Schedule Cronjobs in Kubernetes

Tasks

Create a cronjob named xfusion.
Set its schedule to something like */7 * * * *. You can set any schedule for now.
Name the container cron-xfusion.
Utilize the httpd image with latest tag (specify as httpd:latest).
Execute the dummy command echo Welcome to xfusioncorp!.
Ensure the restart policy is OnFailure.

Steps

Create a manifest file cronjob.yaml using given details.

 apiVersion: batch/v1
 kind: CronJob
 metadata:
   name: xfusion
 spec:
   schedule: "*/7 * * * *"
   jobTemplate:
     spec:
       template:
         spec:
           restartPolicy: OnFailure
           containers:
             - name: cron-xfusion
               image: httpd:latest
               command: ["echo", "Welcome to xfusioncorp!"]

 cat <<EOF > cronjob.yaml
 apiVersion: batch/v1
 kind: CronJob
 metadata:
   name: xfusion
 spec:
   schedule: "*/7 * * * *"
   jobTemplate:
     spec:
       template:
         spec:
           restartPolicy: OnFailure
           containers:
             - name: cron-xfusion
               image: httpd:latest
               command: ["echo", "Welcome to xfusioncorp!"]
 EOF

Now apply the yaml manifest file.
```
 k apply -f cronjob.yaml
```
- We can also use kubectl apply -f cronjob.yaml too.
Let’s get the result.
```
  k get cronjob -o wide
```
Describe the cronjob now.
```
 k describe cronjob
```
