Argo CD: Installation and Configuration

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

kubectl create namespace argocd

kubectl apply -n argocd -f \
  https://raw.githubusercontent.com/argoproj/argo-cd/v3.1.9/manifests/install.yaml

To access the Argo CD UI, you need to create a port-forward to the Argo CD server (or expose the service using a LoadBalancer or an Ingress):

kubectl \
  port-forward \
  svc/argocd-server \
  -n argocd \
  8080:443 \
  > /dev/null 2>&1 &

We can now create an SSH tunnel to access the interface:

# On your workspace server
echo $(curl -s ifconfig.me)

# On your local machine
export IP=
ssh -NfL 8080:localhost:8080 root@$IP

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
