A job creates one or more pods and ensures that a specified number of them successfully terminate.
For more information about Jobs checkout the Kubernetes User Guide.
In this Tutorial you'll learn how to run a Job in the Cluster.
In this scenario we want to run a batch job of 10 Pods that will calculate something (in our case just sleep), but keeping the maximum number of parallel executions to 3.
Go to the tutorial chart repo and run the
Here is the Job definition:
apiVersion: batch/v1 kind: Job metadata: name: pi spec: completions: 10 parallelism: 3 template: metadata: name: pi spec: containers: - name: pi image: alpine:3.4 command: ["sleep", "5"] restartPolicy: Never
Now go to the Jobs section. You'll see the
pi Job that generates 10 Pods with a maximum of 3 in Running State at each moment.
Once desired number of successful Pods is reached then Job is marked green.
You can now delete the Job.
