Kubernetes kubectl设置图像部署无法 - 记录历史记录？

Question

根据用户指南,应该可以更新部署的映像,kubectl set/edit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

这是由于我们更新部署的注释（用于记录其更改历史记录）时发生更新冲突。这意味着部署对象被修改（很可能是由服务器）kubectl这意味着部署对象在更新部署更改历史记录kubectl set image目前不会为您重试更改冲突历史记录更新。

我已经提交了修复程序来缓解这种情况。
