[英]Kubernetes Run job using CronJob
Is there a way through which I can run an existing Job using CronJob resource. 有没有一种方法可以使用CronJob资源运行现有的Job。 In CronJob Spec template can we apply a selector using labels.
在CronJob Spec模板中,我们可以使用标签应用选择器。 Something like this:
像这样:
Job Spec: ( Link to job docs ) 职位规格:( 链接到职位文档 )
apiVersion: batch/v1
kind: Job
label:
name: pi
spec:
template:
spec:
containers:
- name: pi
image: perl
command: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
restartPolicy: Never
backoffLimit: 4
Cron Spec: Cron规格:
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: pi-cron
spec:
schedule: "*/1 * * * *"
jobTemplate:
spec:
labelSelector:
name: pi # refer to the job created above
I came across this. 我碰到了这个。 I want to try inverse of this.
我想尝试与此相反。 Create-Job-From-Cronjob
创建-工作-从-的cronjob
No, you can not do this in the way you want. 不,您无法按照自己的方式进行操作。
kubectl
only allows you to create jobs based on cronjob, but not vise-versa. kubectl
仅允许您基于cronjob创建作业,反之亦然。
kubectl create job NAME [--image=image --from=cronjob/name] -- [COMMAND] [args...] [flags] [options]
