Introduction

In this documentation we will see how to deploy and administer a kubernetes cluster with the microk8s solution.
The advantage of the latter is that it is an all-in-one solution that makes installation and administration of the solution much easier.

If you want to install kubernetes "directly" without this solution, you can see our FAQ suivante.

Setting up a cluster of this type requires at least three nodes, our example described in this page uses four that we will name here:

• microk8stest01
• microk8stest02
• microk8stest03

Type of equipment for this type of configuration

This type of configuration is feasible on all of Ikoula's solutions, whether it be:

• The dedicated solutions,
• The Flex virtual solutions,

If your need is to run microservices or a cluster with a large number of nodes, the solution Micro Server Raspberry PI is also possible.

Procedures

The whole procedure below is done on an Ubuntu 20.04 system.

===Installation== = 

The installation of microk8s is very simple and is done as follows (add sudo su the command is not done as root):

snap install microk8s --classic

The installation and configuration will then be done automatically (about 2-3 minutes) and then provide the following output:

===Setting up the cluster== = 

Setting up the cluster is also as simple as this:

• Run the following command on one of the nodes (here 01):

microk8s add-node

You must then copy the command provided (if you have several IPs/networks, select the one allowing your servers to communicate with each other).
Then execute this command on your second server:

Once the operation is completed for the second server, you must do the same operation for the third server (from the beginning in order to generate a new command via the add-node).

===Checking the state of the cluster== = 

It is possible to check the status of the microk8s cluster via the command:

microk8s status --wait-ready

If everything is OK, you should get the following result:

===Remove a node from the cluster == = 

Removing a node from the cluster is done via the command:

microk8s leave

===Activation of the addons integrated in microk8s == = 

The basic microk8s contains the following addons:

You can install / activate an addon simply via the command:

microk8s enable NOM_DE_LADDON
