kube-apiserver pod 一直处于 CreateContainerError 状态
kube-apiserver pod sticks in the CreateContainerError status
我bootstrap一个使用kubeadm的kubernetes集群。在几个月不活动之后，当我得到 运行ning pods 时，我意识到 kube-apiserver 卡在了 CreatecontainerError!

我删除了这个 pod 以重新启动它，但仍然出现同样的问题。

如果需要任何其他信息，请告诉我。
如何正确地运行？
此问题由来自 docker 守护程序的错误消息解释：
message: 'Error response from daemon: Conflict. The container name
"/k8s_kube-apiserver_kube-apiserver-master_kube-system_ce0f74ad5fcbf28c940c111df265f4c8_24"
is already in use by container 14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530.
You have to remove (or rename) that container to be able to reuse that name.'
reason: CreateContainerError
列出所有容器使用：
docker ps -a
您应该能够在列表中找到具有以下名称的容器：
/k8s_kube-apiserver_kube-apiserver-master_kube-system_ce0f74ad5fcbf28c940c111df265f4c8_24
或编号：
14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530
那你可以试试运行删除:
docker rm "/k8s_kube-apiserver_kube-apiserver-master_kube-system_ce0f74ad5fcbf28c940c111df265f4c8_24"
或通过提供其 ID：
docker rm 14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530
如果删除还是有问题，加-f标志强制删除：
docker rm -f 14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530
完成后，您可以尝试删除 kube-apiserver-master pod，以便重新创建它。

如何正确地运行？
此问题由来自 docker 守护程序的错误消息解释：
message: 'Error response from daemon: Conflict. The container name "/k8s_kube-apiserver_kube-apiserver-master_kube-system_ce0f74ad5fcbf28c940c111df265f4c8_24" is already in use by container 14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530. You have to remove (or rename) that container to be able to reuse that name.' reason: CreateContainerError
列出所有容器使用：
docker ps -a
您应该能够在列表中找到具有以下名称的容器：
/k8s_kube-apiserver_kube-apiserver-master_kube-system_ce0f74ad5fcbf28c940c111df265f4c8_24
或编号：
14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530
那你可以试试运行删除:
docker rm "/k8s_kube-apiserver_kube-apiserver-master_kube-system_ce0f74ad5fcbf28c940c111df265f4c8_24"
或通过提供其 ID：
docker rm 14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530
如果删除还是有问题，加-f标志强制删除：
docker rm -f 14935b714aee924aa42295fa5d252c760264d24ee63ea74e67092ccc3fb2b530
完成后，您可以尝试删除 kube-apiserver-master pod，以便重新创建它。
