I created a CronJob resource in kubernetes.
I want to check the logs to validate that my crons are run. But not able to find any way to do that. I have gone through the commands but looks like all are for pod resource type.
Also tried following
$ kubectl logs cronjob/<resource_name>
error: cannot get the logs from *v1beta1.CronJob: selector for *v1beta1.CronJob not implementedQuestion 1) How to check logs of CronJob Resource type?
2) If i want this resource to be in specific namespace, how to implement that same?
Thanks in advance
You need to check the logs of the pods which are created by the cronjob. The pods will be in completed state but you can check logs.
# here you can get the pod_name from the stdout of the cmd `kubectl get pods`
$ kubectl logs -f -n default <pod_name>For creating a cronjob in a namespace just add namespace in metadata section. The pods will created in that namespace.
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: hello
namespace: default
spec:
schedule: "*/1 * * * *"
jobTemplate:
spec:
template:
spec:
containers:
- name: hello
image: busybox
args:
- /bin/sh
- -c
- date; echo Hello from the Kubernetes cluster
restartPolicy: OnFailureIdeally you should be sending the logs to a log aggregator system such as ELK or Splunk.
