Openshift en local, Minishift, peut être enrichi avec quelques plugins. Je vous propose de les ajouter. Le plus intéressant est pour moi la console de supervision transverse: le dashboard Kubernetes.
Installation des addons par défaut
- anyuid: Les projets auront les droits d’exécution anyuid par défaut.
- xpaas: Les templates de RedHat sont installés.
- admin-user: L’administrateur du cluster est défini.

Installation des addons complémentaires de Jorge Moralespou
Jorge propose quelques addons sympathiques sur GitHub dont la console Kubernetes. Elle va nous permettre de suivre les ressources matérielles de manière transverse, en plus de celle de OpenShift.
