title: "Argocd vs Helmfile: Helmfile"

In two previous posts I've described how it's possible to install a couple of applications with [`Applications`]({{< ref "argocd-vs-helmfile-application" >}}) and [`ApplicationSets`]({{< ref "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:
The main file is `/helmfile.yaml`
```YAML
---
{{ readFile "releases.yaml" }}
bases:
- environments.yaml
- repositories.yaml
releases:
helmfiles:
- path: {{.Environment.Name }}/helmfile.yaml
```
You can see several imports here, let's check them one by one:
```YAML
# releases.yaml <- here we will define all the charts that are going to be used by helmfile. It's a templating layer, so we don't have to copy-paste a lot of yaml stuff
---
templates:
# It's supposed to be empty when nothing is installed, but I've decided to show that helmfile also can be used to manage CRDs. With this hooks, you'll be able to install CRDs with helmfile, see diffs when updating and update them while updating releases. But I need to say that I haven't checked how it's wotking on big systems, so consider this thing experimental
crd-management-hook: &crd-management-hook
hooks:
- events: ["preapply"]
showlogs: true
command: "sh"
args:
- -c
- "helm show crds {{ .Release.Chart }} --version {{ .Release.Version }}| kubectl apply -f -"
- events: ["prepare"]
showlogs: true
command: "sh"
args:
- -c
- "helm show crds {{ .Release.Chart }} --version {{ .Release.Version }} | kubectl diff -f - || true"
- events: ["postuninstall"]
showlogs: true
command: "sh"
args:
- -c
- "helm show crds {{ .Release.Chart }} --version {{ .Release.Version }} | kubectl delete -f -"
# environments.yaml
---
# Here you can define all you clusters so you can sync helmfiles using the `-e` flag
# helmfile -e cluster_test sync
environments:
cluster_test:
kubeContext: kind-kind
cluster1:
kubeContext: kind-kind
cluster2:
kubeContext: kind-kind
# repositories.yaml
---
# it's empty now, because we have nothing installed yet. But here we will add all the helm repos to avoid copy-paste again.
repositories:
```
Also there is a more complicated and less obvious import:
```YAML
helmfiles:
- path: {{.Environment.Name }}/helmfile.yaml
```
It's going to import helmfiles that are not used across all clusters. So if you want to install something to `cluster-2` across, you will add it to the `/cluster2/helmfile.yaml` and sync the main helmfile. I will show an example later.
So we're all set and ready to begin installing new stuff.
- Add a new repo to `repositories.yaml`
```YAML
repositories:
- name: fairwinds-stable
url: https://charts.fairwinds.com/stable
```
- Add new charts to `releases.yaml`
```YAML
releases:
vpa: &vpa
name: vpa
chart: fairwinds-stable/vpa
version: 1.6.0
values:
- common/{{ .Release.Name }}/values.yaml
inherit:
template: crd-management-hook # <- Here we are using the crd-management-hook, so VPA CRDs are managed outside of helm itself
goldilocks: &goldilocks
name: goldilocks
chart: fairwinds-stable/goldilocks
version: 6.5.0
```
And now we only need to say to which clusters we want to install those releases. So to the main `helmfile.yaml` I'm adding this:
```YAML
releases:
- <<: *vpa
installed: true
namespace: vpa-system
createNamespace: true
```
And to `cluster2/helmfile.yaml` and `cluster_test/helmfile.yaml` I'm adding:
```YAML
releases:
- <<: *goldilocks
installed: true
namespace: vpa-system
```
Let's see how the CI could be implemented with this setup.
- If branch is not `main`
- `helmfile -e cluster_test apply`
- `helmfile -e cluster1 diff`
- `helmfile -e cluster2 diff`
- If branch is `main`
- `helmfile -e cluster_test apply`
- `helmfile -e cluster1 apply`
- `helmfile -e cluster2 apply`
{{< details "Diffs will look like that:" >}}
```YAML
Comparing release=goldilocks, chart=fairwinds-stable/goldilocks

Yeah, it's huge, but you can see everything that's going to happen. So I'd say it's good.
## Conclusion
It's a short article, because I think the whole setup is super easy, CI is easy too. You still have a full `GitOps` (or almost full) but you also have control. I love this setup and would like to use it for my infrastructure.
Why do I think it's better that `ArgoCD`?
With `ArgoCD` I either have a lot of `yaml` to install things, or I have complicated setups with `ApplicationSets` that are most probably very special and won't be reused in other companies. I need to care about how `ArgoCD` will handle a lot of applications that are added there only for diffing. I need additional applications installed in my clusters not only as a part of infrastructure itself, but also as a service that I'm providing other teams with. Because I want to manage applications that are being developed by other teams with `Argo`, so I'm mixing a lot of different kinds of applications here.
Helmfile lets me separate infra from applications. `ArgoCD` can be only provided as a service, and other teams can use, because it's making k8s easier for those who don't need to understand it so deeply. Also, helmfile lets me use helm-secrets to encrypt values. I can do it with Argo too, but then I need to either have a custom `ArgoCD` image, or support a CMP plugin, that will handle SOPS.
You can find an example of PR here: <https://git.badhouseplants.net/allanger/helmfile-vs-argo/pulls/1/files>
> When helmfile is not GitOps?
> To uninstall a helm release, you need to add `isntalled: false` to it. If you just remove a release from helmfile.yaml, it isn't going to be removed. So in such cases it's not GitOps. You can write a hook, that is comparing a previous state of your helmfile to the current one and doing a cleanup, then it's again fully GitOps. But I prefer removing things manually, so to me, it's not a problem. Removing stuff is something that I think should be mostly done by a human being, if it's not a part of your daily work.
Thanks,
Oi!
