Summary

In this chapter, we learned how to install K3s using the k3OS, a production-ready Linux distribution, covering how to prepare your VMs in case that you want to create a cluster for x86_64 architectures. Then, we moved on to explain how configuration files are used to perform advanced and custom cluster installations, and how you can configure them to create a multi-node cluster using the ISO image or the overlay installation. Finally, we covered how to create a multi-node cluster using the overlay installation, to reduce the manual configurations to install K3s using the k3OS potential. Now, we are close to starting use cases and real configuration in the coming chapters. In the next chapter, we are going to create a production-ready cluster using all the things that we learned in the previous chapters.
