Introduction

This guide provides step-by-step instructions to deploy ArgoCD on AKS using Terraform, facilitating a GitOps workflow on Azure.

Prerequisites

• Kubectl: Installed. Download here: kubectl for Windows
• Azure CLI: Installed and authenticated with az login.
• AKS Credentials (AKS is up and running): Obtain with az aks get-credentials --resource-group myAksResourceGroup --name myAksCluster.
• Visual Studio Code Base64 Decode and Encode Extension: Installed for handling base64 decodings. Will be used to decode the initial ArgoCD admin password.

Terraform Workflow

# Step 1: Initialize your Terraform workspace
terraform init

# Step 2: Generate and show an execution plan
terraform plan

# Step 3: Apply the changes required to reach the desired state of the configuration
terraform apply

# Step 4: Retrieve the ArgoCD default admin(username) password and decode it using Base64 extension
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}"

# Step 5: Destroy all resources created by the Terraform configuration
terraform destroy
