Kubernetes使用CronJob运行作业 [英] Kubernetes Run job using CronJob

问题描述

有没有一种方法可以使用CronJob资源运行现有的Job. 在CronJob Spec模板中，我们可以使用标签应用选择器.像这样:

Is there a way through which I can run an existing Job using CronJob resource. In CronJob Spec template can we apply a selector using labels. Something like this:

工作规范:(

Cron Spec:

Cron Spec:

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: pi-cron
spec:
  schedule: "*/1 * * * *"
  jobTemplate:
    spec:
      labelSelector:
        name: pi # refer to the job created above

我碰到了这个.我想尝试与此相反. Create-Job-From-Cronjob

I came across this. I want to try inverse of this. Create-Job-From-Cronjob

推荐答案

不，您不能以所需的方式执行此操作. kubectl仅允许您基于cronjob创建作业，反之亦然.

No, you can not do this in the way you want. kubectl only allows you to create jobs based on cronjob, but not vise-versa.

 kubectl create job NAME [--image=image --from=cronjob/name] -- [COMMAND] [args...] [flags] [options]

现在可用于kubectl create的命令:
