  1. Jib 打包 Java 應 用 的那些事 心 得分享與擴充攻略 Matt Ho

  2. Hi, I'm Matt 👋 - 松凌科技 Architect / R&D -

    JCConf Speaker - in/methodho - github.com/shihyuho

  3. Lab github.com/shihyuho/jcconf2024-jib

  4. 今天講什麼?

  5. Image 裡有什麼

  6. Fat Jar

  7. Fat Jar - Dockerfile

  8. Fat Jar - Layers

  9. Jib

  10. Jib - Layers

  11. 喜歡 Jib 的原因 1. Daemonless 2. No more Dockerfiles 3.

    Well integrated with build tools (Maven/Gradle) 4. Optimized for improved layer caching 5. Extensible (等等~ 這啥?)

  12. 有時候我們會需要 自 定義 entrypoint

  13. 原來是 Jib 忽略了 <jvmFlags>

  14. Jib 的擴充 softleader/jib-jvm-flags-extension-maven A Jib maven extension outputs the configured

    <jvmFlags> into the /app/jib-jvm-flags-file file, allowing a custom entrypoint to access these flags.

  15. Jib 怎麼擴充

  16. 多了 一 個 Layer

  17. 現在的 entrypoint 長這樣

  18. 更多的應 用 softleader/memory-calculator 基於 paketo-buildpacks/libjvm 的 JVM 記憶體計算 工 具

  19. Recap - Image 的組成 - 打包成 Image 的幾種 方 式

    - 喜歡 Jib 的原因 - Jib 的擴充及延伸應 用

  20. Thank you 🙌
