kubectl describe node docker-for-desktop This gets the IP address of Docker desktop for Windows.
But we run it on browser with ip:nodeport it is not working.
nodeport - is the port number that we mention in the services file of kubernetes cluster.
Please find myservice.yaml file in the code section.
apiVersion: v1
kind: Service
metadata:
name: xxxx
spec:
# This defines which pods are going to be represented by this Service
# The service becomes a network endpoint for either other services
# or maybe external users to connect to (eg browser)
selector:
mykey: webapp
release: "0-5"
ports:
- name: http
port: 80
nodePort: 30080
#this is port number greater than 30000, and it is port of the Node where this cluster is present.
type: NodePort
http://<dockerDesktopIdaddress>:<nodeport>
nodeport is the port number in the service file of kubernetes cluster.
always gives error.
Docker For Windows , Docker For MAC , or Docker for anything uses minikube for kubernetes , and you need to get the external ip of minikube machine.
You need the external IP instead of internal IP , the kubectl is showing only the internal IP.

As suggested in the comments , if you don't want to see inside the minikube machine , you can use the following command to get the external IP:
minikube ipI had the same issue and the resolution was simple. curl localhost:$NODE_PORT
Docker for Mac runs on the same host and you can call the service through localhost.
