### EKS blueprint:
https://catalog.us-east-1.prod.workshops.aws/workshops/67bc4d75-6f22-4480-9fb1-30161069e6ff/ko-KR/eks/argocd

git : https://github.com/sykang808/my-eks-blueprints.git

cd ~/environment
git clone https://github.com/sykang808/my-eks-blueprints.git
cd my-eks-blueprints

npm i
cdk deploy cluster-stack

### 필요한 툴 설치

wget https://gist.githubusercontent.com/didhd/66ddcc71610f98a2b159b5afab650e88/raw/4d7bbb1cc0c5c13f961afe087d1f5ab6ee04e4fa/cloud9-prereq.sh
sh cloud9-prereq.sh

### ArgoCD CLI 설치

sudo curl -sSL -o /usr/local/bin/argocd https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64
sudo chmod +x /usr/local/bin/argocd

### ArgoCD 로그인 및 클러스터 등록

ArgoCD 서버를 Load Balancer를 이용하여 외부에 노출합니다.

## argoCD expose
kubectl patch svc blueprints-addon-argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'

아래 입력을 통해 argocli로 ArgoCD 서버에 로그인합니다.

## server env
export ARGOCD_SERVER=`kubectl get svc blueprints-addon-argocd-server -n argocd -o json | jq --raw-output '.status.loadBalancer.ingress[0].hostname'`

## password env
export ARGO_PWD=`kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d`

## argocd cli login
argocd login $ARGOCD_SERVER --username admin --password $ARGO_PWD --insecure

생성한 클러스터를 argocd에 등록합니다.

## argocd cluster add
CONTEXT_NAME=`kubectl config view -o jsonpath='{.current-context}'`
argocd cluster add $CONTEXT_NAME
