Kubernetes kubectl设置映像部署无法--记录历史记录

Question

根据用户指南，应该可以使用kubectl set/edit更新部署的映像，并且仍然可以获得有意义的历史记录。

然而，我得到了一些错误，没有有意义的历史，这可能是一个错误吗？

$ kubectl create -f kubernetes/deployment.yml --record
deployment "nginx" created
$ kubectl set image deployment/nginx nginx=nginx:0.2.0
deployment "nginx" image updated
changes to deployments/nginx can't be recorded: Operation cannot be fulfilled on deployments.extensions "nginx": the object has been modified; please apply your changes to the latest version and try againc
$ kubectl set image deployment/nginx nginx=nginx:0.2.1

谢谢！

这是由于我们在更新部署的注释（用于记录其更改历史）时发生更新冲突。这意味着当kubectl更新部署更改历史记录时，部署对象会被修改（很可能是由服务器修改）。kubectl set image当前不会为您重试冲突时的更改历史记录更新。

我已经提交了一份解决方案来缓解这种情况。
