Deploying Argo CD in Kubernetes with Helm Chart

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It ensures that your Kubernetes applications are always in sync with the desired state defined in your Git repository. This enables a more secure, reliable, and automated deployment process.

Prerequisites

• A running Kubernetes cluster (you can use Minikube for local development)
• kubectl installed and configured to interact with your cluster
• Helm installed

Step-by-Step Guide

1. Add the Argo CD Helm Repository

Add the official Argo CD Helm repository to Helm:

helm repo add argo https://argoproj.github.io/argo-helm
helm repo update

2. Create a Namespace for Argo CD

Create a dedicated namespace for Argo CD:

kubectl create namespace argocd

3. Install Argo CD using Helm

Install Argo CD into the argocd namespace:

helm install argocd argo/argo-cd --namespace argocd

4. Verify Installation

Check the status of Argo CD pods to ensure they are running:

kubectl get pods -n argocd

5. Access the Argo CD UI

Forward the Argo CD server port to access the UI:

kubectl port-forward svc/argocd-server -n argocd 8080:443

Access the Argo CD UI at https://localhost:8080 in your browser.

6. Log In to Argo CD

Retrieve the initial password for the admin user:

kubectl get pods -n argocd -l app.kubernetes.io/name=argocd-server -o jsonpath='{.items[*].metadata.name}'

Log in using the following credentials:

• Username: admin
• Password: Use the pod name retrieved above.

Conclusion

Deploying Argo CD with Helm in Kubernetes provides a robust solution for managing Kubernetes applications with GitOps practices. By following these steps, you can efficiently set up Argo CD and streamline your application deployments.
