Kubernetes Cluster Installation

Prerequisities

Action	Notes
Basic CentOS 7 Installation Basic Debian Installation	the kubernetes cluster is based on the standard install of Centos 7 or Debian 10 for all systems/nodes; clusters can have mixed OS among its nodes
Ethernet Device Configuration	for convenience rename network devices to eth* (optional)
CUDA + NVIDIA drivers	if the node has a GPU, install the drivers and libraries
Docker Installation	Docker is required for all nodes (not required for k3s cluster install)
IP Tables config	set up the system config to use IP Tables properly

Kubernetes Cluster

There are multiple ways to deploy a kubernetes cluster. These two have been tried and are (at least somewhat) functional.

kubeadm

Full instructions for creating a cluster using kubeadm are located in the kubernetes documentation: https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/

Kubernetes Controller	install kubernetes cluster controller
Kubernetes Nodes	install kubernetes nodes

k3s

See the K3s - Kubernetes Simplified page for instructions

The Rest of the Stuff

These are the parts of the cluster that may be installed by one of the above methods, but not always.

IP Controller	set up load balancer to assign IP addresses when needed
Metrics Server	install metrics collection for the dashboard
k8dash Dashboard	install the web GUI dashboard<ref>the original/default kubernetes dashboard installation instructions are located at kubernetes Dashboard</ref>
Rook Storage for Kubernetes	dynamic storage provisioning
helm installation	kubernetes package installer

Final Configuration

Now load the rest of the packages for each cluster:

• Production Cluster Configuration
• Development Cluster Configuration
• Test Cluster Configuration
