Hey everyone! I'm a student diving into my first project involving Kubernetes and Minikube, and I'm really stuck right now. I'm setting up a microservices project and trying to access my services using NodePort, which I thought was the standard starting point. Here's where I'm running into issues:
When I try to connect to my services using http://:, I get a 'Connection refused' error on my M1 Macbook. On my Windows PC, the connection just times out or I get an 'Unable to connect to the remote server' error when I use curl.
I've already tried a lot of different approaches. The `minikube service` command does work for opening my service in a browser, but when I try to open a tunnel, it doesn't seem to help. I can't rely on the `minikube service` command every time since it gives me a new URL each time I start it.
I've double-checked all my YAML files, and they seem fine. I'm using the Docker driver, and I've heard it might not be the best option. I feel like this is a fairly basic setup issue. If anyone has any advice or needs more info, I'd really appreciate the help!

Your machine needs a way to route traffic to the Minikube service. You could use 'kubectl port-forward' to reach it or follow a guide like the one found here: https://minikube.sigs.k8s.io/docs/handbook/accessing/.
If you're using the Docker driver, remember that your services are usually listening only on localhost, so you should try accessing them via http://localhost:. For quick tests, use 'kubectl port-forward' or 'minikube service --url'. If you need a real external IP, consider running 'minikube tunnel' or rebooting Minikube with a VM driver like Hyperkit or Hyper-V. Just make sure your firewall isn't blocking any ports!
It sounds like you might need to use port forwarding or set up an ingress for your services. That's a common step in getting them accessible outside the cluster.
When using Minikube with the Docker driver, there are some networking quirks to keep in mind. Minikube runs a Docker container that acts as your Kubernetes node, and typically, NodePort services aren't directly accessible from your host. That's why the `minikube service` command works—it handles the port forwarding for you! You might want to try that if you haven't already.
Great that you're learning Kubernetes! It might help to take a step back and understand some basics about networking and how Linux processes work. Connection issues can arise from firewalls, listening ports, and more. Sometimes, a little hypothesis testing can go a long way in debugging.
