如何在不更改 kubernetes 中的部署 yaml 的情况下滚动重启 pod? [英] How to rolling restart pods without changing deployment yaml in kubernetes?

问题描述

在 kubernetes 中有滚动更新(自动无需停机)但没有滚动重启，至少我找不到.我们必须更改部署 yaml.有没有办法让滚动重启"，最好不改变部署yaml?

解决方案

在 kubernetes 1.15 之前，答案是否定的.但是有一种使用虚拟注释修补部署规范的解决方法:

kubectl 补丁部署 web -p "{"spec":{"template":{"metadata":{"annotations":{"date":"`date +'%s'`"}}}}}"

从 kubernetes 1.15 开始，您可以使用:

kubectl rollout restart deployment your_deployment_name

CLI 改进

• 创建了一个新的 kubectl rollout restart 命令，用于滚动重启部署.
• kubectl rollout restart 现在适用于 DaemonSets 和 StatefulSets

In kubernetes there is a rolling update (automatically without downtime) but there is not a rolling restart, at least i could not find. We have to change deployment yaml. Is there a way to make rolling "restart", preferably without changing deployment yaml?

解决方案

Before kubernetes 1.15 the answer is no. But there is a workaround of patching deployment spec with a dummy annotation:

kubectl patch deployment web -p 
  "{"spec":{"template":{"metadata":{"annotations":{"date":"`date +'%s'`"}}}}}"

As of kubernetes 1.15 you can use:

kubectl rollout restart deployment your_deployment_name

CLI Improvements

• Created a new kubectl rollout restart command that does a rolling restart of a deployment.
• kubectl rollout restart now works for DaemonSets and StatefulSets
