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:

# 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
|
||||

||||

```
|
||||
|

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/

Let's create some dummy worklaod that will write something to a PVC
|
||||
|
||||
```yaml
|
||||

|
||||

||||

||||

||||

|
||||

|
||||
volumeMounts:
|
||||
- mountPath: /src
|
||||

|
||||
command:
|
||||

|
||||
args:
|
||||

|
||||
- sleep 1000
|
||||
```
|
||||
|
||||
```shell
|
||||
$ kubectl get pvc
|
||||

||||

|
||||
```
|
||||
|
||||
```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:
|
||||

||||

||||
source:
|
||||

|
||||

|
||||
|
||||
```shell
|
||||
$ kubectl get volumesnapshot

||||
