以Java Maven项目为例,在Java Maven项目中新建Dockerfile文件,并在Dockerfile文件添加以下内容。 说明 该Dockerfile文件使用了二阶段构建。 第一阶段: 选择Maven基础镜像(Gradle类型也可以选择相应Gradle基础镜像)完成项目编译,拷贝源代码到基础镜像并运行RUN命令,从而构建Jar包。
示例:LABEL version="1.0" description="My Java application"。 EXPOSE:声明容器运行的服务端口,但并不会实际发布端口。要发布端口,需要在 docker run 时使用 -p 或 -P 参数。 示例:EXPOSE 8080。 ENV:设置环境变量 示例:ENV JAVA_HOME=/usr/local/openjdk-17。 ADD:将本地文件、目录或远程 URL 添加到...
