 [Do you remember?]({{< ref "dont-use-argocd-for-infrastructure" >}})
 > And using `helmfile`, I will install `ArgoCD` to my clusters, of course, because it's an awesome tool, without any doubts. But don't manage your infrastructure with it, because it's a part of your infrastructure, and it's a service that you provide to other teams. And I'll talk about in one of the next posts.

 In two previous posts I've described how it's possible to install a couple of applications with [`Applications`]({{< relref "/post/allanger/argocd-vs-helmfile-application" >}}) and [`ApplicationSets`]({{< relref "/post/allanger/argocd-vs-helmfile-applicationset" >}}), and this one is the last in a row. And here I'm going to install the same applications (`VPA` and `Goldilocks`) with helmfile, and I will tell why I think that it's better than `ArgoCD`

 So let's start. Here you can find the [initial config](https://git.badhouseplants.net/allanger/helmfile-vs-argo/src/branch/helmfile-main). Let's see what we got here:

+# Intro
+
+# Installing
+
+I've created a new empty k3s cluster, into which I've installed `coreDNS`,  `cilium`, and `local-path-provisioner` by Rancher.
+
+```shell
+$ kubectl get pods -A
+NAMESPACE     NAME                                     READY   STATUS    RESTARTS   AGE
+kube-system   cilium-operator-9c465d6d8-jlbc9          1/1     Running   0          72s
+kube-system   cilium-gzwlp                             1/1     Running   0          72s
+kube-system   local-path-provisioner-6896b5f8c-7mpfl   1/1     Running   0          50s
+kube-system   coredns-7db6d4f6d7-vqhpc                 1/1     Running   0          61s
+```
+
+Now let's install the external-snapshooter, the project source code can be found here: <https://github.com/kubernetes-csi/external-snapshotter>, but they don't provide us with a helm chart, so I'll install it using that one <https://github.com/piraeusdatastore/helm-charts/tree/main/charts/snapshot-controller>
+
+```shell
+$ helm repo add piraeus-charts https://piraeus.io/helm-charts/
+
+$ helm install snapshot-controller piraeus-charts/snapshot-controller -n kube-system
+
+$ kubectl get pods -A
+NAMESPACE     NAME                                           READY   STATUS    RESTARTS   AGE

+kube-system   snapshot-validation-webhook-79f9c6bb5f-p6hqx   1/1     Running   0          16s
+
+$ kubectl get crd

+```
+
+Let's create some dummy worklaod that will write something to a PVC
+
+```yaml
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: test
+spec:
+  storageClassName: local-path
+  accessModes:
+    - ReadWriteOnce
+  resources:
+    requests:
+      storage: 1Gi
+---
+apiVersion: v1
+kind: Pod
+metadata:
+  name: test
+spec:
+  volumes:
+    - name: test
+      persistentVolumeClaim:
+        claimName: test
+  containers:
+    - name: test
+      image: alpine
+      volumeMounts:
+        - mountPath: /src
+          name: test
+      command:
+        - sh
+      args: 
+        - -c 
+        - sleep 1000
+```
+
+```shell
+$ kubectl get pvc
+NAME   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
+test   Bound    pvc-4924e25f-84ae-4640-8199-0156659cb167   1Gi        RWO            local-path     2m7s
+```
+
+```shell
+$ kubectl exec -it test -- sh
+# -- Inside the container
+$ echo 1 > /src/test
+$ cat /src/test
+1
+```
+
+So now let's try creating a snapshot
+```yaml
+apiVersion: snapshot.storage.k8s.io/v1
+kind: VolumeSnapshot
+metadata:
+  name: test-snapshot
+spec:
+  source:
+    volumeSnapshotContentName: test
+```
+
+```shell
+$ kubectl get volumesnapshot
+```
