Kubernetes kubectl設置圖像部署不能夠 - 記錄歷史？

Question

根據用戶指南，應該有可能update a deployment's image與kubectl set/edit，仍然可以得到一個有意義的history。

但是我得到一些錯誤，而沒有有意義的歷史，這可能是一個錯誤？

$ 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 
1 kubectl create -f kubernetes/deployment.yml --record 
2 kubectl create -f kubernetes/deployment.yml --record 
3 kubectl create -f kubernetes/deployment.yml --record 

$ kubectl version

謝謝！

這是由於更新部署的註釋（用於記錄其更改歷史記錄）時發生更新衝突。這意味着當kubectl更新部署更改歷史記錄時，部署對象被修改（很可能由服務器）。 kubectl set image目前不會在衝突時重試更改歷史記錄更新。

我已經提交了一個fix來減輕這一點。
