我正在嘗試使用 Kubespray 安裝 Kubernetes 叢集。我在腳本運行時收到此錯誤：

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: FileNotFoundError: [Errno 2] No such file or directory: '/lib/modules/5.2.0/modules.builtin'

我使用 Ubuntu 22.04 作為控制平面和工作節點。

你知道我該如何解決這個問題嗎？

我使用這個作業系統：https://src.openvz.org/projects/OVZT/repos/ubuntu-22.04-x86_64-ez/browse

好的。我有同樣的錯誤。

原因是我嘗試透過 kubespray 來安裝 k8sLXD貨櫃。這就是為什麼資料夾 /lib/modules 在 lxd 容器內是空的。

我不知道你的情況，但是：

  • 如果您嘗試在普通的 Linux 主機上安裝 k8s，那麼檔案「modules.builtin」是套件「linux-modules-5.2.0-generic」的一部分
  • 如果您嘗試在 lxd 容器內安裝 k8s，請返回主主機並載入以下核心模組：
    br_netfilter
    ip_vs
    ip_vs_rr
    ip_vs_wrr
    ip_vs_sh
    nf_conntrack

確保每次主機啟動時都加載它們，請使用以下命令

# cat /etc/modules-load.d/modules.conf  | grep -v '#'

br_netfilter
ip_vs
ip_vs_rr
ip_vs_wrr
ip_vs_sh
nf_conntrack

#  systemctl restart systemd-modules-load
#  systemctl status  systemd-modules-load

ansible 中產生錯誤的檔案如下：

$kubespray_folder/kubespray/roles/kubernetes/node/tasks/main.yml

希望它能像對我一樣有所幫助
