Experimenting with Kubernetes on a 7.6 GB RAM VPS Running a resource-intensive platform like Kubernetes on small-scale server environments, especially on a Virtual Private Server (VPS) with only 7.6 GB of RAM, often leads to unexpected and frustrating problems. In this post, I'll share my experiences dealing with the "swap fire" issue while setting up Kubernetes on my own VPS and how I overcame it. My goal is to explain with concrete examples what can go wrong in such situations, why it goes wrong, and most importantly, what we need to pay attention to when setting up this kind of infrastructure. This experiment was purely for learning purposes. While running Kubernetes with such limited resources for production environments might not be very sensible, the knowledge I gained during this process sheds light on memory management and performance issues that can be encountered even in larger systems.…
