如何安排Pod重新启动 [英] How to schedule pods restart

问题描述

是否可以根据时间自动重启Pod?

Is it possible to restart pods automatically based on the time?

例如，我想每天早上8:00 AM重新启动集群的容器.

For example, I would like to restart the pods of my cluster every morning at 8.00 AM.

推荐答案

有一个特定的资源:这里有个例子:

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: your-cron
spec:
  schedule: "*/20 8-19 * * 1-5"
  concurrencyPolicy: Forbid
  jobTemplate:
    spec:
      template:
        metadata:
          labels:
            app: your-periodic-batch-job
        spec:
          containers:
          - name: my-image
            image: your-image
            imagePullPolicy: IfNotPresent
          restartPolicy: OnFailure

如果要在启动新Pod时替换旧Pod，请

将spec.concurrencyPolicy更改为Replace.使用Forbid，如果旧的Pod仍在运行，则将跳过新的Pod创建.

change spec.concurrencyPolicy to Replace if you want to replace the old pod when starting a new pod. Using Forbid, the new pod creation will be skip if the old pod is still running.
