k3s 创建 pod 沙盒失败

报错信息：Warning FailedCreatePodSandBox 23s (x4 over 28s) kubelet (combined from similar events): Failed to create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container “bc0103bd0b9027f30b605637553f385b7d5872efe355be86d9926f4343ed3e5f” network for pod “coredns-56f6fc8fd7-rwk2z”: networkPlugin cni failed to set up pod “coredns-56f6fc8fd7-rwk2z_kube-system” network: CNI failed to retrieve network namespace path: cannot find network namespace for the terminated container “bc0103bd0b9027f30b605637553f385b7d5872efe355be86d9926f4343ed3e5f”
环境：银河麒麟V10SP3
情况：安装 k3s 完成后，所有 pod 都无法启动，都是报这个错，看着是 CNI 的问题，但其实不是，网上搜的办法资源配额不管用，最后发现其实是 docker 的问题，麒麟环境自带的 podman 会导致 docker 的容器无法创建，知道了原因 ，那么解决就很简单了
解决方案：yum uninstall podman
