对 maven 但非 Java 应用程序使用 jib

Using a jib for maven but non-Java application

我正在创建项目并使用 Jib 创建容器并将它们推送到 ECR。这是一个多模块 Maven 项目,有 3 个子模块,其中 2 个是标准的 java spring-boot 项目,可以与 Jib 一起正常工作,另一个是 npm 项目,使用MVN。这是它的 pom。

Spotify one 是我们以前做的方式,现在我们转向 Jib。但是我遇到了这个应用程序构建的问题,

    [ERROR] Failed to execute goal com.google.cloud.tools:jib-maven-plugin:2.7.1:build (default-cli) on project my-search-frontend: Obtaining project build output files failed; make sure you have compiled your project before trying to build the image.

应用的项目结构

非常感谢对此的帮助。

JIB 仅适用于 java 个项目。它处理在优化层中安装 Java 运行时和依赖项。但它无法创建 NPM docker 个图像。

所以你只能为java个模块启用jib-maven-plugin maven插件。

对于 NPM,您应该坚持使用 spotify docker-maven-plugin 或类似的东西。 或者 fabric8 试试看。

Jib Maven 和 Gradle 插件适用于 Java 应用程序,错误消息抱怨 NPM 模块中没有已编译的 .class 文件。但是,从技术上讲,您可以使用一些技巧让 Jib 构建 NPM 映像(例如,在 src/main/java 下放置一个虚拟 DummyClass.java 以绕过错误,覆盖 <container><entrypoint> 以不执行java,使用<extraDirectories> to put arbitrary files, set <from><image> to use a non-JRE base image, etc.). You may also need to remove files using the Jib Layer-Filter extension。但是,由于 Jib 确实是为 Java 个应用量身定制的,所以我不能真正推荐它。

仅供参考,Jib 可以通过 Jib Extension Framework 进行高度自定义和扩展,因此理论上您可以编写一个 NPM Jib 扩展来涵盖这个高度专业化的工作流程(并与 Jib 社区共享)。

对于非 Java 应用程序和非 Maven 工作流,我们还有其他 Jib 解决方案:Jib Core (the Java library) and Jib CLI. Jib CLI may work in this case, although it's a not a Maven plugin. (I don't know if it's a good idea, but FYI, there seems a few ways to run an arbitrary command in Maven。)


相关,此 article 显示了一个示例,该示例使用 Jib Layer-Filter 扩展来启用 Jib 不支持的用例。

如果有人仍在期待,请提供替代方案(这是我的 google 搜索的第一个命中):

您可以将 jib 插件设置为使用打包的 .jar 文件,如果您使用 mvn package,它会自动生成,如果不存在代码,它会非常小 (~2kb)

还要确保您的项目没有父项或依赖项,否则 jib 会将库复制到图像中。

创建它:mvn clean package jib:dockerBuild

使用dive检查是否添加了不必要的文件
