More complex Kubernetes CronJob on Busybox

On the docs said…

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: OnFailure

,but this is my cronjob that can not put into containers.args

wget --proxy off -T60 -q  -O - --header "Host: sample.home.net" http://192.168.1.123/job.php

The solution is just make a simple shell script and add it into configmap

apiVersion: v1
data:
wgetcron.sh: |-
#!/bin/sh
wget --proxy off -T60 -q -O - --header "Host: sample.home.net" http://192.168.1.123/job.php || true
kind: ConfigMap
metadata:
annotations:
name: mycron

Here is my Cronjob

apiVersion: v1

- apiVersion: batch/v1beta1
kind: CronJob

name: wgetcron

Done

Very short and simple notes for CKA/SRE and may not works on your environment.
