ArgoCD

ArgoCD setting

argocd는 보통 helm 으로 많이 설치를 진행 한다. 본 가이드에서도 역시 helm 을 이용 할 예정이다. 그리고 초기 설치 시 쿠버 내부에만 설치가 되기 때문에 외부에서 접속 할 수 있는 방법은 제한적이다. 그렇기에 셋팅시 ALB도 같이 셋팅 되도록 진행 되어야 한다. ingress-controller는 사전에 설치가 되어 있어야 한다. (EKS->3.Addon->ingress.md 참조)

argocd admin password 생성(선택)

패스워드를 생성한 뒤 이 값을 초기 yaml에 넣으면 초기부터 패스워드 셋팅을 할 수 있다.

argocd account bcrypt --password admin

NOTES:
In order to access the server UI you have the following options:

1. kubectl port-forward service/argocd-server -n default 8080:443

    and then open the browser on http://localhost:8080 and accept the certificat e

2. enable ingress in the values file `server.ingress.enabled` and either
      - Add the annotation for ssl passthrough: https://argo-cd.readthedocs.io/en/stable/operator-manual/ingress/#option-1-ssl-passthrough
      - Set the `configs.params."server.insecure"` in the values file and terminate SSL at your ingress: https://argo-cd.readthedocs.io/en/stable/operator-manual/ingress/#option-2-multiple-ingress-objects-and-hosts


After reaching the UI the first time you can login with username: admin and the andom password generated during the installation. You can find the password by 
running:

kubectl -n default get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

(You should delete the initial secret afterwards as suggested by the Getting Started Guide: https://argo-cd.readthedocs.io/en/stable/getting_started/#4-login-using-the-cli)
