Batch Job Examples

Min Member Override

By default, batch jobs have a minMember of 1, meaning pods are scheduled independently. Use the kai.scheduler/min-member annotation to require a minimum number of pods to be scheduled together (gang scheduling).

kubectl apply -f batch-job-min-member.yaml

This creates a job with parallelism: 6 but requires at least 2 pods to be schedulable before any pod starts running. The annotation value must be a positive integer.

External PodGroup

Use external-podgroup-job.yaml when the PodGroup is created manually or by another controller and the Job should join it without podgrouper interference.

kubectl apply -f external-podgroup-job.yaml

This example shows:

  • An explicit PodGroup resource with queue and subgroup definitions.
  • kai.scheduler/skip-podgrouper: "true" on the Job.
  • pod-group-name on the pod template annotations.
  • kai.scheduler/subgroup-name on the pod template labels.
