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中有一个滚动更新(自动没有停机)，但是没有滚动重启，至少我找不到.我们必须更改部署Yaml.有没有办法使滚动重启"，最好不更改部署yaml?

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?

推荐答案

在kubernetes 1.15之前，答案是否定的.但是有一种解决方案，可以使用虚拟注释对部署规范进行修补:

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'`\"}}}}}"

从kubernetes 1.15开始，您可以使用:

As of kubernetes 1.15 you can use:

kubectl rollout restart deployment your_deployment_name

CLI的改进

• 创建了一个新的kubectl rollout restart命令，该命令可滚动重启部署.
• kubectl rollout restart现在可用于DaemonSet和StatefulSets

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