Gitops 4대원칙
- Declarative (선언적 구성)
- “무엇을 원하는지”만 정의, 실행 방법은 명시하지 않음.
- 예: “컨테이너 3개 사용”을 선언하면, 시스템이 자동으로 상태를 맞춤.
- Versioned & Immutable (버전 관리 및 불변성)
- Git과 같은 버전 제어 시스템을 단일 진실 원천(single source of truth)으로 사용.
- 모든 변경 이력은 추적 가능하고 불변함.
- Pulled Automatically (자동화된 반영)
- Git 저장소의 변경 사항이 자동으로 시스템에 반영되어야 함.
- 수동 배포 작업이 없어야 함.
- Continuously Reconciled (지속적인 일치 및 조정)
- 현재 상태와 선언된 상태를 지속적으로 비교하여 자동으로 일치시킴.
- 이를 폐쇄 루프(closed loop) 제어라 함.

2장. ArgoCD 시작하기
ArgoCD란?
Argo CD는 선언적인 쿠버네티스의 깃옵스 CD Continuous Delivery 도구다
핵심 개념 및 용어 정리
- Argo CD는 깃 리포지터리에 선언된 의도한 상태(Helm 차트 등) 를 쿠버네티스 클러스터의
- 현재 상태와 비교·동기화하는 조정(Reconciling) 루프를 수행한다.이 과정에서 helm install 대신 kubectl apply 를 사용해, 깃옵스의 선언적 배포 원칙을 유지한다.
용어정리.
- 애플리케이션 application
- 쿠버네티스 리소스 그룹은 매니페스트에 의해 규정된다. Argo CD에서는 CRD 에서 규정한다.
- 애플리케이션 소스 타입 application source type
- 헬름, Kustomize, jsonnet 과 같이 애플리케이션을 구축하는 데 사용하는 도구다.
- 타깃 상태 target state
- 애플리케이션의 의도한 상태를 이야기하며 원천 소스인 깃 리포지터리를 의미한다.
- 현재 상태 live state
- 애플리케이션의 현재 상태로 쿠버네티스 클러스터에 배포된 상태를 의미한다.
- 동기화 상태
- 현재 상태와 타킷 상태가 일치하는지 확인한다.
- 즉, 쿠버네티스에 배포된 애플리케이션이 깃 리포지터리에서 설명된 의도한 상태와 일치하는지 여부를 확인한다.
- 동기화 sync
- 쿠버네티스 클러스터에 변화를 적용해 애플리케이션을 타깃 상태로 변경한다.
- 동기화 동작 상태 sync operation status
- 동기화 단계에서 작업이 실패인지 성공인지 여부를 보여준다.
- 새로고침 refresh
- 깃 리포지터리의 최신 코드와 현재 상태의 차이점을 비교한다.
- 서비스 상태 health status
- 애플리케이션이 요청을 받을 수 있고 운영 중인 상태인지를 말해준다.

ArgoCD 동기화
- 동기화(Sync) 는 Kubernetes 클러스터에 변경사항을 적용해 애플리케이션을 원하는 상태(Target State) 로 만드는 과정이다.
- 이 과정은 여러 단계별 Hook(리소스 훅) 으로 나뉘며, 특정 시점에 원하는 작업을 실행할 수 있다.
동기화 윈도우 확인
(⎈|kind-myk8s:N/A) zosys@4:~/ArgoCD$ kubectl apply -f app-project.yaml -n argocd
Warning: resource appprojects/default is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.
