+# Pipeline Script Description
+
+
+## Source Code Deploy 시 세 가지 Stage로 진행된다.
+
+  - **Docker Build**
+    - Storage(TB2-DOCKER) 시스템에서 최신(**.gitlab-ci.yaml** 먼저 수행)의 /GIT/docker_hongsnet 경로에서 Container Image를 Build한다.
+  - **Harbor Repository Image Push**
+    - Storage 시스템에서 harbor.hongsnet.net, Private Registry에 로그인을 수행
+    - Build 된 Container Image를 **Tagging** 한다.
+    - Tagging된 Container Image를 저장소에 **Push** 한다.
+  - **K8s Image Rolling Update**
+    - Storage 시스템(**K8s의 Master이기도 함**)에서 업데이트 이미지에 대해 `Rolling Update`를 수행한다.
