Script pour configurer la machine pour gérer le cluster Kubernetes avec Azure Arc

Pour communiquer avec et configurer un cluster Kubernetes avec Azure Arc pour Edge RAG, configurez n’importe quelle machine Windows avec des outils tels qu’Azure CLI, kubectl et Helm. La machine doit être en mesure d’atteindre le cluster Kubernetes.

Exemple de script

Exécutez cet exemple de script pour configurer une machine Windows pour effectuer les tâches suivantes :

  1. Créez un dossier.
  2. Téléchargez Azure CLI, Helm, kubectl et les extensions Azure CLI aksarc et Kubernetes-extension.
  3. Connectez-vous à Azure à l’aide d’Azure CLI avec l’abonnement et l’ID de locataire.
  4. Connectez-vous au cluster Kubernetes avec Azure Arc.
  5. Enregistrez les informations d’identification pour kubectl.
