CronJobs-Scalable Open Financial Architecture(SOFAStack)-阿里云帮助中心

CronJobs are used to create periodic and repetitive tasks, such as DBS or sending emails. Job is responsible for batch processing of short one-time tasks, that is, tasks that are executed only once, while CronJob adds time scheduling based on Job, that is, to run a specified job within a specified time period. This topic describes how to create CronJobs in the console and other common operations.

Note

CronJob is a native concept of Kubernetes. For more information, see Kubernetes documentation.

Create CronJobs

Go to the Cluster Details page, click the Workloads tab.
In the left-side navigation pane, choose CronJobs and click Create CronJobs.

In the dialog box that appears, enter the YAML content and click Submit.

YAML sample is as follows:

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: hello
spec:
  jobTemplate:
    spec:
      template:
        spec:
          containers:
            - command:
                - /bin/sh
                - '-c'
                - date; echo Hello from the Kubernetes cluster
              image: 'registry-vpc.cn-hangzhou.aliyuncs.com/sofa-samples/nginx:latest'
              imagePullPolicy: IfNotPresent
              name: hello
          restartPolicy: Never
  schedule: '* */1 * * *'

The following table describes the parameters.

Parameters	Description
kind	Identifies the CronJob resource type.
metadata	The basic information about the CronJob, such as the name of the CronJob.
spec.schedule	The cron policy that is executed by the CronJob. That is, the specified task running cycle. The format is the same as Cron schedule. `# Format description # -- Minutes (0 - 59) # \| -- Hours (0 - 23) # \| \| -- Day (1 - 31) # \| \| \| -- Month (1 - 12) # \| \| \| \| -- Week (0 - 6) # \| \| \| \| \| # * * * * *`
spec.jobTemplate	Job template for cron execution. That is, specify the task to be run, in the same format as the Job patterns.

Execution Results

The created CronJobs appears on the list page. When the CronJob is executed, a job is created at the specified time, and then the job creates a pod.
