The Kubernetes scheduler determines the best available node on which to deploy newly created pods. Turn the swap off (for performance reason) Ping the worker nodes to verify that the hostfile changes are working fine. In case you don’t have access to the DNS, update /etc/hosts file on master and worker nodes with the following information: ~]# cat /etc/hostsġ27.0.0.1 kmaster-centos7ġ27.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 You can add the IP and corresponding subdomain information by changing the DNS records of your domain.

Part 1: Preparing your systems for Kubernetes cluster deployment Test the cluster by creating a test pod.Enable and start the kubelet and docker service.Install kubelet, kubeadm, kubectl and docker.The second part is the actual Kubernetes cluster deployment and it consists of the following steps: Configure hostnames correctly on all the hosts.The first part is basically prerequisite and deals with getting your machines ready by doing the following things: The tutorial is divided into two main parts. I am going to use this simple cluster of one master/control node and two worker nodes: Except for the installation commands, rest of the steps should be applicable to all. I have used CentOS Linux in the examples but you should be able to use any other Linux distributions. Production ready? Yes, the examples use a sample domain so if you own a domain, you may configure it on public facing infrastructure. This is a step-by-step tutorial to show you how to deploy a production-ready Kubernetes cluster. I hope you are acquainted with the basic Kubernetes terms like node, service, cluster because I am not going to explain those things here.
