无法使用Multus将第二个界面添加到Pod-Minikube

问题描述

我正在尝试使用multus-cni部署具有第二个界面的Pod。但是，当我部署Pod时，我只能看到一个主界面。辅助接口未创建。

我按照快速入门指南中的步骤安装了multus。

环境： Microsoft Windows 10企业版上的minikube v1.12.1 Docker 19.03.12上的Kubernetes v1.18.3

Multus版本 --cni-version = 0.3.1

$ 00-multus.conf

$ 1-k8s.conf

}
},{

},{

}
]
}

$ multus.kubeconfig

    }'
    EOF

解决方法

我安装了新的minikube版本，现在添加辅助接口似乎没问题。

cni kubernetes minikube
