Currently, I'm using Docker Desktop with WSL2 integration. I found that Docker Desktop automatically had created a cluster for me. It means I don't have to install and use Minikube or Kind to create cluster. The problem is that, how could I enable Ingress Controller if I use "built-in" cluster from Docker Desktop? I tried to create an Ingress to check if this work or not, but as my guess, it didn't work.
The YAML file I created as follows:
apiVersion: apps/v1
kind: Deployment
metadata:
name: webapp
spec:
minReadySeconds: 30
selector:
matchLabels:
app: webapp
replicas: 1
template:
metadata:
labels:
app: webapp
spec:
containers:
- name: webapp
image: nodejs-helloworld:v1
---
apiVersion: v1
kind: Service
metadata:
name: webapp-service
spec:
selector:
app: webapp
ports:
- name: http
port: 3000
nodePort: 30090 # only for NotPort > 30,000
type: NodePort #ClusterIP inside cluster
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: webapp-ingress
spec:
defaultBackend:
service:
name: webapp-service
port:
number: 3000
rules:
- host: ingress.local
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: webapp-service
port:
number: 3000
I tried to access ingress.local/ but it was not successful. (I added ingress.local to point to 127.0.0.1 in host file. And the webapp worked fine at kubernetes.docker.internal:30090 )
Could you please help me to know the root cause? Thank you.
Finally I found the way to fix. I have to deploy ingress Nginx by command:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.41.2/deploy/static/provider/cloud/deploy.yaml
(Follows the instruction at https://kubernetes.github.io/ingress-nginx/deploy/#docker-for-mac. It works just fine for Docker for Windows)
Now I can access http://ingress.local successfully.
