Job Management
You can use Ketch to manage Jobs using a simple definition file.
Ketch automatically creates all job-related objects required by Kubernetes to run your jobs.
Ketch reduces the learning curve associated with Kubernetes adoption, simplifies the deployment process, and gives you a job context view post-deployment.
The sections below describe how you can manage your job's lifecycle on Kubernetes using Ketch.
Deploying Jobs
You first need to create a framework:
ketch framework add myframework --ingress-service-endpoint INGRESS_IP_ADDRESS --cluster-issuer let --ingress-type traefik
Deploy a job using a definition file.
Below is a sample job YAML file for job pi-job
that executes a pi function in a container in framework myframework
:
name: pi-job
type: Job
framework: myframework
description: "Pi job"
containers:
- name: pi
image: perl
command:
- "perl"
- "-Mbignum=bpi"
- "-wle"
- "print bpi(2000)"
ketch job deploy pijob.yaml
List Job
ketch job list
NAME VERSION FRAMEWORK DESCRIPTION
pi-job v1 myframework Pi job
Remove Job
ketch job remove JOB_NAME
Export Job
You can export a Ketch deployed job to a YAML file.
ketch job export JOB_NAME
Running ketch job export pi-job
should print:
backoffLimit: 6
completions: 1
containers:
- command:
- perl
- -Mbignum=bpi
- -wle
- print bpi(2000)
image: perl
name: pi
description: Pi job
framework: myframework
name: pi-job
parallelism: 1
