GitHub Actions 提供了一種將 CI/CD 整合到儲(chǔ)存庫中的無縫方式，自動(dòng)執(zhí)行各種任務(wù)，例如執(zhí)行測(cè)試、建置工件和部署專案。

快照的工作流程

此工作流程在非主分支上觸發(fā)或透過工作流程排程事件手動(dòng)觸發(fā)。它包括以下步驟：

• 執(zhí)行測(cè)試：確保您的程式碼通過所有測(cè)試。
• 建立 JAR 檔案：編譯您的 Spring Boot 應(yīng)用程式。
• 建立 Docker 映像並將其推送到 GitHub Docker 註冊(cè)表：從產(chǎn)生的工件建立 Docker 映像並將其推送到 GitHub 容器註冊(cè)表。

發(fā)布的工作流程

此工作流程在將變更推送到主分支時(shí)運(yùn)行，包括以下步驟：

• 建置發(fā)布版本：編譯專案的發(fā)布版本。
• 建立 Docker 映像並將其推送到 GitHub Docker 註冊(cè)表：建立 Docker 映像並將其推送到 GitHub 容器註冊(cè)表。
• 增加 SNAPSHOT 版本：更新 pom.xml 中的版本以用於未來的快照版本。
