image - Kubernetes kubectl 设置镜像部署无法--记录历史记录？

Question

根据用户指南，应该可以update a deployment's image使用 kubectl set/edit 仍然得到有意义的 history .

但是我收到了一些错误，并且没有有意义的历史记录，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
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 again

$ kb rollout history deployment/nginx
deployments "nginx":
REVISION  CHANGE-CAUSE

谢谢!

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。这意味着当 kubectl 更新部署更改历史记录时，部署对象会被修改(很可能由服务器修改)。 kubectl set image 目前不会为您重试冲突时的更改历史记录更新。

我已提交 fix以减轻这种情况。
