Solving the IP-Address Issue with Ingress in Minikube 1.23 on Ubuntu 21.04

If you've recently started working with Kubernetes and are exploring the Ingress features, you may have run into a common issue — the Ingress not getting assigned an IP address in Minikube 1.23 when running on Ubuntu 21.04. This can be frustrating for beginners trying to configure their applications. Let's break down the problem and provide you with a solid solution.

Understanding the Problem

In your situation, you made adjustments to your Ingress configuration file in an attempt to make it compatible with the newer version of Kubernetes. However, even after your updates, you found that your Ingress resource did not have an IP address assigned to it. Here’s a quick recap of what you were experiencing:

You applied a new configuration for your Ingress resource, which is necessary for the proper functioning of your services.

When you checked the result with kubectl get ingress, the output showed that the address field was empty.

Logs from the Ingress pod indicated an error regarding a valid IngressClass being missing.

The Solution: Update Minikube

The good news is that you've encountered a known issue that has already been addressed. The error regarding the Ingress not being assigned an IP address is a bug in Minikube 1.23 that has been fixed in a later release. To resolve your issue, you simply need to update your Minikube installation to version 1.23.1 or higher. Here’s how you can do it:
