이제는 Argo CD를 올려보도록할게요. ArgoCD는 Kubernetes 클러스터에서 애플리케이션을 관리하고 배포하는 데 사용되는 GitOps 기반의 지속적 배포(Continuous Deployment, CD) 도구입니다. 이 도구는 선언적 접근 방식을 채택하여, 애플리케이션과 인프라의 상태를 Git 저장소에 정의된 대로 자동으로 동기화합니다.
머 여러가지 기능이 있지만 실무적이나 학습에서 대부분 차용하고 있는 툴이기도 하고 모든 배포가 Git을 통해 관리되므로 관리/자동화/확장성등이 뛰어납니다.
바로 설치부터 진행할게요. 여러가지 방법이 있지만 저는 Helm으로 설치하겠습니다. Helm이 편하기도하고 관리하기도 좋아서 그렇습니다.
repository부터 추가하도록 할게요
helm repo add argo https://argoproj.github.io/argo-helm
helm repo updatehelm show values argo/argo-cd --version 7.5.2 > values.origin.yaml
cp values.origin.yaml values.yaml여기에서 values.yaml에
global:
domain: argocd.dev.xxxx.com # domain
configs:
params:
server.insecure: true이렇게 수정해줍니다.
사뿐히 설치 명령어 날려줍시다.
helm upgrade --install argocd --namespace argocd --create-namespace -f values.yaml --version 7.5.2 argo/argo-cd
# Release "argocd" does not exist. Installing it now.
# NAME: argocd
# LAST DEPLOYED: Fri Nov 15 13:32:06 2024
# NAMESPACE: argocd
# STATUS: deployed
# REVISION: 1
# TEST SUITE: None
# NOTES:
# In order to access the server UI you have the following options:
# 1. kubectl port-forward service/argocd-server -n argocd 8080:443
# and then open the browser on http://localhost:8080 and accept the certificate
# 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 random password generated during the installation. You can find the password by running:
# kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d마지막 명령어에 살짝만 추가해서 메모장에 기록해두도록합시다. 까먹어두 됩니다.
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d && echo
helm status argocd -n argocd kubectl get all -n argocd
