We also need to execute these commands on each of the worker nodes: sudo ufw allow 10251/tcp Use the following commands on your master node to do so: sudo ufw allow 6443/tcp Now open the /etc/hosts file and edit the hostnames for your worker nodes: sudo cat > /etc/hostsДЇor seamless communication across multiple nodes, we need to define rules in firewall. Set the appropriate hostnames for your master and worker nodes: sudo hostnamectl set-hostname 'master-node'Д®xec bash sudo hostnamectl set-hostname 'w-node1'

Use our guide on How to install Docker on your Ubuntu 18.04 Step 2. How to install Kubernetes on Ubuntu 18 Step 1.

User with sudo or root privileges on every server.

Multiple Ubuntu 18 VMs ( Cloud Servers) to house the MasterВ and worker nodes.

We offer a VLAN add-on to our Cloud Servers for R200 per month. In order to connect your nodes or VMs and make them private, make sure to choose a hosting company who provides a Virtual Local Area Network (VLAN) with their VMs. Pods are connected over a network and share storage resources. Kubernetes groups containers into pods, its most basic operational unit, which are basically just groups of containers running on the same node. However, if you want to install a different underlying container runtime, you can harness the power of the Container Runtime Interface and use basically any runtime you want. The most popular and recommended one is Docker, and itвЂ™s the one we will use for the purpose of this guide. Containers in this case are not virtualised servers but rather a solution that packages code and dependencies to run a single application (service) in an isolated (containerised) environment, essentially disassociating applications from the host machine.

You can manage this cluster from the command line on your kubemaster node.Д®very Kubernetes instance runs on top of a container runtime, which is software responsible for managing container operations. Once they have been installed and other configurations done, you will be able to create your first k8s cluster.

The k8s installationвЂ™s three core modules: Kubelet, kubeadm, and kubectl are agents that control the node and communicate with the Kubernetes Master. We strongly recommend you only use VMs aka Cloud Servers to run Kubernetes, not system containers aka VPS, as these can cause issues with k8s.ДЄ node is comprised of the Kubelet, a container runtime, and the kube-proxy. A node is a VM that serves as a worker machine in your k8s cluster to host running applications. The Master is the virtual machine (VM) that administers all activities on your cluster. Add nodes to your Kubernetes cluster What is a Kubernetes Cluster?ДЄ Kubernetes cluster consists of a Master and at least one to several worker node(s). Set up Flannel as the pod network for the Cluster

ItвЂ™s the go-to way to automate the deployment, scaling, and maintenance of containerised applications across different nodes.
