Ephemeral storage

[Edarjak]

Hi community,

I have a K3S cluster with ARC controller running. Here is my RunnerDeployment:

apiVersion: actions.summerwind.dev/v1alpha1
kind: RunnerDeployment
metadata:
  name: github-actions-runners-micro
  namespace: github-actions-runners-micro
spec:
  replicas: 6
  template:
    spec:
      organization: myorg
      labels:
        - x-micro
        - micro
      group: Default
      resources:
        limits:
          cpu: "0.25"
          memory: "0.5Gi"
          ephemeral-storage: "20Gi"
        requests:
          cpu: "0.125"
          memory: "0.5Gi"
          ephemeral-storage: "20Gi"
      containers:
        - name: docker
          image: my-docker-images.artifactory.myhost.com/repo/docker:dind
        - name: runner
          image: my-docker-images.artifactory.myhost.com/repo/runners:runner

By default, for the ephemeral storage it uses hosts /var and /tmp or /var/tmp dirs (sda). The problem is that there are not enough space on the sda drive, so I have added another disk (sdb) and wondering is it possible to instead of early mentioned dirs make it to use /data on the sdb?

Thanks in advance,
