3. ArgoCd가 제공하는 템플릿 소스 Install

4. argo-cd-3.29.4.tgz 파일 압축 해제

$ tar -xvzf argo-cd-3.29.4.tgz

 

5. 압축 해제 후 argo-cd 폴더 내부 values.yaml 편집

  ## Server service configuration
  service:
    # -- Server service annotations
    annotations:
      service.beta.kubernetes.io/aws-load-balancer-type: "nlb"
      service.beta.kubernetes.io/aws-load-balancer-subnets: subnet-0b0b22ec4efdxxxx, subnet-025c8eb524217xxxx, subnet-019014e891baexxxx
    # -- Server service labels
    labels: {}
    # -- Server service type
    type: LoadBalancer

- annotation:

  service.beta.kubernetes.io/aws-load-balancer-type: "nlb"
  service.beta.kubernetes.io/aws-load-balancer-subnets: [eks-cluster-public-subnet]

6. 수정한 values.yaml 파일을 helm을 이용하여 ArgoCD Install

$ helm install argo -n argo argo/argo-cd -f values.yaml

$ helm list -n argo
