Easypack之Alpine容器系列：Maven

发起源于Jakata Turbine的项目的Maven, 为项目的标准化构建和发布提供了非常重要的解决方案. Easypack项目中不止期待于软件安装的方便, 更是希望在此基础之上大家能够学习的同时进行新的尝试, 比如CAAS, 因此才引入了很多流行的开源软件的官方改制镜像. 比如Maven提供的功能如何以服务的形式对外提供, 在这篇文章中将会简单提及.

使用场景

Maven提供的打包等服务，而我们只有代码，使用Maven所提供的服务进行打包，这是最简单的服务提供方式之一。我们使用在其他文章使用的spring cloud的Eureka提供的服务注册的模块进行编译，当然你也可以自己其他的pom项目。

中间确认

在mvn package的工程中，确认启动的container的结果

[root@liumiaocn discoveryservice]# docker exec -it maven /bin/sh/usr/src/mymaven # ls -ltotal 40-rw-r--r--    1 root     root         16573 Dec 28 12:30 discoveryservice.iml-rw-r--r--    1 root     root          7058 Dec 28 12:27 mvnw-rw-r--r--    1 root     root          5006 Dec 28 12:27 mvnw.cmd-rw-r--r--    1 root     root          2216 Dec 28 12:27 pom.xmldrwxr-xr-x    4 root     root            28 Dec 28 12:27 srcdrwxr-xr-x    3 root     root            20 Mar 10 14:44 target/usr/src/mymaven # pwd/usr/src/mymaven/usr/src/mymaven #

结果确认

可以看到，虽然没有安装Maven，输入了source，输出的是编译打包之后的结果。

总结

使用Maven的容器提供打包服务，但是repository还是与容器进行关联，结合nexus的服务和本地存储管理会有更好的效果。
