I have in this repo k8 installation process on Ubuntu 20.04 Servers

Kubernetes Installation

I wish for this repo to help someone out there who is struggling with deploying k8 on an on-prem cluster.

These are some of the things you should know.

For administration:

• Install the lens application: it makes life easy
• Create a tunnel into the server and connect to your control place port

Lens link: https://k8slens.dev/

In order to connect lens to your cluster, you need to download your config file. Depending on which OS you use, in your home directory create a .kube folder and put that file there. Make sure if its a remote server its using a public IP and an open port on the network.

ssh -fNL <port>:x.x.x.x:<port> <server credentials> e.g [email protected]

On your local machine check the tunnel like this

sudo netstat -nltp | grep <port>

Note:

• K8 does not come preinstalled with network ability or ability to mount volumes, this has to be done manually by the k8 admin.

Follow this process:

Server:

• Install docker
• Install kubectl, kubeadm, kubelet and containerd
• Install flannel for the network of the pods
• Install nfs server for dynamic provisioning of volume.

Client

• Install docker
• Install kubectl, kubeadm, kubelet
• Install nfs-common to helm mount the folders on the master

For my use case I employed flannel for my network and not calico because I honestly could not figure out the way to install the later, but I am willing to learn more.
