1. Argo CD 설치하기
namespace 생성하기
kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml2. Argo CD CLI 설치
Argo CD CLI 참고 사이트 : https://argo-cd.readthedocs.io/en/stable/cli_installation/
Installation - Argo CD - Declarative GitOps CD for Kubernetes
Installation You can download the latest Argo CD version from the latest release page of this repository, which will include the argocd CLI. Linux and WSL ArchLinux Homebrew Download With Curl Download latest version curl -sSL -o argocd-linux-amd64 https:/
argo-cd.readthedocs.io
Argo CD의 version 확인
VERSION=$(curl --silent "https://api.github.com/repos/argoproj/argo-cd/releases/latest" | grep '"tag_name"' | sed -E 's/.*"([^"]+)".*/\1/')
/* 확인한 버전으로 다운 받기 */
curl -sSL -o /usr/local/bin/argocd https://github.com/argoproj/argo-cd/releases/download/$VERSION/argocd-linux-amd64
/* 실행권한 부여 */
chmod +x /usr/local/bin/argocd
3. Argo CD API Server 외부 접속 허용
/* NodePort로 셋팅 */
kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "NodePort"}}'
/* LoadBalancer 는 클라우드 업체만 사용가능 */
kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'
4. port forwarding은 service 노출없이 API Server에 연결가능
kubectl port-forward svc/argocd-server -n argocd 8080:443
5. CLI를 사용하여 로그인
- 계정(admin) 의 초기 비밀번호는 Argo CD 설치 네임스페이스에 password이름이 지정된 비밀 필드에 텍스트로 저장됩니다.
아래 CLI 를 사용하여 비빌번호 검색
argocd admin initial-password -n argocdroot@master:~# argocd admin initial-password -n argocd
