kubernetes - Kubernetes 未在 Fedora Server 33 上初始化控制平面

Question

编辑：所以我一直在努力确保 IP 流量可以从 docker 流向 kubernetes（参考https://fedoramagazine.org/docker-and-fedora-32/），然后我的journalctl 错误。日志太大，无法发布到 stackoverflow，所以这里是https://creedence.mchambersradio.com/journalctl_kubelet.txt

我正在尝试在 Fedora 33 VM 上运行一个基本的 Kubernetes 集群，其中我总共有 3 个节点，我计划将其放入一个集群中进行一些实验。我安装了基本的 Fedora Server 33，删除了 zram 交换并安装了 kubernetes 和 kubeadm。我已经在 firewalld 中为 kubernetes 开放了所有推荐的端口，并且我已经设置了 SELinux Policy 以允许 kubernetes 具有访问权限（并且在我让 kubernetes 运行之前让 SELinux 处于 Permissive 中，然后我将验证我可以运行它强制执行之后）。

我相当肯定我正在做一些愚蠢的事情，这在手册中很明显，但我只是没有找到它。如果答案是手册的链接，我不会生气，但如果可能的话，您能否将我链接到手册中的正确位置。谢谢

当我打电话

sudo kubeadm init --config kubeadm-config.yaml

我明白了

        Unfortunately, an error has occurred:
                timed out waiting for the condition

        This error is likely caused by:
                - The kubelet is not running
                - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

        If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
                - 'systemctl status kubelet'
                - 'journalctl -xeu kubelet'

        Additionally, a control plane component may have crashed or exited when started by the container runtime.
        To troubleshoot, list all containers using your preferred container runtimes CLI.

        Here is one example how you may list all Kubernetes containers running in docker:
                - 'docker ps -a | grep kube | grep -v pause'
                Once you have found the failing container, you can inspect its logs with:
                - 'docker logs CONTAINERID'

error execution phase wait-control-plane: couldn't initialize a Kubernetes cluster
To see the stack trace of this error execute with --v=5 or higher

作为修复尝试关闭交换：

$ sudo swapoff -a
$ sudo sed -i '/ swap / s/^/#/' /etc/fstab

然后重新启动您的虚拟机。然后执行命令：

$ kubeadm reset
$ kubeadm init --ignore-preflight-errors all

请参阅：kubeadm-timeout、kubeadm-swapoff。

尝试卸载负责创建交换的服务

sudo dnf remove zram-generator-defaults

这应该可以解决您的问题。
