Preparing Microk8s

About

This guide will walk you through setting up your infrastructure, whether it is baremetal or a virtual machine.

Getting Started

We will start by setting up and preparing Microk8s on your system

Installing Microk8s

Microk8s can be installed using snap, it usually comes preinstalled on Ubuntu Server. If you don’t have it installed please refer to this guide

To install Microk8s, from your terminal run:

Terminal window
sudo snap install microk8s --classic --channel=1.28

Join the group of microk8s to be able to run microk8s commands

Terminal window
sudo usermod -a -G microk8s $USER && sudo chown -f -R $USER ~/.kube

MicroK8s uses a namespaced kubectl command to prevent conflicts with any existing installs of kubectl. If you don’t have an existing install, it is easier to add an alias (append to ~/.bash_aliases) like this:

Terminal window
alias kubectl='microk8s kubectl'

Enabling Addons

There are few addons that are required before we can start provisioning our services, the list of addons is:

  • cert-manager
  • community
    • nfs
  • dns
  • ha-cluster
  • helm3
  • ingress
  • metrics-server

To enable addons run the following:

Terminal window
microk8s.enable cert-manager community dns ha-cluster helm3 ingress metrics-server

Enabling NFS on all Nodes

Before we can enable the NFS addon we need to make sure NFS is supported on all nodes. To do so install nfs-common package

Terminal window
sudo apt install -y nfs-common

After the command completes, enable nfs addon by running the following

Terminal window
microk8s.enable nfs

That’s it for Microk8s. You are now ready to continue installing other requirements!
