with Minikube or with VirtualBox, but enabling ingress at the initial cluster creation time rather then subsequently worked for me
I was then able to update my hosts file with just the IP of the minikube node and the hello-world.info host
One thing that might also be worth noting if you create and delete your clusters a lot, I found sometimes when updating the hosts file on a Mac that old IPs were being cached. Running sudo dscacheutil -flushcache may help with this
