我一直在阅读 Alan Hohn 的《Kubernetes 之书》，并决定尝试让最后一章中描述的应用程序与 Flannel CNI 而不是 Calico 一起工作，这是应用程序默认使用的。但是 Longhorn 存储系统拒绝与 Flannel 一起工作。只有一个longhorn-manager和longhorn-csi-plugin pod 启动（longhorn-manager-c46fd和longhorn-csi-plugin-nzw5v），node02在我提供的示例中，两者都在。longhorn -csi-plugin pod 正在尝试连接到主机系统上名为/csi/csi.sock（的套接字/var/lib/kubelet/plugins/driver.longhorn.io/csi.sock），该套接字仅在上可用host02。
