MicroK8s est un outil permettant de deployer ultra facilement un cluster Kubernetes sur n'importe quel distribution linux compatible avec Snap .
Pour installer Microk8s il vous faut un systeme d'exploitation linux avec le paquet snapd d'installé.
Pour ma part j'ai réaliser cette installation sur Ubuntu Server 24.04, j'ai réalisé un post pour l'installation de snap que vous retrouverez via ce lien
Executer cette commande dans un terminal:
snap install microk8s --classicMicroK8s est maintenant installé, vous pouvez interrogé votre cluster kubernetes (qui pour l'instant n'est composé que d'un noeud) a l'aide de cette commande:
microk8s.kubectl get all --all-namespace -o widece qui vous affichera le contenu de votre cluster.
MicroK8s possède plusieurs options vous permettant notamment d'activer/désactiver des plugins vous permettant de deployer en une commande des foncionnalité suplémentaire a votre cluster comme le dashboard accessible depuis un navigateur, voici la commande:
microk8s enable dashboardpuis cette commande pour le rendre accessible a la demande:
microk8s dashboard-proxyChecking if Dashboard is running.

Dans votre navigateur mettez l'adresse ip correspondant a votre serveur/VM : https://<ip du serveur>:10443
Saisissez le token qui a été généré précédement dans votre terminal et cliquer sur connexion:
Vous voila connecté au Dashboard de votre cluster kubernetes microk8s.
