Kubernetes n'a pas réussi à extraire l'image k8s.gcr.io

J'essaie d'installer Kubernetes sur ma machine CentOS, lorsque j'initialise le cluster, j'ai l'erreur suivante.

Je précise que je suis derrière un proxy d'entreprise. Je l'ai déjà configuré pour Docker dans le répertoire: /etc/systemd/system/docker.service.d/http-proxy.conf Docker fonctionne bien.

Peu importe à quel point je regarde, je ne trouve pas de solution à ce problème.

Merci de votre aide.
