metadata.finalizers[0]: 无效值: "foregroundDeletion": 名称既不是标准终结器名称也不是完全限定的

Question

我们有一个完整的集群运行在生产中，它突然停止工作并出现以下错误：

The Deployment "authapi" is invalid: metadata.finalizers[0]: Invalid value: "foregroundDeletion": name is neither a standard

finalizer name nor is it fully qualified

我当前的集群版本是：

Client Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.3", GitCommit:"2c2fe6e8278a5db2d15a013987b53968c743f2a1", GitTreeState:"clean", BuildDate:"2017-08-03T07:00:21Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.6", GitCommit:"7fa1c1756d8bc963f1a389f4a6937dc71f08ada2", GitTreeState:"clean", BuildDate:"2017-06-16T18:21:54Z", GoVersion:"go1.7.6", Compiler:"gc", Platform:"linux/amd64"}

另一方面，我们也无法部署。 kubectl 尝试部署时出现以下消息：

   W1127 15:28:32.999978 42625 factory_object_mapping.go:423] Failed to download OpenAPI (the server could not find the requested
resource), falling back to swagger The Deployment "authapi" is invalid: metadata.finalizers[0]: Invalid value: "foregroundDeletion": name is neither a standard finalizer name nor is it fully qualified /home/builduser/myagent/_work/_temp/kubectlTask/1511796511792/kubectl failed with return code: 1

YAML定义如下：

对此有任何帮助吗？

Answer 1

我通过以下命令解决了问题运行：

kubectl delete deployments/authapi --namespace=production --force

Answer 2

这是一个错误，已在 1.6.7+ 中修复

https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.6.md/#v167

Fix Invalid value: "foregroundDeletion" error when attempting to delete a resource. (#46500, @tnozicka)

Answer 3

在集群运行版本 1.6.0 上尝试升级集群中的服务运行时遇到此问题。我无法立即升级 kubernetes 集群（以修复错误）。

检查部署中的 pods 并注意到其中一个卡在 "Terminating" 状态。

我描述了 pod 以获取它运行上的 kubernetes 节点，进入该节点，在 kubelet 日志上出现此错误

kuberuntime_manager.go:858] getPodContainerStatuses for pod "_default(781d0645-23d3-11e8-bcca-00505690014f)" failed: rpc error: code = 2 desc = unable to inspect docker image

重新启动 Docker 和节点上的 kubelet，pod 现在已经消失并且可以毫无问题地更新服务。
