We will be fetching Kubernetes and docker packages from the repository.

Internet connectivity on all your nodes.

This is not a strict requirement but is largely driven by the needs of the application you intend to run.

It is recommended that your nodes should have at least 2 CPUs with 2GB RAM or more per machine.

Three servers running CentOS 8 – 1 Master Node and 2 Worker Nodes.

In a later article, we will also run through a similar installation, using podman for our containers. Podman promises to offer more flexibility when running on Kubernetes environments, but the jury remains out there.įor this article, we will run through the process of installing Kubernetes on a CentOS 8 platform, running on Docker-CE ( Community Edition). With this move, the Redhat team aims to simplify the process of creating and using containers, without needing special permissions, while at the same time, maintaining compatibility with docker images and operating them without needing a daemon. As a matter of fact, the docker package has now been removed from the default package repository. Starting from CentOS 8 (and by extension RHEL 8), docker has now natively been replaced by podman and buildah which are tools from Redhat.

These changes, mostly revolve around the installation of Docker.

The process of installing a Kubernetes Cluster on CentOS 8 is almost similar to that of CentOS 7 (which you can go through here), but the process here has a few changes.
