Creating CronJobs

A CronJob is a one-off task that runs at a specified time or a task that runs periodically. It corresponds to the CronJob in Kubernetes. You can create a CronJob in a cluster by using an image.

Prerequisites

A container image has been created. You can directly use an image from a third-party container registry, or upload an image to the Container Registry (CR) service. To upload an image to CR, see Pushing and pulling images.

Creating DaemonSets on the console

In the left navigation bar, click Cluster.

Click Workload > CronJob in the left navigation bar. On the page that appears, click Create CronJob.

Configure CronJob information. For parameter details, see Workload configurations.

Click Confirm in the lower-right corner of the page.

Creating CronJobs by using kubectl

tip

Before you start creating a CronJob by using kubectl, make sure that the following conditions are met:

The kubectl tool has been installed on your on-premises computer. For details, see Installing and configuring kubectl.

The target cluster has been connected through kubectl. For details, see Connecting to clusters.

Create the YAML file of the workload. The code of the cronjob-demo.yaml sample file is as follows:

apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: cronjob-demo # The CronJob name.
namespace: default # The namespace to which the CronJob belongs.
spec:
schedule: "*/1 * * * *" # The execution time of the CronJob.
jobTemplate:
spec:
template:
spec:
containers:
- name: hello # The name of the container in the CronJob.
image: busybox # The container image.
command: # The command executed in the container.
- /bin/sh
- -c
- date; echo Hello from the Kubernetes cluster
resources:
requests: # Specify CPU and memory requests for the container.
cpu: "500m"
memory: "1024Mi"
limits: # The resource quotas, such as the CPU limit, memory limit, and number of RDMA cards.
cpu: "1"
memory: "2Gi"
vke.volcengine.com/rdma: 2
restartPolicy: OnFailure # The restart policy when the Job fails in the container. Valid values: Never and OnFailure.

Run the following command to create the workload.

kubectl apply -f cronjob-demo.yaml

Operation result

After you create the CronJob, you can view the status of the workload on the Workload > CronJob page. You can click the button in the Actions column to manage the created CronJob. For more operations, see Managing workloads.
