Tested that pods work ok:

# daemonset.yaml
apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: test-node-daemonset
  labels:
    app: test-node
spec:
  selector:
    matchLabels:
      app: test-node
  template:
    metadata:
      labels:
        app: test-node
    spec:
      containers:
      - name: busybox
        image: busybox:latest
        command: ["sleep", "3600"]
        resources:
          requests:
            cpu: "100m"
            memory: "64Mi"
          limits:
            cpu: "200m"
            memory: "128Mi"

Then, what didn't work when I tried this before:

kubectl apply -f daemonset.yml
kubectl get pods -o wide
kubectl exec -it $POD_NAME -- sh

However monitoring is failing with:

STDOUT:

Trying manually:

[root@RL9-control ~]# /bin/helm --version=59.1.0 --repo=https://prometheus-community.github.io/helm-charts upgrade -i --reset-values --wait --timeout 5m -f=/tmp/tmp1q6qtlkc.yml kube-prometheus-stack kube-prometheus-stack
Release "kube-prometheus-stack" does not exist. Installing it now.
Error: rendered manifests contain a resource that already exists. Unable to continue with install: ClusterRole "kube-prometheus-stack-grafana-clusterrole" in namespace "" exists and cannot be imported into the current release: invalid ownership metadata; annotation validation error: key "meta.helm.sh/release-namespace" must equal "default": current value is "monitoring-system"

This works, so going thro squid is OK:

[root@RL9-control ~]# curl -L https://prometheus-community.github.io/helm-charts
