We typically create a k8s job like this:
kubectl apply -f some-job-config.yaml
This is nice enough, but sometimes we need to launch a job that is already defined in a cronjob config. So rather than copying and pasting the applicable cronjob config into a new file, we can simply use the
--from option with
kubectl create job.
kubectl create job --from=cronjob/<cronjob-name> <job-name>
The name of the job needs to be unique, and the cronjob name can be found using:
kubectl get cronjob
Helpful note: It's wise to come up with a job naming convention and stick with it. As an example, we could use the name of the cronjob and append the timestamp.
