Kubernetes Misconfiguration: Missing Kubelet Identity Verification
Abstract
当 Kubernetes API 服务器建立 SSL 连接时,Kubelets 的服务器身份验证将被禁用。
Explanation
Kubernetes API 服务器向 Kubelet 发送指令以创建工作负载、查询 Kubelet 托管资源的状态,并为 Kubelet 提供可选的端口转发服务。默认情况下,API 服务器在建立连接之前不会验证 Kubelet 的服务证书。因此,此连接易受到中间人攻击。
示例 1:以下命令将启动 Kubernetes API 服务器,但未指定根证书捆绑包以使用
示例 1:以下命令将启动 Kubernetes API 服务器,但未指定根证书捆绑包以使用
--kubelet-certificate-authority
标记验证 Kubelet 的服务证书。
