Installing ArgoCD

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

k get all -n argocd

---

Change the service type of "argocd-server" from "ClusterIP" to LoadBalancer

For the argocd to utilize Metallb, we have to change the service type of "argocd-server" service from "ClusterIP" to "LoadBalancer"

k edit service argocd-server -n argocd

k get all -n argocd

Now we see that the service type of "argocd-server" service has been changed from "ClusterIP" to "LoadBalancer".
