Deploy victoria-metrics-k8s-stack using different storageClass than default about helm-charts

[Angel0r]

I managed to solve the problem by setting the created storageClass as default:

annotations: 
  storageclass.kubernetes.io/is-default-class: "true"

Hello @Angel0r ,
Have you tried specified the storageClassName under their StorageSpec, like for vmstorage

kind: VMCluster
metadata:
  name: example-vmcluster
spec:
  vmstorage:
    replicaCount: 2
    storage:
      volumeClaimTemplate:
        spec:
          storageClassName: prod-sc

@Angel0r, It's possible to set the storageClassName via the helm values. Just make sure you follow the resource spec.

Here's a snippet where I've specified storageClassName in my helm values for VMSingle:

{
...
"vmsingle": {
    "annotations": {},
    "enabled": true,
    "spec": {
        "image": {
            "tag": "v1.101.0"
        },
        "retentionPeriod": "30",
        "replicaCount": 1,
        "extraArgs": {},
        "storage": {
            "storageClassName": "efs-sc",
            "accessModes": [
                "ReadWriteOnce"
            ],
            "resources": {
                "requests": {
                    "storage": "20Gi"
                }
            }
        }
    },
...
}

helm successfully templates the storageClassName into the VMSingle spec:

apiVersion: operator.victoriametrics.com/v1beta1
kind: VMSingle
metadata:
  labels:
    app.kubernetes.io/instance: vmo-helm-c8ce5482

  extraArgs:
    vmalert.proxyURL: http://vmalert-vmo.vm.svc:8080

  retentionPeriod: "30"
  storage:
    accessModes:
      - ReadWriteOnce

      requests:
        storage: 20Gi
    storageClassName: "efs-sc"
