因为我的操作系统是macOS，所以下面的步骤在mac上安装

安装GraalVM

  1. 下载macOS上的GraalVM安装包
    https://github.com/graalvm/graalvm-ce-builds/releases/tag/vm-21.1.0
    选择mac版本，我选择的是jdk11的的版本
    下载完成后 本地会有
    graalvm-ce-java11-darwin-amd64-21.1.0.tar.gz
  2. 安装
    参考 https://www.graalvm.org/docs/getting-started/macos/
  3. 安装 native-imag
    在GraalVM虚拟机目录/bin目录下，
    /gu install native-image
    注意，可能需要fq
  4. 使用https://start.springboot.io/ 生成spring-native源代码
  5. mvn -Pnative -DskipTests packag
  1. 启动target目前下的native文件

使用Spring Boot Buildpacks support产生docker镜像

  1. 本机安装docker环境
  2. 使用上面的工程，进入工程目录
  3. mvn spring-boot:build-image mac环境注意给docker分配的内存要大，建议8G
  4. 启动docker docker run –rm -p 8080:8080 springnative:0.0.1-SNAPSHOT
  5. 镜像已经上传到dockerhub
  • docker login
  • docker tag springnative:0.0.1-SNAPSHOT
  • thurstonzk2008/springnative:0.0.1-SNAPSHOT
  • docker push thurstonzk2008/springnative:0.0.1-SNAPSHOT
