Kubernetes@Home – what do you do if your ISP changes your IP addresses?

The author described how they extended the external-DNS concept in Kubernetes to handle changes in their external IP addresses, which are controlled by their ISP. They programmed a solution using the Unifi API and implemented it as a Kubernetes deployment to automate the process of updating firewall rules and Kubernetes resources in case of IP address changes. The program utilizes the Unifi API, MQTT notifications, and IP address management to adapt to possible changes in external IP addresses.
