ArgoCD CLI 사용하여 App 배포하기

ArgoCD는 CLI를 제공한다. CLI로도 모든 기능을 사용할 수 있다.

---

1. CLI 설치

• Ubuntu 기준으로 아래와 같이 진행하면 된다. 별도 설치과정은 없고 단순히 binary를 받아 옮기는 정도이다.

curl -sSL -o argocd-linux-amd64 https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64
sudo install -m 555 argocd-linux-amd64 /usr/local/bin/argocd
rm argocd-linux-amd64

 

2. CLI로 App 배포

• 예시로 ArgoCD를 통해 Helm을 배포해 보겠다.
• ArgoCD CLI사용을 위해선 UI와 마찬가지로 로그인이 필요하다.

test@DESKTOP-F55SF6V:~ (⎈|test-cluster:default)# argocd login 127.0.0.1:8080
WARNING: server certificate had error: x509: cannot validate certificate for 127.0.0.1 because it doesn't contain any IP SANs. Proceed insecurely (y/n)? y
Username: admin
Password:
'admin:login' logged in successfully
Context '127.0.0.1:8080' updated

• 테스트환경이라 port-forward를 통해 접근했다.

 

• repository 생성 및 확인

test@DESKTOP-F55SF6V:~ (⎈|test-cluster:default)# argocd repo add \
https://charts.bitnami.com/bitnami --type helm --name helm-repo
Repository 'https://charts.bitnami.com/bitnami' added

test@DESKTOP-F55SF6V:~ (⎈|test-cluster:default)# argocd repo list

helm  helm-repo     https://charts.bitnami.com/bitnami            false     false  false  false  Successful

 

• cluster 추가 및 확인

test@DESKTOP-F55SF6V:~ (⎈|test-cluster:default)# argocd cluster add test-cluster
WARNING: This will create a service account `argocd-manager` on the cluster referenced by context `test-cluster` with full cluster level privileges. Do you want to continue [y/N]? y

• in-cluster외에 다른 cluster를 추가할 경우 진행한다.

 

• project 생성 및 확인

argocd proj create helmproj --src https://charts.bitnami.com/bitnami \
--dest https://FE53A82E1A035C54CE7090049E047F46.gr7.ap-northeast-2.eks.amazonaws.com,test

test@DESKTOP-F55SF6V:~ (⎈|test-cluster:default)# argocd proj list

• CLI를 사용해보는 목적이기 때문에 옵션은 최소로 하였으며 옵션설명도 생략하겠다.

 

• Application 생성

test@DESKTOP-F55SF6V:~ (⎈|test-cluster:default)# argocd app create helmtest \
> --repo https://charts.bitnami.com/bitnami \
> --project helmproj \
> --helm-chart nginx --revision 13.2.30 \
> --dest-namespace test --dest-name test-cluster \
> --revision-history-limit 5 \
> --validate=false \
> --sync-policy auto \
> --sync-option Prune=true
application 'helmtest' created

• bitnami chart의 nginx를 배포하였으며 chart version은 13.2.30이다.

• Resource들이 생성된 것을 확인할 수 있다.

• 참고로 동일 application을 yaml형태로 생성도 가능하다.

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: helmtest
  namespace: argocd
spec:
  destination:
    name: test-cluster
    namespace: test

    targetRevision: 13.2.30
  syncPolicy:
    automated: {}
    syncOptions:

반응형

명령어가 깔끔하다는 느낌은 없다. set을 만들어 두고 사용하기엔 괜찮아 보인다.
