Azure k8s windows cluster, Erreur interne: Statistiques manquantes pour le conteneur racine

Question

J'ai créé un cluster Windows K8s (1 maître et 1 nœud). Le tableau de bord kubernetes montre les deux nœuds. Le tableau de bord ne montre que l'utilisation des ressources du maître.

En inspectant les journaux de heapster du tableau de bord, je vois l'erreur suivante:

... E0331 18:17:05.029078  1 summary.go:97] error while getting metrics summary from Kubelet a67a6acs9000(10.240.0.4:10255): request failed - "500 Internal Server Error", response: "Internal Error: Missing stats for root container" 

journaux Kubulet sur le nœud fenêtres ont l'erreur suivante:

La valeur par défaut K8S configuration du cluster sur ACS utilise Heapster v1.2.0 et j'ai remarqué qu'une nouvelle version v1.3.0 est disponible. J'ai donc mis à jour Heapster, mais les erreurs existent toujours.

Answer 1

Merci pour ce rapport. ACS Windows Kubernetes est encore en cours de développement et il doit y avoir un scrub de tous les problèmes communs. J'ai la tâche suivante sur Kubernetes pour suivre ceci: https://github.com/kubernetes/kubernetes/issues/43993.
