Create argocd namespace

A Kubernetes namespace is a mechanism for isolating groups of resources within a single cluster, providing a scope for names and enabling logical organization for multiple users, teams, or projects.

kubectl create namespace argocd

> kubectl get namespaces
NAME              STATUS   AGE
argocd            Active   80s

Apply the official installation manifest

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

Wait for all pods to be in the Running state

kubectl get pods -n argocd --watch
