Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes applications. This is a post to show how to enable Argo CD on local k8s and AWS EKS, deploy applications and sync with GitHub manifests.

• Argo CD install ingress controller ingress-nginx

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

• Download and install Argo CD CLI

curl -sSL -o argocd-linux-amd64 https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64
sudo install -m 555 argocd-linux-amd64 /usr/local/bin/argocd
rm argocd-linux-amd64

• Configure Argo CD API Server and deploy zackweb

Change the argocd-server service type to NodePort, initialize admin password, and deploy "zackweb" via Argo CD application manifests (argo-zackweb-application.yaml).

kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "NodePort"}}'
argocd admin initial-password -n argocd
kubectl create -f argo-zackweb-application.yaml

argo-zackweb-application.yaml
