In terminal I run minikube ip to get external ip is 192.168.49.2, then run curl 192.168.49.2:31856, it is timeout don't return response

I try to stand in minikube node minikube ssh and try again curl 192.168.49.2:31856 it returns a response success. I think maybe there was a mistake about the docker desktop's network but can't find to fix

I continue to use port-forward by command kubectl port-forward --address 0.0.0.0 service/web-service 80:80 to forward by port service 80

run curl localhost:80, it has the response success same when ssh into minikube

I try curl 192.168.49.2:80

I think have a config to can connect ip of minikube node from outside but I still not to find right. Please help me if you have any ideal to do.

Thanks!

Answer 1

if you're using minikube then i would recommend to use the minikube tunnel command to access your services.

minikube service <service-name> --url
