INSTALL KUBERNETES CLUSTER ON CENTOS INSTALL
In my case I used CentOS 7.5 Minimal(CentOS-7-x86_64-Minimal-1804.iso), install that on your bare-metal server. The first steps is to Download a CentOS image. CentOS(1804) as the Ber-Metal and Kubernetes VM’s.Oracle VirtualBox to virtualize the Master and Worker nodes.Hostname / IP Address diagram used in the below configuration To make it easier to understand the Kubernetes configuration, lets start first with a the Hostname / IP Address digram described below. This is Part 1 – Installing and configuring kubernetes – Initial setup – bear-metal installation, configuration. You can generate your own configuration in minutes by using the generator, available on my GitHub repository by going here, you can also just use the ready examples files available here Version 0.7 just became available of the Kubernetes generator, supporting kubernetes version v.1.13.x+, RBAC, Auto Bootstraping, and more.

Get going in minutes with a full Kubernetes cluster by using the free Kubernetes generator on my GitHub repository.

Part 4: Installing and configuring kubernetes manifest and kubelet service.Part 3: Installing and configuring Flanneld, CNI plugin and Docker.Part 1: Initial setup – bear-metal installation, configuration.Note: With the recent Kubernetes version(s) it is possible to install a multi-master cluster by using the kubeadm utility, however its still in beta and requires a few workarounds to make it work.
INSTALL KUBERNETES CLUSTER ON CENTOS HOW TO
in the next few articles, I will be showing you how to configure a Kubernetes cluster manually without using the kubeadm utility. which is not officially support for a multi-master configuration. While there are many places describing the Kubernetes installation process, they mostly use the kubeadm utility. Installing a 3 node(master) Kubernetes cluster on CentOS 7.5īelow I am going to show you how install, configure a 3 node multi-master Kubernetes 1.11 Cluster without using kubeadm, in addition I will also show you how to install/configure 2 worker nodes.
