Kubernetes - Ingress on docker driver - minikube 1.16 - docker

Question

I'm trying to setup ingress on docker driver for minikube 1.16 on windows 10 home (build 19042).
Ingress on docker driver wasn't supported before but it is now on minikube 1.16:
https://github.com/kubernetes/minikube/pull/9761
I've been trying something by myself but i got ERR_CONNECTION_REFUSED when connecting to the ingress at 127.0.0.1 OR kubernetes.docker.internal
Steps:
minikube start
minikube addons enable ingress
create deployment
create ClusterIP
Ingress config
Here is my configuration:
#cluster ip service
apiVersion: v1
kind: Service
metadata:
name: client-cluster-ip-service
spec:
type: ClusterIP
selector:
component: web
ports:
- port: 3000
targetPort: 3000
# not posting deployment code because it's not relevant, but there is a deployment with selector 'component:web' and it's exposing port 3000.
#ingress service
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: 'true'
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: kubernetes.docker.internal
http:
paths:
- path: /?(.*)
pathType: Prefix
backend:
service:
name: client-cluster-ip-service
port:
number: 3000
I have dns redirect in hosts file.
I've also tried "minikube tunnel" on another terminal but no luck either.
Thanks!

There is a mistake in your ingress object definition under rules field:
rules:
- host: kubernetes.docker.internal
- http:
paths:
The exact problem is the - sing in front the http which makes the host and http separate arrays.
Take a look how your converter yaml looks like in json:
{
"spec": {
"rules": [
{
"host": "kubernetes.docker.internal"
},
{
"http": {
"paths": [
{
"path": "/?(.*)",
"pathType": "Prefix",
"backend": {
---
This is how annotations looks like with your ingress definition.
spec:
rules:
- host: kubernetes.docker.internal
http:
paths:
- path: /?(.*)
pathType: Prefix
And now notice how this yaml converted to json looks like:
{
"spec": {
"rules": [
{
"host": "kubernetes.docker.internal",
"http": {
"paths": [
{
"path": "/?(.*)",
"pathType": "Prefix",
"backend": {
---
You can easily visualize this even better using yaml-viewer
