You **MUST** disable swap in order for the kubelet to work properly. Certain ports are open on your machines. Unique hostname, MAC address, and product_uuid for every node. Full network connectivity between all machines in the cluster (public or private network is fine). We'll use kubeadm to build a cluster that comes with minimum requirements: - One or more machines running one of: - Ubuntu 16.04+ - Debian 9+ - CentOS 7+ - Red Hat Enterprise Linux (RHEL) 7+ - Fedora 25+ - HypriotOS v1.0.1+ - Flatcar Container Linux (tested with 2512.3.0) - 2 GB or more of RAM per machine (any less will leave little room for your apps).

A lot of the tutorial is based on official documentation of components I used. My goal is to provide you with an easy-to-follow guide to get your first cluster and application up and running. I won't go into too much detail about the internal workings of the cluster or Kubernetes itself. Kubernetes being a container orchestration tool implies you'll want to run containerized applications. All you need to follow this guide is a basic understanding of networking concepts and some basic knowledge about containers. This makes Kubernetes unnecessarily hard to get into. Although you can find numerous guides for various applications, they often require you to be already familiar with Kubernetes or running a cluster in a cloud environment provided by major providers. Kubernetes has been around for a while now.
