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:
Job Spec: (Link to job docs)
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: 4Cron Spec:
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: pi-cron
spec:
schedule: "*/1 * * * *"
jobTemplate:
spec:
labelSelector:
name: pi # refer to the job created aboveI came across this. I want to try inverse of this. Create-Job-From-Cronjob
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]Available commands right now for kubectl create:
clusterrole Create a ClusterRole.
clusterrolebinding Create a ClusterRoleBinding for a particular ClusterRole
configmap Create a configmap from a local file, directory or literal value
deployment Create a deployment with the specified name.
job Create a job with the specified name.
namespace Create a namespace with the specified name
poddisruptionbudget Create a pod disruption budget with the specified name.
priorityclass Create a priorityclass with the specified name.
quota Create a quota with the specified name.
role Create a role with single rule.
rolebinding Create a RoleBinding for a particular Role or ClusterRole
secret Create a secret using specified subcommand
service Create a service using specified subcommand.
serviceaccount Create a service account with the specified name
