Job¶
Jobs are a very useful concept in kubernetes deployments. They can be used for add-hoc provisioning tasks, as well as long running processing jobs.
In configuration, they don’t differ much from regular pods, but offer some additional properties.
Delete a Job after its finished¶
You can configure a TTL for the job after it finished its execution successfully.
import * as kplus from 'cdk8s-plus-30';
import { Construct } from 'constructs';
import { App, Chart, ChartProps, Duration } from 'cdk8s';
export class MyChart extends Chart {
constructor(scope: Construct, id: string, props: ChartProps = { }) {
super(scope, id, props);
// let's define a job spec, and set a 1 second TTL.
const job = new kplus.Job(this, 'LoadData', {
ttlAfterFinished: Duration.seconds(1)
});
// now add a container to all the pods created by this job
job.addContainer({
image: 'loader'
});
}
}
const app = new App();
new MyChart(app, 'Job');
app.synth();
