Installing Argo CD - what do i miss?

[ggruening]

Hello everyone,

maybe it's a beginner's question - but I only relied on the resource in this repo. And it doesn't work straight away with those, so it might be of more interest if we discuss a few tips here and adjust the README at the end if necessary...

I'd like to install Argo CD using Kustomize and a helm chart. I tried the following:

• According to the "Adding Extras" chapter in the README, I created a folder called "extra-manifests/helm-charts/argocd".

• I copied the three files from examples/kustomization_user_deploy/helm-chart into it and only adjusted the domain in helm-chart.yaml.tpl.

• Among the examples in the README there is a note that you should extend the kube.tf for Argo CD. I did that:

  extra_kustomize_deployment_commands = <<-EOT
    kubectl -n argocd wait --for condition=established --timeout=120s crd/appprojects.argoproj.io
    kubectl -n argocd wait --for condition=established --timeout=120s crd/applications.argoproj.io
    kubectl apply -f /var/user_kustomize/argocd-projects.yaml
    kubectl apply -f /var/user_kustomize/argocd-application-argocd.yaml
    ...
  EOT

But running terraform apply leads to:

module.kube-hetzner.null_resource.kustomization_user_deploy[0] (remote-exec): Applying user kustomization...
module.kube-hetzner.null_resource.kustomization_user_deploy[0] (remote-exec): error: unable to find one of 'kustomization.yaml', 'kustomization.yml' or 'Kustomization' in directory '/var/user_kustomize'

What am I missing?

Thanks for a hint,

File names should end with .tpl, such as "argocd-application-argocd.yaml.tpl". Does your file follow this naming convention?

[vaceslav]

I just tested it on my development system: all files should be in the “extra-manifests” directory, not in “helm-chart”.

I use argocd. I set it up directly in a terraform file with helm provider:

`resource "helm_release" "argocd" {
name = "argocd"
repository = "https://argoproj.github.io/argo-helm"
chart = "argo-cd"
version = "5.55.0" # Specify the version you want to install
namespace = "argocd"
create_namespace = true
set {
name = "redis-ha.enabled"
value = "false" # Set the service type to LoadBalancer or NodePort as needed
}

set {
name = "controller.replicas"
value = "1"
}
set {
name = "server.replicas"
value = "1"
}
set {
name = "repoServer.replicas"
value = "2" # Set to "true" to enable Ingress
}
set {
name = "applicationSet.replicas"
value = "2"
}
}`
