Make sure that each firewall-cmd command, returns a success. Set the following firewall rules on ports. # sed -i -follow-symlinks 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux

Next, disable SElinux and update your firewall rules. You can ping worker-node-1 and worker-node-2 to test if your updated hostfile is fine using ping command. On your master node, set the hostname and if you don’t have a DNS server, then also update your /etc/hosts file. Step 1: Prepare Hostname, Firewall and SELinux The following steps will run on the Master-Node. For this installation, we will use docker as it is the most popular. Our 3-node cluster will look something like this: Kubernetes Cluster Diagram Installation of Kubernetes Cluster on Master-Nodeįor Kubernetes to work, you will need a containerization engine.

Recommended Read: How to Install a Kubernetes Cluster on CentOS 8įor this tutorial, we will walk-through a multi-node Kubernetes cluster installation on CentOS 7 Linux. For this, you can use Minikube, which is a tool that runs a single-node Kubernetes cluster in a virtual machine on your node. It’s also important to mention that you can also deploy a single-node Kubernetes cluster which is generally recommended for very light, non-production workloads. The worker-nodes are then managed from the master node, thus ensuring that the cluster is managed from a central point.

It can manage and orchestrate not just docker runtimes but also Containers and Rkt runtimes.Ī typical Kubernetes cluster would generally have a master node and several worker-nodes or Minions. Donated by Google to the Opensource community, Kubernetes has now become the container management tool of choice.
