kubeadm + calico 3.6 单节点永远未准备好

Question

我在 Ubuntu 的存储库 (1.13.4) 和 calico 3.6 上使用 Ubuntu bionic (18.04) 和最新版本的 kubeadm，遵循 "Installing with the Kubernetes API datastore—50 nodes or less" 的文档（ https://docs.projectcalico.org/v3.6/getting-started/kubernetes/installation/calico).

开始于：

sudo kubeadm init --pod-network-cidr=192.168.0.0/16

但是当我应用 calico.yaml 时，我的节点遇到了以下情况：

Conditions: Type Status LastHeartbeatTime
LastTransitionTime Reason Message ---- ------ ----------------- ------------------ ------ ------- MemoryPressure False Mon, 15 Apr 2019 20:24:43 -0300 Mon, 15 Apr 2019 20:21:20 -0300 KubeletHasSufficientMemory kubelet has sufficient memory available DiskPressure False Mon, 15 Apr 2019 20:24:43 -0300 Mon, 15 Apr 2019 20:21:20 -0300

runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

当我看到系统 pods (kubectl get pods -n kube-system) 我得到：

NAME                                       READY   STATUS     RESTARTS   AGE

kube-scheduler-cherokee                    1/1     Running    0          44s

这可能是错误还是缺少某些内容？

尝试删除主节点上的污点，kubectl taint nodes --all node-role.kubernetes.io/master-。

参考这里，https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/#control-plane-node-isolation
