A daemonset that print the most heavy files on each node

daemonset.yaml

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: disk-checker
  labels:
    app: disk-checker
spec:
  selector:
    matchLabels:
      app: disk-checker
  template:
    metadata:
      labels:
        app: disk-checker
    spec:
      hostPID: true
      hostIPC: true
      hostNetwork: true
      containers:
      - resources:
          requests:
            cpu: 0.15
        securityContext:
          privileged: true
        image: busybox
        imagePullPolicy: IfNotPresent
        name: disk-checked
        command: ["/bin/sh"]
        args: ["-c", "du -a /host | sort -n -r | head -n 20"]
        volumeMounts:
        - name: host
          mountPath: "/host"
      volumes:
        - name: host
          hostPath:
            path: "/"

This seems to solve privilages issue when running it on OpenShift cluster:

$ oc create serviceaccount privilegeduser
$ oc adm policy add-scc-to-user privileged -z privilegeduser

# Add ” serviceAccountName: privilegeduser ” into yaml spec, and then apply the file

Happy to hear this was solved!

Just passing by, wanted to thanks for the clever solution.

Thank you :)
