Kubernetes OpenStack集成

Question

試圖使集成工作，但有一些問題。 當--cloudprovider=openstack ， kube-apiserver此消息后， kube-apiserver立即崩潰。所有需要的配置都通過cloud.conf提供，並通過--cloudconfig=/etc/cloud.conf 。 有人在這種設置上有成功嗎？

錯誤信息：

Answer 1

好的， region為強制選項。 當它為空時，代碼將失敗。 即使您的OpenStack不使用區域，也必須指定它。 最大的問題是代碼本身不會檢查用戶指定的參數，因此無法告知您您在做什么錯。

Answer 2

您可以在此處粘貼cloud.conf嗎？ 看來您的openstack雲沒有實例化。
