Different ways to install ArgoCD

ArgoCD can be installed in multiple ways, depending on your environment and requirements. The main methods include:

1. Using kubectl (Manifest Installation)

• Download the YAML manifests for ArgoCD and apply them directly to your Kubernetes cluster.
• Simple and quick.
• No additional tools required.
• Limited customization during installation.

Example:

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/  install.yaml

2. Using Helm (Recommended for Customization)

• Install ArgoCD using the Helm package manager.
• Highly customizable.
• Integrates well with CI/CD pipelines.
• Requires Helm installed.

Example:

helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
helm install argocd argo/argo-cd -n argocd --create-namespace

3. Using Kustomize

• Clone the ArgoCD repository and customize the installation using kustomize.
• Ideal for advanced users needing a declarative setup.
• Slightly more complex than kubectl.

Example:

git clone https://github.com/argoproj/argo-cd.git
cd argo-cd
kubectl apply -k overlays/stable

4. Terraform

• Use tools like Terraform to provision ArgoCD alongside other Kubernetes resources
• Infrastructure as Code (IaC) for better repeatability.
• Requires Terraform knowledge.

Example:

resource "helm_release" "argocd" {
  name       = "argocd"
  repository = "https://argoproj.github.io/argo-helm"
  chart      = "argo-cd"
}
