serivce.yml

apiVersion: v1
kind: Service
metadata:
  name: frontend
spec:
  selector:
    app: frontend
  type: LoadBalancer
  ports:
    - protocol: TCP
      port: 3000
      targetPort: 3000
      nodePort: 30012
  externalIPs:
    - 192.168.64.2

I tried to access it on the browser using 192.168.64.2:30012 and 192.168.64.2:3000 but none worked

I did minikube servvice service-name still did not work

Have you checked whether there are any firewall rules blocking your application from reaching the browser. Follow this [link](https://support.apple.com/en-in/guide/mac-help/mh34041/mac) for validating your firewall settings in mac os. — Kranthiveer Dontineni, Apr 14 '23 at 11:50
@etranz since you have found this comment useful for better visibility of the community I’m converting it to an answer and adding a few more points, revert back if you are still facing any issues. — Kranthiveer Dontineni, Apr 15 '23 at 14:48

In general when you are deploying workloads on a personal computer, there are chances for a firewall to block your application ports from reaching outside. To mitigate this issue you have to check the firewall rules and add them if required.

This official macOS documentation contains information on how to manage firewall rules, go through this documentation and make necessary changes so that you can access your application using the browser.

Also as per the official minikube documentation sometimes Node IP might not be reachable directly in such scenarios you need to create a tunnel for your NodePort service using minikube. Follow the below steps taken from official docs for creating the tunnel using the minikube command:

minikube service (service name) --url
