Managing Kubernetes Jobs

You can use Shipa to manage Jobs using a simple definition file.

Shipa automatically creates job-related objects required by Kubernetes to run your jobs.

Shipa 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 Shipa.

Run Jobs

Job can be deployed in the context of a framework. See Framework Management for details about managing Framework.

# Create a team dev
shipa team create dev
# Create framework 
shipa framework add framework1 --team dev

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

name: pi-job 
type: Job 
Description: “This is Pi Job”
framework: framework1
team: dev
image: perl 
parallelism: 1

backOffLimit: 2  # Optional, default 6
command: ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"] # Required
policy: # Optional
    restartPolicy: Never
containers:
    - name: pi
      image: perl
      command: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
    - name: rootdir
      image: ubuntu
      command: ["ls", "/"]
shipa job run pijob.yaml
