Docker 搭建 ARM 下 Maven 环境

admin

前言

若要将一 Spring Boot 项目对不同架构的平台进行适配,是一件相当麻烦的事,需要在不同架构的平台中进行编译测试。近几年,ARM 架构的终端逐渐盛行,特别是华为推出了移动端的麒麟处理器、桌面端的鲲鹏处理器之后,国内从业者对于 ARM 架构下的软件开发正在迅速发展。但是目前终究还是 x86_64 的天下,不少 Spring Boot 项目并未提供对于 ARM 架构平台的支持。

但是在 ARM 平台下进行环境的搭建也比 x86_64 繁琐,可以采用 Docker 容器来进行 ARM 平台下环境的搭建。

拉取 Maven 镜像

在 Docker Hub Official Image 中可以看到类似如下信息。

TAG
3.8.1-openjdk-17 docker pull maven:3.8.1-openjdk-17
Last pushed 8 days ago by doijanky
DIGEST OS/ARCH COMPRESSED SIZE
9c9cadc63144 linux/amd64 399.55 MB
fc8ec2ca29f9 linux/arm64/v8 378.87 MB

可以看到 Maven 的 Docker IMAGE 是支持 ARMv8 架构的,通过这个镜像我们就可以进行 ARMv8 平台下的编译。

docker pull maven:3.8.1-openjdk-17

启动容器

docker run -itd --name maven-armv8 maven:[TAG] /bin/bash

[GOAL PATH] 为主机 Spring Boot 项目路径, [CONTAINER TARGET] 容器中数据卷的映射地址。

示例:

bash-5.0# docker run -itd --name maven-armv8 maven /bin/bash
3e144c67f2690ad33f1134cd17040b415362ad75d921a64b7d1162a9520a6cd9
bash-5.0# docker ps -a

复制项目进容器

docker cp /home/Yogile/docker/Maven/project/nginxWebUI/ maven-armv8:/root/project

编译打包

进入 /root/project/nginxWebUI 目录进行编译打包。

mvn clean package

示例:

bash-4.4# cd /root/project/nginxWebUI
bash-4.4# ls
Dockerfile  LICENSE  README.md  README_EN.md  jre.tar.gz  nginxWebUI.sh  pom.xml  src
bash-4.4# mvn clean package
