我有三个节点集群,不知何故,它最终处于 pod 始终处于 ContainerCreating 状态的情况。

NAME                          READY     STATUS              RESTARTS   AGE
i-have-no-sa                  0/1       ContainerCreating   0          7h
prometheus-5464597859-5kfkd   0/1       ContainerCreating   0          7m
test-site-5768cf4dd5-zdjms    0/1       ContainerCreating   0          8m

如果我查看任何这些 pod 的日志,我可以看到以下内容

   Normal   SandboxChanged          4m (x7 over 4m)  kubelet, host2 Pod sandbox changed, it will be killed and re-created.
  Warning  FailedCreatePodSandBox  4m (x8 over 4m)  kubelet, host2 Failed create pod sandbox.

我正在使用法兰绒网络,所有的 pod 都在运行

kube-dns-6f4fd4bdf-5d29c                   3/3       Running             0          8h
kube-flannel-ds-74krh                      1/1       Running             0          8h
kube-flannel-ds-f4x2r                      1/1       Running             0          8h
kube-flannel-ds-w8dvf                      1/1       Running             0          8h
kube-proxy-2qz57                           1/1       Running             0          8h
kube-proxy-nnk76                           1/1       Running             0          8h
kube-proxy-wzph7                           1/1       Running             0          8h

在我之前的尝试中,kube-dns pod 也始终处于挂起状态,但现在工作正常。

Kubernetes v1.9.0 on master Kubernetes v1.9.2 on slave1 Kubernetes v1.9.2 on slave2
