So we have built a control plan from scratch. That’s kinda useful and was also kinda hard to make? But, really what we want to make is a proper, functioning, multi-node cluster that can actually run our containerized applications. A control plane by itself is just the brain; we need the muscle (the worker nodes) to do the actual work. When we set up the control node, setting up the Control Plane required us to manually configure every single detail of the seed VM, line-by-line. While that was an important exercise in understanding the components, trying to repeat those steps for 10, 50, or 100 worker nodes would quickly become a nightmare. This part of the series is about making the process scalable by creating a “Golden Image” from our pre-configured machine, allowing us to rapidly provision identical workers and efficiently join them to our existing cluster. Creating a Golden Image The core principle here is to stop doing repetitive manual configuration.…
