I am trying to create a cron job in openshift and having trouble doing this with oc so I am looking for alternatives.
I have already tried: "oc run cron --image={imagename} \ --dry-run=false" This created another resource. There was no parameter to create a cron job
oc stands for openshift client which is a wrapper created on top of kubectl. It is created to communicate with openshift api server. It supports all operations that are provided by kubectl and others that are specific to OpenShift like operations on templates, builds, build and development config, image stream etc
There's already a good answer on how the two platforms overlap. You mentioned there was no parameter to create a cronjob. You can do that with oc through the following (resource):
oc run pi --image=perl --schedule='*/1 * * * *' \
--restart=OnFailure --labels parent="cronjobpi" \
--command -- perl -Mbignum=bpi -wle 'print bpi(2000)'Or you can do it through a yaml file like the following:
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: hello
spec:
schedule: "*/1 * * * *"
jobTemplate:
spec:
template:
spec:
containers:
- name: hello
image: busybox
args:
- /bin/sh
- -c
- date; echo Hello from the Kubernetes cluster
restartPolicy: OnFailureAnd then run:
oc create -f cronjob.yaml -n default
