在 kubernetes 的服务器上空运行时出错

Question

与：

kubectl apply -f web.yaml --server-dry-run --validate=false -o yaml

我收到一个错误：

Error: unknown flag: --server-dry-run
See 'kubectl apply --help' for usage.

甚至：

kubectl apply -f web.yaml --dry-run=server --validate=false -o yaml

我收到另一个错误：

Warning: resource deployments/web is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.
Error from server (Conflict): error when applying patch:

我该怎么办？

我正在使用 docker-desktop，我的 kubectl 版本是：

Client Version: version.Info{Major:"1", Minor:"22", GitVersion:"v1.22.4", GitCommit:"b695d79d4f967c403a96986f1750a35eb75e75f1", GitTreeState:"clean", BuildDate:"2021-11-17T15:48:33Z", GoVersion:"go1.16.10", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"22", GitVersion:"v1.22.4", GitCommit:"b695d79d4f967c403a96986f1750a35eb75e75f1", GitTreeState:"clean", BuildDate:"2021-11-17T15:42:41Z", GoVersion:"go1.16.10", Compiler:"gc", Platform:"linux/amd64"}

我的集群版本是1.22.4

我收到一个错误：

Error: unknown flag: --server-dry-run
See 'kubectl apply --help' for usage.

没错。此标志已弃用。您需要使用--dry-run=server 标志。更多请看at this site。

至于第二个问题，这在k8s方面似乎是正确的。您可以找到explanation here。如果您想解决您的问题，您需要删除字段creationTimestamp。在this question 中有很好的解释。
