Java应用镜像构建

基础镜像构建

Eclipse Temurin 是一个由 Eclipse 基金会支持的开源 Java 运行时环境（JRE）和 Java 开发工具包（JDK）。它提供了一个高性能、可靠的 OpenJDK 构建版本，旨在为开发人员和企业提供一个免费的、符合标准的 Java 发行版。Temurin 的构建遵循 OpenJDK 的规范，并且得到了持续的社区支持和更新。

JDK8

下载JDK

建议在官方的Web界面下载：地址

wget https://github.com/adoptium/temurin8-binaries/releases/download/jdk8u432-b06/OpenJDK8U-jre_x64_linux_hotspot_8u432b06.tar.gz

创建Dockerfile

安装软件包这条命令中，生产环境中建议最小化安装，软件列表：locales curl fontconfig fonts-dejavu-core fonts-liberation

Java应用镜像构建

原生镜像

基于 基础镜像构建 的镜像直接运行SpringBoot应用程序

运行应用

将宿主机的Jar文件映射到容器内部，然后自定义启动参数运行应用

docker run --rm --name springboot-demo \
    -p 18080:8080 \
    -v $(pwd)/springboot3-demo-v1.0.jar:/opt/app/app.jar:ro \
    registry.lingo.local/service/java:debian12_temurin_openjdk-jdk-21-jre \
    -server \
    -Xms128m -Xmx1024m \
    -jar app.jar \
    --server.port=8080 \
    --spring.profiles.active=prod

应用和镜像一体-命令
