ArgoCD on EKS

1. Install Argo CD

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

kubectl create namespace argocd
kubectl apply -n argocd --server-side --force-conflicts \
  -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

2. Expose with a LoadBalancer

kubectl patch svc argocd-server -n argocd \
  -p '{"spec": {"type": "LoadBalancer"}}'

Get the URL:

export ARGOCD_SERVER=$(kubectl get svc argocd-server -n argocd \
  -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
echo "Argo CD URL: https://$ARGOCD_SERVER"

3. Get the admin password

The default username is admin. The password is stored in a Kubernetes secret:

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

Or save it to a variable:

export ARGOCD_PWD=$(kubectl -n argocd get secret argocd-initial-admin-secret \
  -o jsonpath="{.data.password}" | base64 -d)
echo "Argo CD admin password: $ARGOCD_PWD"

Log in:

argocd login "$ARGOCD_SERVER" --username admin --password "$ARGOCD_PWD" --insecure
