一般來說在軟體交付的過程中,開發的環境可能會有
1.開發環境( DEV )
2.測試環境 ( QAT )
3.使用者測試環境( UAT )
4.生產環境 ( PROD )   
當專案越來越多時,多個環境,越複雜時,過去的手工佈署應用程式,就可能是件麻煩事,且人工佈署很有可能因不小心,造成環境部署錯誤的問題,那麼為了解決這個問題及節省時間,而需要導入 CICD 工具,達到自動建置及自動佈署
在軟體工程中,CI/CD或CICD通常指的是持續集成和持續交付或持續部署的組合實踐。CI/CD通過在應用程式的構建、測試和部署中實施自動化,在開發和運營團隊之間架起了橋樑。 現代DevOps實踐涉及軟體應用程式在整個開發生命周期內的持續開發、持續測試、持續集成、持續部署和持續監控。 (維基百科)

Gitlab Pipelines 真是個好東西,且完全免費,我一台伺服器都沒架,雲端Gitlab,搭配地端的 Runner ,就讓我輕易的做到 CICD ,並讓 Line Bot 通知相關人員,應用程式正在部署程式。
