Argo CD: Installation and Configuration

Argo CD can be installed on a Kubernetes cluster using the following command:

# First create the argocd namespace
kubectl create namespace argocd

# Then install Argo CD using the official manifest
kubectl apply -n argocd -f \
  https://raw.githubusercontent.com/argoproj/argo-cd/v3.2.1/manifests/install.yaml

To access the Argo CD UI, you need to create a port-forward to the Argo CD server, expose the service using a LoadBalancer, a NodePort, or use an Ingress controller. For simplicity, we will use a NodePort service.

kubectl patch svc argocd-server \
  -n argocd \
  -p '{"spec": {"type": "NodePort", "ports": [{"port": 443, "targetPort": 8080, "nodePort": 30007}]}}'

We can now access the Argo CD UI using the following URL:

echo "https://$MASTER_PUBLIC_IP:30007"

The default username is admin, and the password can be retrieved using the following command:

kubectl \
  -n argocd \
  get secret \
  argocd-initial-admin-secret \
  -o jsonpath="{.data.password}" | \
  base64 -d; echo

To install the Argo CD CLI, use the following commands:

# Download the binary
curl -sSL -o argocd-linux-amd64 \
  https://github.com/argoproj/argo-cd/releases/download/v3.2.1/argocd-linux-amd64

# Install the binary
install -m 555
