Problem

You want to use Google’s Autopilot for your gitlab runners, but your job/builds fail because of low resources (ie ephemeral storage).

Solution

You can use a limit range to increase the limits for ephemeral storage or/and memory that will make Google’s autopilot to use them and scale them appropriately.

Create a limit range file like:

apiVersion: v1
kind: LimitRange
metadata:
  name: limit-ephemeral-storage
spec:
  limits:
  - default:
      ephemeral-storage: "10Gi"
      memory: "16Gi"
    defaultRequest:
      ephemeral-storage: "10Gi"
      memory: "16Gi"
    type: Container

And then apply it to your cluster

kubectl -n namespace apply -f limit_range.yaml
