Debugging a failing simple minikube ingress involves troubleshooting and verifying various components of the setup. Here are some steps to help you debug the issue:

  1. Verify minikube status: Ensure that minikube is running and properly configured by executing the following command: minikube status
  2. Verify ingress addon: Check if the ingress addon is enabled in minikube by running: minikube addons list Ensure that the ingress addon is listed and enabled. If not, enable it using the command: minikube addons enable ingress
  3. Verify ingress controller deployment: Ensure that the ingress controller is deployed and running. Check the status of the ingress controller's pods using: kubectl get pods -n kube-system Look for the pods with names starting with "ingress-nginx". If they are not in the "Running" state, there may be an issue with the ingress controller deployment.
  4. Verify ingress resource: Check if the ingress resource is properly defined and applied to the desired service. Run the following command to view the ingress resource: kubectl get ingress Verify that the ingress resource is present and correctly configured with the desired service and rules.
  5. Check DNS resolution: Ensure that the DNS resolution for the ingress domain is correct. You can add an entry to the /etc/hosts file on your local machine to map the ingress domain to the minikube IP address.
  6. Verify networking setup: Check if the networking setup is correct. Execute the following command to view the services and their associated IPs: kubectl get services Verify that the service associated with the ingress resource is exposed on a valid IP.
  7. Check ingress controller logs: If the above steps didn't reveal any issues, check the logs of the ingress controller pods to identify any error messages or warning signs: kubectl logs
  8. Verify firewall rules: If you are running minikube on a cloud platform or virtual machine, ensure that the necessary firewall rules are configured to allow ingress traffic to reach the cluster.


By following the above steps, you can systematically identify and debug the failing simple minikube ingress setup.
